The Boston Red Sox are making critical adjustments to their pitching roster, designating Joely Rodriguez for assignment and calling up Brad Keller ahead of a crucial series against the Toronto Blue Jays. This move comes as the team struggles with a depleted pitching staff, exacerbated by a challenging sweep by the Arizona Diamondbacks. Manager Alex Cora and chief baseball officer Craig Breslow are also looking to the future, potentially targeting high-profile acquisitions like Japanese phenom Rōki Sasaki to bolster the rotation. Meanwhile, the Red Sox face a pivotal period, with their playoff hopes diminishing due to a historically poor post-All-Star break performance. To address immediate needs, the team may call up Quinn Priester from Triple-A Worcester for the upcoming games. August remains a critical juncture for the team, with injuries and fatigue contributing to their recent downturn.
