DENVER -- The Rockies' 8-6 loss on Tuesday due to a blown save by closer Manuel Corpas has started to become an unfortunately familiar theme of late.
Entering the season, the closer's role appeared to be a sure thing. Corpas took over for Brian Fuentes last season and converted 19 of 22 saves. In the postseason, he converted five of six saves and had a 0.87 ERA.
In 2008, Corpas has already blown three saves in seven opportunities, and after giving up three runs Tuesday, his ERA ballooned to 6.55. With Fuentes off to a solid start, Corpas' role has come into question.
"That's not a percentage we're going to continue to deal with," Clint Hurdle said. "That's the reality of it. But do I expect him to convert every other one? No, I don't. If he gets to the point where he's not closing off games with the success we think he should and we need him to, then we'll probably make a change."
Last season, Corpas had success by keeping the ball down and working the corners. This season, his command has not been the same and he's leaving the ball over the plate, as he did Tuesday night.
"Missing location -- I think that would be the more specific cause and effect of what's going on with command," Hurdle said. "More often than not his ball ends up down low. It's down but not where he wanted it down."
