SEATTLE — Chis 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 tomorow 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.

Curt Schilling says his cancer is in remission

PROVIDENCE, R.I. — Curt Schilling, the former Boston Red Sox pitcher turned ESPN television analyst, said Wednesday his cancer is in remission.

Schilling announced the news on social media and thanked his Boston-based medical team.

He revealed his diagnosis in February, saying he planned to “embrace this fight, just like the rest of them, with resolute faith, and head on.” He hasn’t indicated the type of cancer or his prognosis, but has posted pictures of himself undergoing treatments.

Schilling is a three-time World Series champion — with the Arizona Diamondbacks in 2001 and the Red Sox in 2004 and 2007. In 20 seasons, he was 216-146 with a 3.46 ERA. The right-hander shared the 2001 World Series MVP award with left-hander and teammate Randy Johnson.

After pitching in the 2007 World Series, Schilling suffered reversals on and off the field. His 2-1 victory in Game 2 of Boston’s four-game sweep of the Colorado Rockies was his last game.

He spent the entire 2008 season on the disabled list after right shoulder surgery and retired in March 2009. He started an ill-fated video game company, 38 Studios, and later said he invested and lost as much as $50 million. Its collapse is the subject of a lawsuit in Rhode Island after it got a $75 million state-guaranteed loan.

On Feb. 5, Schilling announced in a statement issued by ESPN that he was diagnosed with cancer.

“With my incredibly talented medical team I’m ready to try and win another big game,” the statement said.

On May 28, Schilling received a loud ovation from Fenway Park fans during a pregame ceremony honoring members of the 2004 team that won the Red Sox first championship in 86 years. Like the other players, he walked in from the left-field wall. His son Gehrig was by his side.
