The Boston Red Sox made a roster move to activate starter Brayan Bello by demoting reliever Zack Kelly, who had struggled with a 9.00 ERA in seven appearances, including a rough outing against the White Sox where he hit two batters. Manager Alex Cora remains optimistic about Kelly’s future, expressing that he believes Kelly has the potential to become a key reliever for a championship team, albeit with a focus on consistency. Cora suggested that Kelly might need to simplify his pitch mix while at Worcester to improve his performance. The decision to retain Josh Winckowski, who has shown the ability to pitch multiple innings, also reflects the team's strategy to bolster its bullpen.
