Peter Doohan
Peter Doohan (2 May 1961 – 21 July 2017) was an Australian professional tennis player renowned for his stunning second-round upset victory over world No. 2 Boris Becker at the 1987 Wimbledon Championships, defeating the defending champion 7–6, 4–6, 6–2, 6–4 while ranked No. 70.[1][2] A right-handed player, Doohan turned professional after a standout college career at the University of Arkansas, where he was an All-American in doubles in 1981 and 1982 and won the NCAA doubles title in 1982 with partner Pat Serret.[3][2] Doohan's professional highlights included one ATP singles title at the 1984 Adelaide International and five doubles titles, notably the 1987 Australian Open doubles runner-up finish with Laurie Warder.[4][3] His career-high singles ranking was No. 43 in August 1987, following his Wimbledon run to the fourth round, and his doubles peak was No. 15 in February 1987.[4] Over his career, he competed in 19 Grand Slam tournaments and represented Australia in the Davis Cup, securing three doubles wins in 1987.[1] Born in Newcastle, New South Wales, Doohan amassed $445,192 in prize money before retiring from the ATP Tour in 1996.[5] Post-retirement, he coached tennis in the United States and Australia, serving as head professional at the Grand Racquet Club in Tulsa, Oklahoma, and was inducted into the University of Arkansas Sports Hall of Fame in 2003 and posthumously into the ITA Men's Collegiate Tennis Hall of Fame in 2025.[3][4][6] He died at age 56 from amyotrophic lateral sclerosis (ALS), diagnosed just nine weeks earlier, survived by his two sons, John and Hunter.[2]Early life and education
Family background and childhood
Peter Doohan was born on 2 May 1961 in Newcastle, New South Wales, Australia, a regional industrial city known for its working-class heritage rooted in coal mining and steel production.[7][8] He grew up in this coastal community, where his family embodied the area's modest, resilient ethos; his father Paul and mother, Thelma Doohan, raised the family, and he had two sisters, Cathie and Margaret, with whom he shared close ties throughout his life.[7][8][9] The family's Newcastle origins underscored a grounded, community-oriented upbringing typical of the region's blue-collar families.[8] Doohan's formative years were spent in Newcastle, where he attended Merewether High School and first developed an interest in sports amid the local culture of outdoor recreation.[10] The city's parks and beaches provided ample opportunities for physical activity, shaping his early athletic pursuits in a environment that valued teamwork and perseverance over early specialization.[8] No major relocations marked his childhood, allowing deep roots in the Hunter Region's social fabric, though key events like community sports days likely reinforced his competitive drive. His introduction to tennis came during these school years, sparked by weekend sessions at District Park in Broadmeadow, a public facility central to Newcastle's grassroots sports scene.[10] Under the guidance of local coach Frank Brent, Doohan honed his skills in informal junior settings, progressing from casual play to structured development that highlighted his potential as a determined baseline player.[10] This early exposure in Australia's regional tennis ecosystem laid the groundwork for more formal training opportunities that would later attract international attention.University of Arkansas tenure
Peter Doohan enrolled at the University of Arkansas in 1980, where he pursued a business degree while competing for the Razorbacks men's tennis team through 1983.[11] As an Australian recruit drawn to U.S. college tennis for its competitive opportunities, Doohan quickly emerged as a standout player under coach Tom Pucci.[6] During his tenure, Doohan earned six ITA All-American honors, including selections in both singles and doubles from 1980 to 1983, highlighting his versatility and dominance on the court.[12] In doubles, he partnered with fellow Australian Pat Serret to reach the NCAA final in 1981, advancing through the bracket to face Texas Christian University's David Pate and Karl Richter in the championship match, where they finished as runners-up.[3] The duo redeemed that performance the following year, capturing the 1982 NCAA doubles title after defeating Miller and Malmqvist in a three-set final, 7–6(7–5), 5–7, 6–2, marking Arkansas's first and only NCAA doubles championship to date.[13] Doohan's contributions extended to team success, helping the Razorbacks secure Southwest Conference championships in 1980 and 1981 while qualifying for the NCAA Championships each year from 1980 to 1983.[12] He amassed impressive personal records, including 96 career singles victories and 96 career doubles wins, still among the program's all-time leaders, with a standout 30–5 singles mark in 1980.[12] These achievements elevated the Razorbacks' profile nationally, establishing Doohan as arguably the greatest player in program history and earning him posthumous induction into the ITA Men's Collegiate Tennis Hall of Fame in 2025.[6]Personal life
