Ahead of Tuesday night’s game with the visiting Los Angeles Angels, the Red Sox made another slew of changes to the pitching staff.

One week after reinstating Richard Fitts from the 15-day injured list on May 27, the Red Sox optioned the right-hander to Triple-A.

The Red Sox also placed Nick Burdi on the 15-day injured-list with a right-foot contusion.

To fill their spots on the pitching staff, the Red Sox recalled righty reliever Zack Kelly, whom they’d previously sent back to Worcester when Fitts returned from his injury, and fellow righty Cooper Criswell.

The moves come two days after the club placed Justin Slaten, one of their key bullpen arms, on the 15-day injured list with right shoulder inflammation and recalled Luis Guerrero from Triple-A.
