Tommy John, Four-Time All-Star and Surgical Pioneer, Dies at 83

What happened: Tommy John, the four-time All-Star pitcher whose name became attached to ligament-replacement elbow surgery, has died at 83. The Guardian reports that TMZ said John died at his Florida home with family around him, including his wife, Cheryl, after recently receiving hospice care.

Watch the highlights:

Why it matters: John's playing career and medical history became inseparable after an elbow injury threatened to end his time in the major leagues. The New York Yankees remembered him both as a central member of their rotation and as an athletic and medical pioneer whose recovery influenced the paths available to later injured players.

John was 31 when he tore the ulnar collateral ligament in his pitching elbow in 1974. Dodgers team physician Dr Frank Jobe replaced the damaged ligament with a tendon from John's right forearm, giving the procedure estimated odds of success of 100 to one. John missed the 1975 season but returned in 1976 and pitched for another 14 seasons.

The left-hander had compiled a 124-106 record with a 2.97 earned-run average across 355 appearances, including 318 starts, during his first 12 major league seasons. After surgery, he went 164-125 with a 3.66 ERA in 405 appearances and 382 starts. His full career lasted 26 seasons and included time with six clubs, among them the Chicago White Sox, Los Angeles Dodgers and Yankees.

Medical impact: The procedure became widely known as Tommy John surgery and offered pitchers a route back from an injury that had previously been considered career-ending. The Guardian cited American Medical Association data saying about 35% of active major league pitchers in 2024 had undergone it, including Cy Young winners Jacob deGrom, Chris Sale, Justin Verlander and Tarik Skubal.

John had recently undergone treatment connected to a recurrence of bladder cancer and issued a farewell letter to fans earlier this month. He thanked Jobe for saving his arm and acknowledged the many careers later extended by the operation. John and his family also expressed concern about the procedure's use among young athletes. After retiring as a player, he worked as a broadcaster for the Minnesota Twins and Yankees; he was not elected to baseball's Hall of Fame.
