Rockies place Corpas on 15-day DL

Veteran right-hander Rincon called up from Triple-A

DENVER -- At least one bone chip in the right elbow forced Rockies setup man Manuel Corpas to the 15-day disabled list on Saturday. Veteran righty reliever Juan Rincon will have his contract purchased from Triple-A Colorado Springs to replace Corpas.

Rincon was with the Colorado Springs club in Fresno, Calif., so it's uncertain if he will be available for Saturday night's game with the Pirates at Coors Field.

The chip was discovered Friday after Corpas woke up with swelling and limited motion after pitching the previous two days. Corpas received a cortisone shot Friday, and the Rockies planned to see if the area improved in two days. That turned out to be too narrow of a window.

"We thought it might be better in a few days, but I don't think so," Corpas said Saturday. "So they put me on the disabled list."

Corpas, who said he believes there are not multiple chips, said the best-case scenario is he'll be able to play light catch after a few days' rest, then work his way up to a rehab assignment with Colorado Springs.

Bone chips, often referred to as "loose bodies," often are present in a pitcher's arm. But it's when they cause swelling or float into a join that they become a problem. The problem the Rockies discovered in Corpas was not in a joint.

Corpas said his dream sequence ends with him being able to finish the season pitching effectively and then having any loose bodies removed during the offseason. He had thrown scoreless ball in eight of his last 10 outings, and his last two appearances arguably were his crispest of the season.

Righty reliever Matt Daley likely will slide into Corpas' eighth-inning role, but righty Joel Peralta and lefties Alan Embree and Randy Flores can perform matchups, manager Jim Tracy said.

Rincon, 30, has appeared in nine Major League seasons, mostly with the Twins, and he is 32-27 with a 3.84 ERA and three saves in 416 games -- all but three in relief. Rincon began this season with the Tigers, and he went 1-0 with a 5.23 ERA in seven games before being designated for assignment to make room for starter Dontrelle Willis.

After joining the Rockies organization, Rincon went 1-0 with a 1.84 ERA and three saves at Colorado Springs. Rincon has eight strikeouts and three walks in 8 2/3 innings.
