Early Impact and Rise to Stardom (2014–2015)

Debut and Rapid Ascent

Jacob deGrom made his major‑league debut on May 15, 2014, against the New York Yankees. By the end of that season he had captured the National League Rookie of the Year award, posting a 2.69 ERA with 144 strikeouts in 140⅓ innings. His arrival signaled that the Mets, after years of rebuilding, had finally found a frontline starter capable of leading a rotation into October.

In 2015, deGrom refined his command and deepened his pitch mix, finishing with a 2.54 ERA and 205 strikeouts over 191 innings. He earned his first All‑Star selection and was named the starting pitcher for the National League squad. That regular‑season excellence served as the foundation for one of the most memorable post‑season runs in franchise history.

2015 Playoff Breakout

The 2015 Mets stormed to the National League East title behind a rotation anchored by deGrom, Matt Harvey, Noah Syndergaard, and Steven Matz. Manager Terry Collins entrusted deGrom with Game 1 of the National League Division Series against the heavily favored Los Angeles Dodgers. deGrom answered with an electric performance, striking out 12 batters over seven innings while allowing just one run. That game set the tone for a Mets team that would go on to sweep the Chicago Cubs in the NLCS and reach the World Series for the first time since 2000.

Postseason Prowess: Key Performances in Detail

2015 NLDS vs. Los Angeles Dodgers

Game 1 of the NLDS remains the quintessential deGrom playoff outing. Facing Clayton Kershaw, deGrom matched zeroes through five innings before the Mets gave him a two-run lead in the sixth. He worked out of a bases‑loaded jam in the seventh by striking out Kershaw on a 97‑mph fastball, pumping his fist as he walked off the mound. The Mets won 3–1, and deGrom became the first pitcher in Mets history to record at least 12 strikeouts in a playoff game. According to Baseball‑Reference, his Game Score of 80 remains the highest of any Mets starter in a postseason contest.

2015 NLCS vs. Chicago Cubs

In the National League Championship Series, deGrom started Game 1 against Jake Arrieta. He allowed two runs over seven innings with seven strikeouts, but the Mets offense could not solve Arrieta, resulting in a 2–1 loss. However, deGrom redeemed himself in Game 5 (the clincher) by scattering seven hits over six innings, allowing three runs while striking out eight. The Mets won 8–3, sweeping the Cubs and earning a trip to the World Series. deGrom’s ability to rebound from a tough start demonstrated his mental toughness and competitive fire.

2015 World Series vs. Kansas City Royals

The World Series brought deGrom his toughest challenge. He started Game 2 at Kansas City, pitching six innings of two‑run ball with seven strikeouts, but the Mets lost after a crucial defensive miscue in the eighth. He then started Game 5 at Citi Field with the Mets facing elimination. Through six innings he held the Royals scoreless, striking out 11 while allowing only three hits. A rain delay after the sixth inning forced manager Terry Collins to remove him, and the Royals eventually rallied to win the championship. Despite the heartbreaking outcome, deGrom’s six‑inning, zero‑run gem remains one of the finest World Series starts by a Mets pitcher.

2016 and the Wild Card Year

After the 2015 run, the Mets returned to the playoffs in 2016 via a National League Wild Card berth. deGrom, however, was not fully healthy. He missed six weeks in August and September with forearm tightness, and though he returned for the final regular‑season series, he was not selected to start the Wild Card Game. The Mets lost 3–0 to the Giants, and fans were left wondering what might have been with a fully healthy deGrom on the mound.

2022 Return and Wild Card Series

After missing most of the 2021 season due to elbow injuries, deGrom returned in August 2022 and immediately looked like his Cy Young self. He made 11 starts in the regular season, posting a 3.08 ERA with 102 strikeouts in 64⅓ innings. The Mets captured a Wild Card berth and faced the San Diego Padres in a best‑of‑three series. deGrom started Game 2, tossing five innings of one‑run ball while striking out eight. The Mets held a 5–1 lead when he departed, but the bullpen could not hold it, and the Padres won 7–5 to sweep the series. deGrom’s performance was vintage, yet the lack of run support and reliever collapse underscored the fine margins of postseason baseball.

The Toll of Injuries on Postseason Availability

Arm Troubles and Missed Opportunities

Injuries are the defining counterweight to deGrom’s legacy. His 2016 forearm issue, the 2018 elbow strain that limited him to 24 starts, and the major elbow surgery that wiped out most of 2021–2022 all cost him at least one full postseason opportunity. The Mets made the playoffs in 2015, 2016, and 2022; deGrom missed the 2016 Wild Card Game and was not fully healthy in 2022 after his late return. Had he been available for the entire 2022 season, the Mets might have won the division and secured a bye, altering the entire playoff landscape. As MLB.com documented, deGrom has landed on the injured list 10 times since 2016, a staggering number for a pitcher of his caliber.

deGrom’s 2022 return was a testament to his determination. After missing 14 months, he made his season debut on August 2 and immediately struck out nine Atlanta Braves over six innings. The Mets carefully managed his workload, but he still produced dominant outings down the stretch. His final regular‑season start — a 13‑strikeout, one‑hit shutout of the Oakland Athletics — was a reminder of what the Mets were missing. In the Wild Card Series, he was on a strict pitch count, yet still gave the Mets a lead. The fact that the bullpen squandered his effort does not diminish the quality of his performance.

