Veteran pitcher Zac Gallen is set to return to the Arizona Diamondbacks for the 2026 season, agreeing to a one-year contract worth $22 million, which matches the qualifying offer he had previously declined. The deal was finalized in Phoenix and marks Gallen’s return to the team he has been primarily associated with since 2019, confirming multiple reports including those from Ken Rosenthal of The Athletic.
Contract Details and Negotiation Background
Initially pursuing a multi-year deal through his agent, Scott Boras, Gallen ultimately accepted the qualifying offer after no satisfactory long-term agreement emerged. MLB.com had earlier indicated that the Diamondbacks and Gallen were nearing a final arrangement before the confirmation. This contract reflects the precise amount of the qualifying offer, valued at $22.025 million.

Career Highlights and Recent Performance
Since being traded to Arizona in 2019, the 30-year-old right-hander has anchored the Diamondbacks’ pitching staff. In 2022, Gallen posted a 12-4 record with a 2.54 ERA and finished fifth in the National League Cy Young Award voting. The following year, he played a key role in leading the Diamondbacks to their first World Series appearance since 2001, delivering six no-hit innings in Game 5. Despite the team’s loss in the series, he was named an MLB All-Star and finished third in NL Cy Young balloting.
From 2023 through 2025, Gallen was the team’s Opening Day starter. However, last season was among his more challenging, as he finished with a 13-15 record and career highs with a 4.83 ERA along with a lower strikeout rate of 8.2 per nine innings. Nevertheless, Gallen showed resilience during Arizona’s late-season push for the playoffs, recording eight quality starts in his last 11 appearances with a 3.32 ERA across his final 65 innings. Ultimately, the Diamondbacks narrowly missed securing a Wild Card berth.
Background and Career Summary
Drafted by the St. Louis Cardinals in the third round of the 2016 MLB Draft after playing college baseball at North Carolina, Gallen was traded to the Miami Marlins in 2017. He made his major league debut with Miami in 2019 before being dealt to Arizona in a trade that sent Jazz Chisholm Jr. to the Marlins. Over his seven-season MLB career, Gallen has compiled a 66-52 record alongside a 3.58 ERA, establishing himself as a consistent presence on the mound.
Looking Ahead for Gallen and the Diamondbacks
Gallen’s decision to rejoin the Diamondbacks on a qualifying offer sets the stage for a pivotal 2026 campaign, where he will aim to rebound from last year’s struggles and help Arizona contend once again. The deal reflects both the team’s confidence in his abilities and his commitment to contributing to their future success. Fans and analysts will be watching closely to see if Gallen can regain his peak form and propel the Diamondbacks back into postseason contention.