Marriage and family
Doohan was married to Angie Doohan (née Harper), a university graduate from Arkansas, with whom he had two sons, John and Hunter, during their marriage in the 1980s and 1990s.[14][15] The couple divorced prior to his death but maintained a close relationship with their children, who were raised primarily in the American South, including Arkansas, where Doohan coached tennis after his playing career.[7] John Doohan followed his father's footsteps into tennis, becoming a coach and winning titles such as the 2011 Arkansas Men's Open Doubles championship, while Hunter pursued acting, gaining recognition for his role as Tyler Galpin in the Netflix series Wednesday.[15][7] The family offered vital emotional support during Doohan's extensive travels on the ATP Tour and Davis Cup commitments, often managing home life across Australia and the United States to accommodate his professional demands.[14] In tributes following his passing, Doohan's sons publicly reflected on his profound influence, praising his quick wit, unwavering family loyalty, and love for the Newcastle Knights rugby league team during emotional speeches at his August 2017 funeral in Newcastle, Australia.[16] This sense of familial bond extended into his later years, as the family briefly reunited in Australia before his health declined, tying into his return to Nelson Bay for stability.[7]Residence and later years
Following his collegiate years at the University of Arkansas in Fayetteville, where he resided during his studies from 1980 to 1984, and subsequent early professional tennis career spent primarily in Arkansas, including time in Fort Smith, Peter Doohan returned to Australia in 2009 after two decades abroad.[17][7][16] Doohan established his primary residence in Nelson Bay, New South Wales, a coastal town in the Port Stephens region, where he lived overlooking local beaches and enjoyed the tranquility of regional Australia.[18][7] In his post-retirement years, Doohan adopted a low-key lifestyle as a private citizen, focusing on community involvement through the promotion of local tennis via club-based competitions and partnerships with nearby resorts to enhance accessibility for residents and visitors.[19][20] His personal interests included staying connected to the sport by following major tournaments and revisiting career highlights through video footage.[18] Family provided support in sustaining his home in Nelson Bay during this period.[7]Professional tennis career
Transition to professional circuit
Following his successful college tenure at the University of Arkansas, where he graduated in 1983, Peter Doohan turned professional that year, marking his entry into the ATP Tour circuit. Starting unranked, Doohan focused on building experience through challenger-level events and lower-tier tournaments, gradually accumulating points to climb the rankings. By the end of 1984, his efforts paid off as he broke into the top 100 for the first time, laying the groundwork for further progression despite remaining outside the elite levels through 1986, when he ended the year ranked No. 301.[3][21] Doohan's breakthrough came in 1984 at the Australian Hard Court Championships in Adelaide, where he captured his only ATP singles title by defeating Huub van Boeckel in the final 1–6, 6–1, 6–4. This victory, held on grass courts, highlighted his adaptation to professional competition and boosted his confidence on home soil. These successes demonstrated Doohan's growing prowess in singles, though the event's status varied in prestige across years.[4][3] In doubles, Doohan leveraged his collegiate achievements—where he secured an NCAA title in 1982—as a springboard to professional partnerships, winning his first two ATP doubles titles in 1985 at Newport with Sammy Giammalva Jr. and at the Tokyo Outdoor Championships with David Macpherson, establishing early momentum in the discipline amid the demands of adapting to the international schedule's rigors, including extensive travel from Australia. These initial accomplishments reflected his versatility while navigating the financial and logistical hurdles typical for non-European players on the global circuit during the era.[3]Key achievements and 1987 breakthrough
Peter Doohan's professional tennis career reached its zenith in 1987, marked by a significant surge in performance and visibility following his breakthrough victory at Wimbledon. Earlier, his 1984 triumph at the Adelaide International, where he defeated Huub van Boeckel in the final to claim his first ATP singles title, provided crucial momentum by establishing him on the tour after transitioning from college tennis. This grass-court success foreshadowed his later prowess on the surface, building confidence for higher-level competitions.[22][23] The pinnacle of Doohan's achievements came at the 1987 Wimbledon Championships, where he orchestrated one of the tournament's most shocking upsets by defeating defending champion and world No. 2 Boris Becker in the second round. Ranked No. 70 at the time, Doohan won 7-6(4), 4-6, 6-2, 6-4 on Court No. 1, exploiting soggy court conditions from prior rain that dulled Becker's powerful serve and allowed Doohan to return aggressively.