Outfielder Michael Morse who finished the season hitless in his last 10 games with the Orioles will undergo surgery Wednesday to fix a bone outgrowth in his left wrist according to an industry source.

Dr. Richard Berger of the Mayo Clinic in Minnesota will perform the arthroscopic surgery which will shave the bone. The source said Morse should be able to begin using the wrist again in four weeks and should be back to baseball activities in six to eight weeks so the pending free agent should be a full go by the start of spring training.

Doctors estimated that the outgrowth of the capitate bone that runs down through the hand was caused by trauma and probably occurred sometime in May which likely affected his power and extension during his swing.
