New York Mets infielder and outfielder Jeff McNeil underwent a procedure to address thoracic outlet syndrome (TOS) shortly after the 2025 season, according to his agent, Garrett Parcell, as reported by Joel Sherman of the New York Post. The operation, described as minor, targets a condition that can cause shoulder and arm discomfort, more commonly seen in pitchers but not unheard of among position players like McNeil.
Thoracic outlet syndrome involves compression of nerves or blood vessels between the collarbone and first rib, often leading to pain, numbness, or weakness in the affected arm. For McNeil, a right-handed thrower and left-handed batter, the procedure likely addressed issues in his right shoulder, though specific details were not disclosed. The surgery comes after a 2025 season where McNeil battled multiple injuries, including a fractured right wrist and a low-grade right oblique strain, which sidelined him for significant periods.
Despite these setbacks, McNeil, a two-time All-Star, showed resilience in 2025, posting a .259/.351/.444 slash line with 10 home runs and a 127 OPS+ in 90 games, his best offensive output since his 2022 batting title season. However, his performance dipped late in the year, with a .125/.211/.172 line over his final 71 plate appearances, possibly hinting at the TOS-related discomfort.
The procedure offers hope for a full recovery, with examples like pitcher Merrill Kelly, who returned to form after a similar operation in 2020. McNeil, who turns 34 in April 2026, is expected to be ready for spring training, aiming to anchor second base or the outfield in the final guaranteed year of his four-year, $50 million contract. The Mets, coming off a competitive 2025, will rely on McNeil’s versatility and bat-to-ball skills as they push for a postseason return.
McNeil’s camp remains optimistic, with no reported concerns about his spring training timeline. Mets fans will be eager to see their “Squirrel” back at full strength, scampering across the diamond in 2026.
