The Boston Red Sox's starting rotation has experienced quite a bit of turnover in recent weeks. They added Dustin May into the mix after the trade deadline, but much of the chaos has come from the team's surprise decision to release Walker Buehler.
May made five starts for the Red Sox in August, to the tune of a 5.68 ERA in 25.1 innings, before the team moved him to the bullpen. Buehler was also demoted from the Sox's rotation due to his yearlong struggles (5.40 ERA in 110 innings), but he only made one appearance before his release.
