Brock Stewart, reliever for the Minnesota Twins, will start the season on the 15-day injured list as he recovers from shoulder surgery and addresses a sore hamstring. After throwing around 20 pitches in a minor league game, the team anticipates a return by mid-April. Stewart's spring training was delayed due to his surgery last August, and he experienced a setback with the hamstring injury. As Stewart recovers, the Twins face a challenge in their bullpen, with other pitchers like Michael Tonkin also on the injured list. The team has several candidates for the remaining bullpen spot, including Eiberson Castellano and Scott Blewett. Meanwhile, Brooks Lee is also dealing with back tightness, which could impact his roster position.
