SEATTLE — Mariners' Gold Glove third baseman Adrian Beltre had surgery today to repair a ligament in his left thumb and remove bone spurs from his left — or non-throwing — shoulder.

Mariners' medical director Dr. Edward Khalfayan performed the shoulder surgery Thursday and then assisted in the thumb procedure.

The doctor said both were successful and he expects Beltre to need three to four months of rehabilitation.

Beltre decided last week to have the operations before the end of the regular season to make sure he was healthy for the start of 2009. He finished his season hitting .266 with 29 doubles, 25 homers and 77 RBIs.
