Shota Imanaga Becomes Free Agent After Cubs Decline Option

Left-hander Shota Imanaga is officially a free agent, according to Jesse Rogers of ESPN. The Chicago Cubs have declined their three-year, $57 million club option covering the 2026–2028 seasons. Imanaga, in turn, opted out of his $15 million player option for 2026, making him available on the open market.

The move marks a surprising turn of events for a pitcher who, just a year ago, looked like a foundational piece of Chicago’s rotation. Signed out of Japan before the 2024 MLB season, Imanaga impressed in his debut campaign and appeared poised to anchor the Cubs’ staff for years.

From Sensational Rookie to Struggling Sophomore

When Imanaga joined the Cubs on a deal structured as a four-year, $53 million contract, expectations were moderate. However, he quickly exceeded them. In his 2024 rookie season, the left-hander posted an impressive 2.91 ERA over 29 starts, logging 173 1/3 innings with a 25.1% strikeout rate. His efforts earned him an All-Star selection and a fifth-place finish in NL Cy Young voting — a remarkable debut for a newcomer to MLB.

Yet, 2025 told a very different story. Imanaga began the season with decent results, boasting a 2.82 ERA through eight starts, but advanced metrics told a warning tale. His 4.59 FIP and a reduced 18.8% strikeout rate hinted at regression. A hamstring injury in late spring sidelined him for nearly two months, and when he returned, his inconsistencies only deepened.

Despite flashes of brilliance — such as seven scoreless innings in his first start after the All-Star break — Imanaga’s struggles soon became evident. From late July through the end of the season, he recorded a 5.17 ERA and 5.42 FIP over 12 starts, surrendering 20 home runs in just 69 2/3 innings.

The Home Run Problem and Wrigley’s Role

Home runs became Imanaga’s undoing in 2025. Even during his stellar 2024 campaign, he had a tendency to give up the long ball, finishing with the tenth-most homers allowed among qualified starters. In 2025, that issue worsened dramatically — his 31 home runs allowed were the fourth-most in all of MLB, despite pitching fewer than 145 innings.

Part of this issue might not have been entirely within his control. Wrigley Field, known for its unpredictable wind patterns, shifted from being the fifth-most homer-suppressing park in 2024 to the 11th-friendliest for home run hitters in 2025, according to Statcast. That shift made it even more difficult for fly-ball pitchers like Imanaga to maintain consistency.

Given this context, the Cubs’ decision not to exercise the option appears more strategic than emotional. Committing to Imanaga through his age-34 season would have been a gamble, particularly after such volatility in his performance and environment.

Fan Reaction and the Decline in Form

As late as September, many fans and analysts still believed Imanaga’s rebound potential justified the Cubs exercising their option. In fact, a poll by MLB Trade Rumors on September 10 showed that over 91% of readers felt the Cubs should pick up the deal.

However, Imanaga’s final stretch made that optimism hard to sustain. He posted an 8.04 ERA over his last three regular-season starts and an 8.10 ERA during the postseason. Ultimately, Chicago decided against starting him in the winner-take-all Game 5 of the ALDS against the Brewers, signaling that his stock within the organization had fallen sharply.

What’s Next for Imanaga and the Cubs?

The decision leaves both sides with interesting paths ahead. The Cubs could still extend a Qualifying Offer (QO) to Imanaga, allowing them to either retain him on a one-year deal or receive draft pick compensation if he signs elsewhere. However, that move carries risk — if Imanaga accepts the offer, Chicago would be committing a large one-year salary to a pitcher whose performance trajectory is uncertain.

Meanwhile, the free-agent market for starting pitchers this offseason is deep, featuring several mid-rotation and high-end arms. Teams seeking left-handed depth — especially those in pitcher-friendly ballparks — might view Imanaga as a worthwhile bounce-back candidate. His proven ability to dominate MLB hitters, combined with his strike-throwing consistency, still makes him a valuable target for rotation depth.

Shota Imanaga’s rapid rise and sudden fall with the Chicago Cubs highlight the volatility of pitching in today’s MLB. After dazzling in 2024 and struggling through injuries and home run woes in 2025, Imanaga’s future now depends on whether another club believes it can help him rediscover his All-Star form.

For the Cubs, the decision reflects a desire for flexibility and a chance to retool their rotation. Whether Imanaga returns under a new deal or finds a fresh start elsewhere, his story will remain one of the most intriguing narratives of the 2025-26 MLB offseason.