[24][25][26] In the match, Doohan, coached by countryman and former player Michael Fancutt, targeted Becker's backhand with deep returns, forcing errors in prolonged rallies and breaking serve decisively in the third and fourth sets after a competitive tiebreak opener. The upset earned Doohan the enduring media nickname "Becker Wrecker," highlighting his tactical acumen against a player who had dominated Wimbledon in 1985 and 1986. Just two weeks prior, Becker had beaten Doohan 6-2, 6-4 at Queen's Club, but improved footing on the drier Wimbledon grass enabled Doohan's low, skidding returns to disrupt Becker's rhythm.[27][1][28] Doohan's 1987 season featured additional highlights, including a runner-up finish at the New South Wales Open in Sydney, where he fell to Miloslav Mečíř in the final, and a fourth-round appearance at the Australian Open. He also captured the singles title at the Martinique Challenger in April, contributing to an overall singles record that propelled him from No. 301 at year-end 1986 to No. 72 by December 1987, with career-high earnings of $101,020. In doubles, he reached the final at the Australian Open alongside Laurie Warder and achieved a career-best ranking of No. 15.[3][29][30][31] The Wimbledon victory dramatically elevated Doohan's profile, propelling him into the ATP top 50 for the first time and opening doors to seeded entries and higher-profile events, though he ultimately lost in the fourth round to Pat Cash. This breakthrough not only cemented his reputation as a grass-court specialist but also amplified Australian tennis interest ahead of Cash's eventual title win that year.[32][33][1]Later professional years and retirement
Following his peak in 1987, Doohan's singles ranking declined sharply in the late 1980s and into the 1990s, reflecting the challenges of sustaining momentum as a journeyman player on the ATP Tour. In 1988, he recorded a 4-13 win-loss mark in singles, a stark contrast to his breakthrough year, while his year-end ranking plummeted to No. 187.[3][30] His overall career singles record stood at 49-81 upon retirement, underscoring a trajectory of consistent but limited success against top competition.[5] Doohan found greater stability in doubles during this period, securing his final two ATP titles in 1988 at Bristol and 1989 at Wellington, both with partner Laurie Warder; this capped his five career doubles victories.[3] These achievements highlighted his reliability as a doubles specialist, reaching a career-high doubles ranking of No. 15 earlier in his career.[4] As his playing career wound down amid the physical demands of the tour, Doohan competed in fewer events through the early 1990s, with his last professional matches occurring in 1996 before officially retiring from the ATP Tour that year.[3] Known for his tenacity as an underdog who often exceeded expectations despite modest rankings, Doohan's longevity exemplified the grit required to navigate over a decade on the professional circuit. During these waning years, he began planning a shift toward coaching and club instruction, laying the groundwork for his post-playing roles at U.S. country clubs.[3]Davis Cup and team events
1987 Davis Cup contributions
Peter Doohan was selected for Australia's 1987 Davis Cup team, where he played a pivotal role in the doubles rubber across all three World Group ties, remaining unbeaten in his matches.[34] His inclusion followed a strong start to the year and was further highlighted by his upset victory over defending champion Boris Becker at Wimbledon in July, which elevated his profile ahead of the later rounds.[1] In the first-round tie against Yugoslavia in Adelaide from 13–15 March, Doohan partnered with Pat Cash in the doubles match, defeating Slobodan Živojinović and Igor Flego 9–11, 7–5, 6–3, 6–4 on grass. This victory contributed to Australia's 4–1 overall win, advancing them to the quarterfinals. Doohan's net play and steady serving proved effective in the comeback after dropping the opening set, showcasing his tactical awareness in team competition. The quarterfinal against Mexico in Mexico City from 24–26 July saw Doohan team with Wally Masur in doubles, rallying to beat Leonardo Lavalle and Jorge Lozano 3–6, 6–4, 4–6, 8–6, 13–11 on hard courts in a grueling five-setter that lasted over four hours. This result helped secure another 4–1 triumph for Australia, with Doohan's resilience in tiebreaks and ability to adapt to the altitude and surface drawing praise for stabilizing the partnership during momentum shifts. Media outlets highlighted his doubles expertise as a key factor in overcoming the hosts' challenge, distinct from his individual ATP performances due to the pressure of national representation. In the semifinals versus India in Sydney from 2–4 October, Doohan reunited with Cash for the doubles, dominating Anand Amritraj and Vasudevan Srinivasan 6–3, 6–4, 6–4 on grass to level the tie at 2–1 after India had taken an early lead. Despite this strong performance, Australia fell 2–3 overall when Ramesh Krishnan won the decisive fifth rubber. Contemporary reports noted Doohan's aggressive volleying and synergy with Cash as instrumental in the straight-sets win, underscoring his preparation focused on high-stakes team dynamics rather than routine tour events.[35] His three doubles victories were central to Australia's semifinal progression, marking a standout contribution to the defending champions' campaign.[36]Overall team representation
