SEATTLE -- Chris Capuano was designated for assignment by the Boston Red Sox on Wednesday to clear a spot on the 25-man roster for right-handed starter Clay Buchholz.
Boston made the roster moves before the series finale in Seattle. Buchholz was scheduled to face the Mariners in his first start since May 26 after being on the disabled list with an injured left knee.
Capuano was 1-1 with a 4.55 ERA in 28 relief appearances for Boston this season. He started strong, not allowing a run in his first 12 appearances of the season but struggled recently. In his last five relief appearances, Capuano had given up 10 earned runs, including five to the Mariners in Monday's series opener.
"[Capuano] is a true pro and unfortunately we had to create the spot for Clay and felt like this was the move to make at the time," Boston manager John Farrell said.
Buchholz is 2-4 with a 7.02 ERA in 10 starts this season. He made two rehab starts at Triple-A Pawtucket before rejoining the Red Sox.
Even with designating Capuano, the Red Sox still have a roster imbalance with 13 pitchers and 12 position players. Farrell had hoped that could be solved with the return of outfielder Shane Victorino from the disabled list, possibly as early as this weekend.
But Victorino experienced soreness in his back after last night's rehab stint in the minors and will sit the next few days to rest.
"Our intent is still to get back to 13 position players and we'll look to do that as soon as possible," Farrell said. "That doesn't mean anything is pending by tomorrow or Friday."
Farrell also said that Brandon Workman, Jon Lester and John Lackey would be the starters for this weekend's series in New York against the Yankees and he still plans on trying to get Felix Doubront back in the rotation when Boston returns home to host the Cubs next week.
