His , often described as brushing the ball with high (RPM), allowed him to construct points through consistent, looping rallies that wore down opponents. Complementing this was a one-handed capable of similar , enabling him to redirect pace effectively and maintain rally length. One of Vilas's primary strengths was his exceptional , which permitted him to engage in prolonged rallies and outlast adversaries in grueling matches. Under the guidance of coach , his training regimen emphasized rigorous fitness, including extended practice sessions that could last up to nine hours, building the stamina needed for his defensive-oriented game. This physical conditioning was pivotal on clay courts, where Vilas excelled through a proficient sliding —placing his foot sideways for control, akin to —and shots that exploited the surface's high bounce to keep the ball deep and unpredictable. However, his style proved less effective on faster surfaces like grass or hard courts, where the lower bounce and quicker pace disrupted his topspin-heavy approach, leading to vulnerabilities against aggressive net players. Vilas played with wooden rackets throughout his career, including models from brands like , which suited his spin-oriented technique during the pre-graphite era. His evolved notably under Țiriac's influence, shifting from an early-career reliance on aggressive serving and to a more consistent, defensive baseline strategy that prioritized rally construction and error minimization in his peak years. This adaptation enhanced his clay-court mastery, where he could dictate tempo through endurance and rather than outright aggression.

Key opponents and head-to-heads

One of the defining rivalries in Guillermo Vilas's career was against , with Borg holding a dominant 17-5 head-to-head advantage across 22 matches. Their encounters often highlighted contrasting styles, with Borg's baseline precision overpowering Vilas's endurance on various surfaces, particularly clay.

Năstase's unorthodox shot-making tested Vilas's consistency on European red clay, but Vilas's superior stamina prevailed in most decisive meetings, aiding his rise in clay rankings and accumulating vital points toward his 1977 peak. Among other notable opponents, Vilas held a 6-8 record against , with McEnroe leading overall, though early encounters favored the Argentine, including a 1978 Basel final win that tested his adaptability before McEnroe's grass-court mastery shifted later dynamics.

In parallel to the ATP computer rankings, Vilas topped the Grand Prix points system in 1974, 1975, and 1977, earning recognition as the season's leading player those years based on tournament results and overall points accumulated. Vilas maintained a presence in the ATP top 10 for eleven consecutive years from 1974 to 1984, showcasing remarkable consistency in an era dominated by and Bjorn Borg, against whom he often ranked just behind in the official computer standings. Post-1980, his rankings began to fluctuate and decline due to recurring injuries and a nine-month suspension in 1983 for participating in too many non-ATP events, which limited his tournament participation and points accumulation. By the mid-1980s, he had fallen outside the top 20, though he continued competing until 1992.

No. 1 ranking dispute

The No. 1 ranking dispute for Guillermo Vilas primarily revolves around his dominant 1977 season, during which he won 17 tournaments—including the and US Open—and compiled a 145-14 win-loss record, yet finished the year ranked No. 2 behind , who won eight titles but no majors. Critics argue that the ATP's early computerized ranking system, introduced in , failed to fully account for Vilas's results, particularly from South American clay-court events and non-Grand Prix tournaments, leading to an erroneous exclusion from the top spot. Recalculations based on comprehensive match data indicate that Vilas accumulated the highest points total for much of 1977, underscoring his status as the world's leading player that year. Argentine journalist Eduardo Puppo spearheaded a 13-year starting in 2007, collaborating with Romanian mathematician Marian Ciulpan to review over 23,000 matches and reconstruct from August 1973 to December 1978—a period spanning 280 weeks. Their findings, compiled in a 1,200-page submitted to the ATP in 2014, revealed that Vilas should have held the No. 1 ranking for at least seven weeks: five weeks beginning September 22, 1975, and two weeks in early January 1976, based on corrected points calculations that included previously omitted results. Extending the analysis to 1974-, the research demonstrated Vilas consistently topped the overall points standings during key periods, including his 1977 peak, despite the original formula's irregular updates every four to six weeks and exclusions of certain events. The ATP investigated Puppo's evidence in but declined to retroactively award Vilas the No. 1 ranking, with then-CEO Chris Kermode citing concerns over opening the door to similar historical revisions and technical discrepancies in the pre-weekly ranking era. In 2019, the ATP Board closed the case without changes, prompting ongoing campaigns in during the , including legal efforts by Puppo with sports lawyers and a 2020 Netflix documentary, Vilas: Settling the Score, which amplified public and cultural support from figures like . In May 2024, an ATP vice-president confirmed that Vilas would never be retroactively awarded the No. 1 ranking.
