Buchholz was placed on the disabled list May 28 after he hyperextended his knee during a start against the Atlanta Braves on May 26. He’s 2-4 with a 7.02 ERA in 10 starts this season.
To make roster room for Buchholz, the Red Sox designated reliever Chris Capuano for assignment. Capuano started the season strong, not allowing a run in his first 12 appearances, but the left-hander has struggled of late. He gave up five earned runs in his last relief appearance, raising his ERA to 4.55.
