PitchCom

PitchCom is a communication system designed for that enables catchers to transmit pitch calls directly to pitchers and select fielders via audio signals, eliminating the need for visible and thereby preventing sign-stealing while accelerating the pace of play. Developed in response to high-profile sign-stealing scandals, such as the 2017 Houston Astros controversy, PitchCom was introduced to (MLB) during 2022 as an electronic alternative to traditional signaling methods. The system utilizes a transmitter worn on the catcher's , which allows selection from up to 18 pre-programmed pitch options (including location and type), vocalized audibly through a in the pitcher's cap or earpiece. Up to three additional receivers can be assigned to infielders for strategic communication. Following its debut, PitchCom was made available to all 30 teams for the 2022 regular season, leading to rapid adoption across MLB, though individual players could opt out. By 2023, rules expanded to allow pitchers to wear transmitters for relaying information back to catchers, increasing each team's allocation to three transmitters and 12 receivers. The device's implementation has contributed significantly to shorter game times, with the average nine-inning MLB game in 2023 lasting 2 hours and 39 minutes—the shortest since 1985—and a 24-minute reduction from 2022 alone, complementing the pitch clock rules. MLB extended its exclusive vendor agreement with PitchCom through at least the 2026 season in February 2024, providing the system to all major league clubs and Triple-A affiliates to further enhance game efficiency and security. Beyond professional baseball, PitchCom has been integrated into collegiate programs, such as the University of Texas Rio Grande Valley in 2025, and youth tournaments through partnerships like . In 2025, the NCAA approved on-field use of transmitters, and partnered with PitchCom for events throughout the season, broadening its application while maintaining a focus on secure, real-time on-field communication without reliance on cellular or Wi-Fi networks. Early challenges, including connectivity glitches and audio interference from crowd noise, have been largely addressed through updates, leading to widespread player approval for its role in reducing mound visits and strategic vulnerabilities.

History and Development

Invention

PitchCom was invented by John Hankins, a retired and performer, and Craig Filicetti, an electrical engineer and founder of ProMystic, a company specializing in magic apparatus. The device originated from their expertise in creating covert communication tools for magic shows and acts, where discreet signaling is essential to preserve illusions and enable seamless coordination between performers. Filicetti had previously developed "Live Show Control," a compact player-like device that allowed magicians to trigger audio cues secretly during live performances, often worn inconspicuously on the body. Early prototypes built on these concepts, featuring basic wireless audio systems tested in non-sports environments to ensure reliable, low-profile transmission of instructions without visual cues. These iterations, adapted from needs, initially used technology for private audio delivery and simple button interfaces for selecting pre-recorded messages, though was later abandoned in favor of in-ear receivers due to volume issues in settings. The adaptation for baseball stemmed from growing concerns over sign-stealing in , particularly following the 2017 Houston Astros scandal that highlighted vulnerabilities in traditional . Hankins, a lifelong enthusiast, envisioned repurposing the magicians' methods to protect pitch calls from interception.

Testing and Introduction

PitchCom underwent its initial testing in the Low-A West during the 2021 season, beginning on August 3 with eight teams equipped with the device to evaluate its effectiveness in relaying signs electronically. The trials focused on practical in game settings, revealing successes in communication speed while identifying minor issues like user error, which informed subsequent refinements. Following positive results from the tests and additional evaluations during 2022 , officially approved PitchCom for use in the 2022 regular season to combat and accelerate the pace of play by eliminating traditional finger signals. This approval marked a significant step in integrating the technology league-wide, with initial adoption optional for teams to ensure smooth rollout. Key milestones in PitchCom's development included the introduction of wristband transmitters for pitchers during , allowing them to call pitches directly to catchers and further streamlining conferences. By , the system achieved full integration with MLB's rules, enhancing overall game tempo by reducing delays in sign relay. In early partnerships, MLB designated PitchCom as its exclusive vendor for signal-calling systems, with the agreement extended through the 2026 season, announced on , 2024, to support ongoing and league-wide consistency.

Technology

Components

The PitchCom system comprises two primary hardware components: a transmitter worn by the (or, since 2023, also by for ) and receivers utilized by the , , and select fielders. The transmitter, known as the PitchRemote, is a compact, wristband-like device featuring a nine-button designed for inputting pitch types and locations, along with additional controls including a cancel button, volume adjustment buttons, a micro USB charging port, an integrated , and status indicator LEDs. It is secured on the 's (or 's) inner or via an adjustable for unobtrusive wear during play. The receivers, referred to as PitchCaps, are small, lightweight earpieces that employ bone-conduction technology to deliver audio signals directly to the user's without blocking ambient sound. These devices, which include volume control buttons, a micro USB port, a opening, and a charging indicator LED, can be embedded into the brim of the pitcher's , catcher's , or attached to the uniforms of up to three infielders for discreet reception. Each receiver unit measures approximately the size of a small curved insert, ensuring minimal with player movement. Since 2023, MLB teams are allocated up to 12 receivers per game. Power for both components is provided by rechargeable lithium-ion batteries, with the transmitter offering over 24 hours of operational life per charge and each providing at least 5 to 6 hours of continuous use, sufficient for a full game with recharging recommended afterward. The system's design emphasizes durability for outdoor sports environments, incorporating weather-resistant materials and low-maintenance construction to withstand field conditions such as moisture and impacts. Security is achieved through encrypted radio frequency signals transmitted directly between the transmitter and receivers, eliminating reliance on cellular networks or to minimize interception risks. The audio content, including customizable elements such as multiple languages and user-defined code words stored as tracks, is pre-loaded via USB for team-specific configurations.

