Cards put Linebrink on DL; activate Marte

MILWAUKEE -- The Cardinals have placed reliever Scott Linebrink on the disabled list with right shoulder capsulitis, more commonly known as frozen shoulder. The move is retroactive to March 30, and St. Louis has purchased the contract of right-hander Victor Marte, who will take Linebrink's 'pen spot.

Shoulder capsulitis surfaces as the result of inflammation, scarring, thickening and shrinkage of the joint capsule, according to various medical websites. It also limits range of motion. Linebrink did not pitch in the club's season opener on Wednesday.

There is not a definitive timetable on when Linebrink is expected to return, though there is possibility that his absence could span as little as two weeks. An MRI taken on Thursday revealed no structural damage. Rest is the prescribed remedy, and general manager John Mozeliak said that Linebrink could begin more rigorous physical therapy next week.

Linebrink will remain in St. Louis, which is where he went to be examined.

Mozeliak confirmed that Linebrink first alerted staff that his shoulder felt tight following his March 29 Grapefruit League appearance. That outing came the day after Linebrink was told that the Cardinals would be adding him to their 25-man roster. Linebrink entered camp as a non-roster invitee, under a Minor League deal.

He made 10 spring appearances, logging 10 2/3 innings and allowing just two earned runs. Marte's spring numbers were similar. In 10 Grapefruit League innings, Marte allowed one earned run on six hits and three walks. He struck out seven, and was the final pitcher sent out from Major League camp.

The Cardinals' decision to summon Marte was partially the result of those strong spring results, but also influenced by the season he had with Triple-A last year. In 55 appearances with Memphis, Marte saved 31 games and posted a 1.44 ERA.

"We were tempted to bring him up last September, but the problem was I just didn't think we could get him very many innings, given where we were and what was occurring at the time," Mozeliak said. "It's nice that he can be rewarded after the spring that he had. It's very deserving."

Marte's last big league appearance came in 2010, when he was with the Royals. From 2009-10, he made 30 relief appearances for Kansas City, posting a 9.30 ERA in those 39 2/3 innings.

With the addition of Marte, the Cardinals' 40-man roster is again full.
