In an exhibition matchup against the Hanshin Tigers, Julian Merryweather showcased his potential by throwing a perfect first inning with just six pitches. After enduring a tumultuous 2024 season plagued by injuries, including shoulder strain and knee tendinitis, Merryweather expressed relief at being healthy and able to focus on his mechanics. The Cubs manager, Craig Counsell, emphasized the importance of Merryweather's performance in 2023, highlighting his reliability in high-leverage situations and the need for him to return to that form.

Catcher Miguel Amaya also expressed excitement over Merryweather's return, indicating his critical role in the bullpen. On the mound, the Cubs used nine pitchers in a strategic approach as they prepare for the regular season opening against the Dodgers. Meanwhile, Colin Rea, who joined the team later, aimed to ramp up his readiness for the season despite limited pitching opportunities in Japan. Porter Hodge is working on improving his splitter, a pitch he aims to integrate into his game this season.