Operation

During a baseball game, the (or , since 2023) initiates the PitchCom signal process by pressing buttons on the wristband transmitter while the is in the set position. The device features a , typically with nine buttons arranged in a grid, allowing the user to select from various pitch types (such as , , or ) and locations (e.g., high-inside, low-outside) by combining presses—up to 81 possible combinations in standard configurations. Upon selection, the transmitter sends an encrypted radio signal via a 915 MHz directly to receivers embedded in the 's , the 's , and optionally up to three fielders' caps or belts, converting the input into a pre-recorded audio message that plays instantly in the recipients' earpieces, such as " low-inside." The audio relay is fully customizable, supporting English, Spanish, and additional languages, with teams able to program unique code words or phrases instead of standard terminology to enhance security and familiarity—changes can be loaded in minutes via a connected . Volume levels are adjustable across 20 settings to suit ambient noise or player preference. The (or transmitting player), wearing a , confirms the message by hearing the audio in their own device before the pitch is delivered. Fielder involvement extends the system's utility for defensive shifts, as the catcher can direct the same signal to up to three additional players, such as the middle infielders and , who wear receivers in their caps or belts to adjust positioning in real time. Coaches program these restrictions in advance, specifying which fielders receive signals and limiting access to prevent overload. The entire transmission occurs in under one second, maintaining game pace. Since 2023, the system supports bidirectional communication when pitchers wear transmitters. Integration with baseball rules ensures seamless use: signals are prohibited during mound visits or timeouts to avoid disruptions, and the system deactivates automatically when the pitcher steps off the rubber, reactivating only from the set position to comply with timing regulations. This communication from transmitter wearer to recipients eliminates visible signs, reducing the risk of interception while streamlining calls.

Adoption

Major League Baseball

Major League Baseball approved the use of PitchCom for the 2022 regular season as an optional tool for catchers to transmit pitch calls electronically to pitchers and up to three fielders, aiming to deter sign-stealing and accelerate the pace of play in alignment with the league's rules. The device was not required, allowing teams and players to continue traditional finger signals if preferred, but its integration supported the 15-second pitch clock between innings by eliminating time spent on visible signaling. The introduction of PitchCom, along with the , contributed to an average nine-inning game time reduction of about six minutes in 2022 compared to 2021, partly attributed to faster signaling. By the end of the 2022 season, all 30 MLB teams had incorporated PitchCom into their games to varying degrees, with many using it consistently to streamline communication. In 2023, MLB expanded access by permitting pitchers to optionally wear PitchCom transmitters on their wrists, enabling them to call their own pitches directly to s and fielders, further reducing between-pitch consultations. Under the updated rules, each team could possess up to three transmitters and 12 receivers, with a maximum of two transmitters active on the field at once—one for the and one for the pitcher—while receivers could be distributed to defensive players as needed. Early adoption faced technical hurdles, notably with the New York Yankees in April 2022, where pitchers and reported audio interference from crowd noise overwhelming the device's volume during games. These issues were promptly addressed through volume adjustments and device tweaks, allowing seamless continued use. MLB secured an exclusive vendor agreement with PitchCom through the 2026 season to standardize equipment across . Ongoing rule refinements have allowed PitchCom receivers for all defensive positions in limited scenarios, such as relaying pickoff or defensive alignments, beyond primary pitch-calling to enhance overall field coordination without disrupting game flow.

