The Boston Red Sox have made significant roster changes ahead of their matchup with the New York Yankees, including calling up left-handers Bailey Horn and Zach Penrod from Triple-A Worcester and optioning relievers Cam Booser and Zack Kelly back to Worcester. Tanner Houck was scratched from his scheduled start due to shoulder fatigue, with rookie Richard Fitts stepping in. The Red Sox are also experimenting with rookie Ceddanne Rafaela at second base to address defensive issues, while outfielder Roman Anthony has been named the top prospect in Baseball America’s rankings. Other notable prospects include Kristian Campbell, who has impressed in Triple-A, and Wilyer Abreu, praised by manager Alex Cora for his potential Gold Glove-winning defense. Despite mid-season struggles, the team remains hopeful for a playoff push and a stronger performance next season bolstered by their promising farm system.
