Kendrys Morales has elected to undergo a second surgery on the left ankle he broke last May 29, a procedure that will sideline the Angels first baseman for the entire 2011 season.

"It's definitely a challenge for us not having Kendry in the middle of our lineup; it's a significant blow," Angels General Manager Tony Reagins said. "But having gone through most of last season without him, the team has learned how to deal with it and move forward. We've had adversity before, and we will have it again."

The procedure, to be performed by Dr. Thomas Clanton, a Colorado foot-and-ankle specialist at a date that hasn't been determined, will be to clean up scar tissue and remove several degenerative cysts that have developed in the joint.

"The fracture has healed completely, but these are the consequences of a devastating injury," said Dr. Lewis Yocum, team physician. "One option was to continue the conservative course with therapy and rehabilitation, but we're trying to gear him up for next season."

Yocum said the second procedure will require a minimum of six months for recovery.