Other Leagues and Levels

PitchCom has seen adoption in several international leagues, enhancing pitcher-catcher communication and reducing sign-stealing risks. In , the (KBO) approved and distributed PitchCom devices to its teams for immediate optional use starting in July 2024, following suggestions from general managers to incorporate the technology during the season. Similarly, Taiwan's (CPBL) introduced PitchCom as part of its 2024 rule changes, allowing its use throughout the season, including the championship series won by the . At the college level, PitchCom's integration has expanded significantly in the United States. The (NCAA) approved the broader use of one-way communication devices, including on-field transmitters, for the 2025 baseball season, enabling catchers and coaches to relay pitch calls and offensive signals directly to players. In July 2024, the (SEC) announced an exclusive agreement with PitchCom to serve as the official on-field communication system for all its baseball programs, providing standardized technology across its member institutions. This adoption has been widespread, with the majority of top Division I (D1) programs utilizing PitchCom for the 2025 season, including nearly all participants in the Men's —such as seven of the eight teams in the 2025 event—and the past three national champions. In and , PitchCom has formed key partnerships to bring professional-grade tools to younger players. In May 2025, , a leading youth baseball organization, entered an exclusive partnership naming PitchCom as its official on-field communications provider, deploying the systems at major events to eliminate and improve game flow for travel teams and tournaments. This initiative supports amateur development by mirroring technologies used in higher levels, fostering secure and efficient communication from an early age. Globally, PitchCom has expanded to professional leagues beyond , including those in the , , and , where it supports secure signal transmission without reported thefts across millions of calls.

Reception and Impact

Benefits

One of the primary benefits of PitchCom is its efficacy in preventing , addressing vulnerabilities exposed by scandals such as the 2017 Houston Astros incident, where opponents exploited visible signals through electronic means. By replacing traditional finger signals with encrypted wireless audio transmissions, PitchCom ensures that pitch calls are not visible or interceptable, and since its MLB debut in 2022, no sign-stealing incidents have been reported league-wide. PitchCom also accelerates the pace of play by enabling near-instantaneous communication, with each pitch call transmitted in less than one second via pre-recorded audio. This efficiency has contributed to shorter game durations; for instance, the Yankees completed 25 of their first 54 games in in under three hours—nearly half—compared to just 25% the previous season. Overall, the average nine-inning MLB game lasted 2 hours and 39 minutes in 2023, 2 hours and 36 minutes in 2024, and 2 hours and 38 minutes in 2025, the shortest durations since 1985, 1981, and 1981, respectively, complementing the rules. The system's seamless integration with MLB's further promotes quicker readiness between pitches, reducing downtime without compromising strategic depth. For players, PitchCom empowers pitchers to take greater control over their sequences, allowing them to call pitches directly through the device and dictate the game's tempo, which helps maintain focus and rhythm during innings. Managers have highlighted this as a key advantage for efficiency; for example, manager praised the technology for streamlining pitcher-catcher interactions and enhancing overall performance. Additionally, PitchCom's support for multiple languages via customizable encrypted channels benefits non-native English speakers, who comprise a significant portion of MLB rosters, by facilitating clear communication without language barriers. This accessibility ensures equitable participation and readiness, aligning with the to foster a more inclusive and fluid on-field experience.

Criticisms

PitchCom has faced several technical challenges since its introduction, particularly related to noise interference and signal audibility in loud environments. During the 2022 season, New York Yankees pitchers, including , reported difficulties hearing the device's audio signals amid crowd noise at , exacerbated by the stadium's two-strike alert system that competed with the PitchCom speaker in their hats. Similar issues arose in other games, where excessive stadium volume drowned out the signals, prompting teams like the Yankees to prepare fallback analog methods during high-noise playoff scenarios. Additionally, in spring training 2023, a Minnesota Twins game against the highlighted vulnerabilities when the catcher's PitchCom device was set too loud, allowing opposing hitters to overhear pitch calls clearly; Twins manager confirmed the volume issue enabled the Rays to anticipate every pitch. Strategically, PitchCom has drawn criticism for eliminating traditional sign-stealing elements that some view as integral to baseball's competitive dynamic. pitcher , after using the device for the first time in July 2022, argued it should be "illegal," stating that stealing signs is "part of the game" and fosters a cat-and-mouse interplay between teams that the technology removes. Scherzer emphasized his pride in developing complex sign systems to counter opponents, suggesting PitchCom diminishes this skill-based aspect of the sport. Usability concerns have also emerged, including an initial adjustment period for players unfamiliar with the electronic interface and doubts about its reliability under pressure. Pitchers like noted a slight in operating the device during mound visits, requiring practice to integrate it seamlessly into gameplay. In high-stakes situations, such as or variable field conditions like humid or rainy weather, reports of malfunctions have persisted, including connectivity failures that led to delays or calls, as seen in a 2023 Chicago game involving the Mets. Isolated issues continued into 2024 and 2025, such as occasional audio glitches during games, though MLB's extension of its exclusive agreement with PitchCom through the 2026 season indicates overall confidence in the system's reliability. Crowded stadiums with electronic interference from cell phones and other signals have further compounded reliability issues, raising questions about consistent performance across diverse environments. Some experts and players express mixed views, cautioning that PitchCom's adoption may foster over-reliance on technology at the expense of traditional non-verbal communication skills. This shift could erode players' ability to interpret subtle cues and build intuitive partnerships between catchers and pitchers, as the device standardizes interactions in ways that bypass longstanding interpersonal dynamics.
