Jacob deGrom’s season‑ending injury on July 30, 2021, turned the New York Mets from a dominant NL East contender into a team scrambling to avoid a losing record. The right‑hander’s abrupt exit after a 10‑0 start to the season left a void that the club never managed to fill, and the fallout still echoes in franchise decisions today.
What happened?
DeGrom, fresh off a 2.43 ERA and 13 wins, was placed on the 60‑day injured list after a forearm strain was diagnosed during a routine check on July 30, 2021. The Mets, sitting 56‑38 and five games ahead of the Atlanta Braves, lost their ace and saw the bullpen stretched thin. In the next 30 games, New York went 12‑18, dropping to 68‑56 and slipping to third place. The collapse culminated in a 100‑62 finish, missing the postseason for the first time since 2016.
Why it mattered for Jacob deGrom and the Mets
DeGrom’s injury exposed the Mets’ over‑reliance on his dominance. Without his 9.6 K/9 rate, the staff’s ERA ballooned from 3.20 to 4.55 in the final stretch. The front office, forced to act, traded veteran reliever Edwin Díaz to the Seattle Mariners in early August, a move that sparked fan outrage. The loss also accelerated the trade deadline scramble that saw the Mets acquire shortstop Javier Báez and outfielder Starling Marte, both of whom struggled to produce.
For deGrom, the setback marked the beginning of a string of health concerns that would define the next few seasons. The forearm strain was later linked to an elbow issue that required surgery in 2022, limiting his availability and prompting speculation about his long‑term role with the franchise.
How the collapse reshaped the franchise
The Mets’ late‑season slide forced a reevaluation of roster construction. General manager Jared Porter, who had overseen the 2021 signings, was dismissed in November 2021. His replacement, Billy Eppler, shifted focus toward building depth rather than banking on a single ace. The team’s payroll strategy changed, emphasizing versatile arms and defensive upgrades.
The collapse also impacted fan sentiment. Attendance dipped by 12% in the final two months of the season, and season ticket renewals fell short of expectations. The organization responded with a marketing push centered on “New York’s Next Era,” highlighting young talent like Francisco Lindor and Pete Alonso.
What comes next for Jacob deGrom?
After missing the entire 2022 season, deGrom returned in 2023 with a modified pitching motion, posting a 2.85 ERA over 28 starts before another elbow issue landed him on the IL in September. The Mets have now committed to a five‑year, $200 million extension, signaling confidence that he can regain his 2021 form.
The 2021 injury remains a cautionary tale for New York: an elite pitcher can’t carry a team alone. As the Mets look to build a deeper roster, deGrom’s health will continue to be the linchpin of any postseason hopes.
Jacob deGrom’s 2021 injury didn’t just end a season; it reshaped an entire franchise’s trajectory.