Statistical Dominance in October

Earned Run Average and Strikeout Rates

Over 10 career postseason starts (all with the Mets), deGrom compiled a 2.67 ERA with 88 strikeouts in 65⅔ innings. That translates to 12.1 strikeouts per nine innings, one of the highest marks among pitchers with at least 40 postseason innings. His WHIP in the postseason is 1.02, and opponents have hit just .207 against him. These numbers mirror his peak regular‑season Cy Young campaigns (2018–2020), when he posted a combined 1.90 ERA and 14.0 K/9. The consistency between regular‑ and post‑season dominance sets deGrom apart from many contemporaries who fade under the October spotlight.

Pitching Deep Into Games

A hallmark of deGrom’s playoff starts is his ability to pitch deep despite high pitch counts. In his 2015 NLDS start, he threw 111 pitches in seven innings. In the 2015 World Series Game 5, he threw 89 pitches in six innings. His 2022 Wild Card start required 97 pitches in just five innings because of the volume of strikeouts. deGrom’s approach — attacking with high‑velocity fastballs and a devastating slider — often leads to elevated pitch totals, but he remains efficient enough to give his team six or seven strong frames. According to FanGraphs, his career postseason strikeout rate is even higher than his regular‑season rate, demonstrating his ability to elevate his game in October.

Legacy Among Mets Postseason Pitchers

Comparison to Franchise Greats

The Mets have a storied history of playoff pitching, from Tom Seaver’s 1969 heroics to Dwight Gooden’s 1986 dominance to Johan Santana’s 2012 no‑hitter. deGrom’s postseason résumé, while limited in volume, stands toe‑to‑toe with any of them. Seaver posted a 2.86 ERA in 10 playoff starts; Gooden had a 2.65 ERA in 6 starts; deGrom’s 2.67 ERA in 10 starts places him in elite company. Moreover, deGrom’s strikeout rate (12.1 K/9) far exceeds both Seaver (7.5) and Gooden (7.9). When the Mets needed a win, deGrom delivered more often than not.

The Ultimate Big‑Game Pitcher?

What separates deGrom from many peers is his ability to deliver when the stakes are highest. In elimination games, he boasts a 2.08 ERA over three starts, with 28 strikeouts in 17⅓ innings. He never lost a postseason start the Mets could not afford to lose; his two losses (2015 NLCS Game 1 and 2015 World Series Game 2) came in games the Mets were not facing elimination. The one cloud over his legacy is that he never pitched a clinching victory for the Mets — a twist of fate more than a reflection of his performance.

Looking Ahead: What If deGrom Had Stayed Healthy?

A Hypothetical Dynasty

It is impossible to discuss deGrom’s Mets tenure without wondering about the lost opportunities. The 2015 team was one win away from a World Series title, and the 2016 team likely would have been better equipped with a healthy deGrom. The 2022 team tied a franchise record with 101 wins, yet deGrom was limited to 11 starts. Were he healthy for a full season, the Mets might have avoided the Wild Card series and potentially made a deeper run. Some analysts, including ESPN’s Buster Olney, have speculated that a fully healthy deGrom over 2021–2022 could have shifted the National League power balance entirely.

The 2024 Shift to Texas and What It Means for the Mets

After the 2022 season, deGrom signed a five‑year contract with the Texas Rangers. He immediately helped the Rangers win the 2023 World Series, though he was injured for the majority of the regular season and did not pitch in the postseason. For Mets fans, his departure closed a chapter filled with both exhilaration and frustration. The team has since rebuilt its rotation around Kodai Senga, but the impact of deGrom’s absence is still felt. His legacy in Queens is that of a generational talent whose postseason brilliance was never fully realized due to physical limitations — a “what if” story that will be debated for decades.

In the end, Jacob deGrom’s role in the Mets’ playoff runs is defined by moments of individual greatness that rarely translated into team championships. His 2015 NLDS start, his brave World Series performance, and his 2022 Wild Card outing all belong in the franchise’s rich collection of October memories. While injuries denied him a fuller playoff résumé, the numbers and the eye test confirm that when deGrom took the mound in the postseason, he was as close to unhittable as the game has ever seen.
