SAN FRANCISCO -- Rockies right-hander Alex White, who has shown quality stuff at times but has not pitched as many as five innings in any of his last nine starts, will move to the bullpen to make room for left-hander Jorge De La Rosa. The Rockies will start De La Rosa -- out since May 2011 because of Tommy John left elbow surgery -- on Thursday against the Giants. Manager Jim Tracy said he hopes White uses the bullpen experience to jump-start himself on the road to efficiency. Tracy said the Rockies haven't given up on White (2-8, 5.15 ERA) as a starter. "I don't want Alex White to sit and feel he's the guy that's being singled out -- we want to teach all the guys the importance of efficiency," Tracy said. "Hopefully, this will end up being a very worthwhile thing.
"In a perfect world, I want him to be one of our starters that become much more efficient, with the type of stuff that he has, the effectiveness that he has with his sinker and how good he can be."
