Chicago Cubs first baseman Derrek Lee left Monday’s game because of pain and inflammation in his right thumb. Lee grimaced after he singled in the third inning, and again after he singled in the fourth, and Xavier Nady was called on to replace Lee at first.

The first baseman has been bothered by the thumb since he jammed it sliding into second base and is being considered day-to-day at this point.

Lee is hitting .316 over the Cubs first six games with 1 HR and 3 RBIs. You can see Lee’s statistics here.
