Colorado Rockies pitcher Kip Wells has gone from being a starting rotation hopeful, to the bullpen, to the sidelines.

The right-hander will be out of the Rockies lineup for the foreseeable future following surgery Tuesday for a blood clot in his right hand.

Wells, 31, was placed on the 15-day disabled list Monday, effective April 28.

He was 1-1 with a 2.29 earned-run average in 10 games and one start.

On March 6, 2006, Wells, then with the Pittsburgh Pirates, underwent surgery to repair a blocked artery in his right arm.

In 2004, Wells had carpal tunnel release surgery by a hand specialist at Allegheny General Hospital in Pittsburgh.

The Rockies gave Wells a $3.1-million contract during the off-season, hoping he would compete for a spot in the starting rotation.

However, inconsistency in spring training landed him in the bullpen.

Wells is 1-1 with a 2.29 ERA in 10 games (one start) this season. He last pitched April 28 in the Rockies' 4-0 loss to the hometown San Francisco Giants.

He threw eight of his nine pitches for balls and walked in two runs.
