The team deciding against picking up Imanaga's three-year option triggered a $15.25 million player option, which the pitcher also declined, making Imanaga a free agent. It's unclear whether the Cubs intend to make the southpaw a one-year, $22.025 million qualifying offer. Imanaga held a 4.70 second-half ERA and 8.10 ERA in two postseason starts, and his strikeout rate dipped to 20.6 percent in 2025. However, with a 3.28 ERA, 1.00 WHIP and 291:54 K:BB over 318 regular-season innings since the beginning of the 2024 campaign, Imanaga will draw plenty of interest on the free-agent market.