Peter Doohan's involvement in Australian national team tennis was confined to the Davis Cup, where he represented his country exclusively in 1987 across three ties in the World Group.[34] Selected as a doubles specialist, Doohan was chosen for his strong partnership play and high-level doubles ranking, which peaked at No. 15 that year, complementing the team's singles strengths led by players like Pat Cash and John Fitzgerald.[5] His role emphasized reliable doubles contributions to maintain momentum in ties, particularly on grass courts where Australia's home advantage was pronounced.[37] Doohan competed in all three doubles rubbers that year, partnering with Pat Cash against Yugoslavia and India, and with Wally Masur against Mexico: a victory over Yugoslavia's Slobodan Živojinović and Igor Flego in the first round (9–11, 7–5, 6–3, 6–4), Mexico's Leonardo Lavalle and Jorge Lozano in the quarterfinals (3–6, 6–4, 4–6, 8–6, 13–11), and India's Anand Amritraj and Vasudevan Srinivasan in the semifinals (6–3, 6–4, 6–4).[38][39][36] These wins helped propel Australia to the semifinals as defending champions, though the team ultimately fell to India 3–2.[40] His perfect 3–0 Davis Cup record underscores his effectiveness in team settings, marking him as an unbeaten contributor during a transitional era for Australian tennis following the dominance of earlier legends like Rod Laver.[41] Doohan's doubles expertise, honed through ATP successes including a Grand Slam doubles final, solidified his value to the squad amid a competitive international landscape.[5] No records indicate participation in other international team events like the Hopman Cup or regional competitions during his professional career.[42]Grand Slam performances
Singles highlights
Peter Doohan competed in 19 Grand Slam singles main draws between 1979 and 1991, primarily during his professional career from 1984 to 1990, achieving an overall win-loss record of 10-19 in these events.[43] His appearances were concentrated on hard courts at the Australian Open and grass at Wimbledon, reflecting his strengths as a serve-and-volley player suited to faster surfaces, though he ventured sparingly to clay at the French Open.[3] Doohan's best Grand Slam result came in 1987, when he reached the fourth round at both the Australian Open and Wimbledon, marking a breakthrough year that elevated his ranking to a career-high No. 43. At the Australian Open, benefiting from home advantage in Melbourne, he advanced past Desmond Tyson, Bill Scanlon, and Kevin Curren before falling to Anders Järryd in a tight four-set match, 6-1, 6-7(5), 6-4, 7-6(5).[44] This performance highlighted his competitive edge on familiar hard courts, where he secured six of his ten Grand Slam victories. Earlier, in 1985, he progressed to the third round at the Australian Open by defeating Andrei Chesnokov and Todd Nelson, only to lose to Johan Kriek, 7-5, 6-4, 6-0.[44] He reached the second round there in 1988, defeating Steve Guy before exiting to Henri Leconte.[44] At Wimbledon, Doohan's 1987 run to the fourth round remains his most notable, capped by a stunning second-round upset over defending champion and world No. 2 Boris Becker, 7–6(2), 4–6, 6–2, 6–4, before defeating Leif Shiras in five sets and losing to Slobodan Živojinović.[1] This grass-court success underscored his preference for the surface, where his powerful serve thrived, though prior (1980, 1982, 1985, 1986) and subsequent (1988) appearances ended in first-round defeats.[45] Doohan's U.S. Open results were modest, with a career-high second round in 1984, where he beat Lloyd Bourne but lost to Henri Leconte, 7-5, 6-4, 7-5; he exited in the first round in 1985 (to Becker) and 1987 (to Brad Gilbert).[46] His sole French Open entry in 1986 ended in a first-round loss to John Fitzgerald, 3-6, 6-2, 6-0, 4-3 ret., limiting his exposure on clay.[47] Despite never reaching a Grand Slam quarterfinal, these highlights demonstrated Doohan's potential against top competition on his favored surfaces.[43]| Tournament | Appearances | Best Result | Win-Loss |

Doubles and mixed doubles results
