The Boston Red Sox are moving Walker Buehler to the bullpen, manager Alex Cora said before the team's Friday night game against the Yankees in New York.
Buehler, signed to a one-year, $21.05 million contract this offseason, has a 5.40 ERA in 22 starts this season.
The right-hander failed to make it to the fifth inning in his latest start, allowing two runs on four hits while walking four in four innings before getting pulled by Cora.
Buehler, speaking after the loss to the Baltimore Orioles, said the early hook was warranted.