Peter Doohan's Grand Slam doubles career featured notable success on hard courts and grass, with his best result coming as runner-up at the 1987 Australian Open alongside Laurie Warder, where they fell to Stefan Edberg and Anders Järryd 6–4, 6–4, 7–6(7–5) in the final.[31][3] This marked his only Grand Slam doubles final appearance and highlighted his effectiveness on the fast indoor hard courts of the time, contributing to his career-high doubles ranking of world No. 15 achieved in February 1987.[4][3] Earlier in his career, Doohan reached the semifinals at the 1984 Australian Open with partner Michael Fancutt, demonstrating early promise in doubles on home soil before the tournament moved to its outdoor hard courts.[3] Transitioning to grass, he advanced to the semifinals at the 1984 Wimbledon Championships with Fancutt, upsetting seeded pairs en route but ultimately losing in straight sets to the Gullikson brothers, Tim and Tom, 6–1, 6–3, 6–4.[3] Doohan repeated his Wimbledon semifinal success in 1988, this time partnering American Jim Grabb; they defeated strong competition, including a quarterfinal win over Darren Cahill and Mark Kratzmann, before falling to Guy Forget and Tomáš Šmíd 6–4, 7–6(7–2), 4–6, 6–7(5–7), 6–4.[3] In 1989, Doohan and Warder progressed to the Wimbledon quarterfinals, showcasing consistent grass-court prowess with Warder as a frequent and successful partner across surfaces.[3] Doohan's Grand Slam doubles appearances totaled approximately 10 across his professional tenure from 1984 to 1990, often reaching at least the third round in events like the US Open in 1988 and 1990, though he did not advance beyond that stage there. Key partnerships, including with Fancutt on grass and hard courts and Grabb on grass, underscored his versatility, while his limited French Open participation—such as a second-round exit in 1989—reflected fewer opportunities on clay.[3] In mixed doubles, Doohan's involvement was minimal, with a third-round appearance at the 1984 Wimbledon Championships partnering Anne Lepidus, including a first-round victory over Todd Nelson and Caryn Copeland 7–5, 6–7(6–8), 6–3. His best result in the discipline was a semifinal at the 1989 Australian Open with Elise Burgin, where they lost to the eventual champions Jana Novotná and Jim Pugh 6–3, 6–4; he recorded no titles at the majors.[48]| Tournament | Year | Partner | Best Result | Opponents in Key Match |

ATP Tour finals
Peter Doohan competed in four ATP Tour singles finals, achieving one title and three runner-up finishes. His breakthrough singles victory occurred at the 1984 South Australian Open in Adelaide, a Grand Prix event on grass courts, where he came back to defeat qualifier Huub van Boeckel 1–6, 6–1, 6–4 in the final on December 17. This win, shortly after turning professional, provided an early boost to his career and prize money earnings, helping establish him on the circuit. Doohan reached the final again at the 1985 South Australian Open in Adelaide, losing to Eddie Edwards 6–2, 6–4 on grass; at the 1985 Australian Open Hardcourts in Melbourne, falling to Jonathan Canter 6–4, 3–6, 6–3 on hard courts; and at the 1987 Sydney Outdoor, where he was defeated by Miloslav Mečíř 6–2, 6–4 on grass. These finals, primarily on familiar Australian surfaces, demonstrated his potential but highlighted challenges against top-ranked opponents in decisive matches.[49]| Year | Tournament | Surface | Opponent | Result |

Challenger and Futures finals
Doohan competed in several ATP Challenger events throughout his career, particularly in 1988, when these tournaments served as key opportunities to accumulate ranking points and regain momentum during a challenging season on the main tour. These lower-tier professional events allowed him to compete on clay and hard courts in international locations, honing his game against emerging talents and established players while preparing for higher-level competitions. Although his involvement in ITF Futures circuits was minimal, reflecting his transition from collegiate tennis directly into more prominent professional pathways, his Challenger results demonstrated depth and occasional success in developmental play. In singles, Doohan reached three Challenger finals in 1988, achieving a 1–2 record. He secured his sole Challenger singles title at the San Luis Potosí Challenger in Mexico on clay, defeating Agustín Moreno 6–4, 6–4 in the final. Later that year, he was runner-up at the Lisbon Challenger in Portugal on clay, where Alberto Mancini defeated him 6–3, 6–2. His third final came at the Mexico City Challenger on hard courts, falling to Tom Mercer 6–3, 6–4. These appearances contributed valuable ATP ranking points, helping stabilize his position in the 100s during a year marked by inconsistent main-tour results. Doohan's doubles success in Challengers was more pronounced that same year, with two titles alongside partner Michael Fancutt. They won the Vilamoura Challenger in Portugal on hard courts, beating Stéphane Bonneau and Fabio Silberberg 6–4, 6–3 in the final. Shortly after, at the Mexico City Challenger, the pair claimed another victory, though specific final details underscore their effective teamwork in building confidence for doubles events. These wins highlighted Doohan's versatility in team formats and provided essential points toward his career-high doubles ranking of No. 15.| Year | Tournament | Surface | Category | Result | Opponent(s) | Score |
