Nobody understands how pesky and intrusive finger blisters can be more than Tim Lincecum, who has had more than his share. He has one now and wants to get rid of it before it really hampers his ability to pitch.

To that end, Lincecum skipped what would have been his second Cactus League start on Saturday. Yusmeiro Petit faced the Cubs instead.

"It's not too terrible," Lincecum said. "It's just hot and sensitive like it gets here (in Arizona). I'll just play it day by day and see how it feels. I don't want to complicate the issue and make it worse. I don't want it to be anything that will keep me from the season."

Lincecum's blister grew along the edge of his fingernail. It sounds benign within the universe of ailments a pitcher can have, but a blister can be painful and difficult to fix when having to pitch a lot. A blister derailed Santiago Casilla's run as closer last summer.

Lincecum said his blisters hamper his curveball and slider.

He had one throughout spring training in 2009. Reminded that he won a Cy Young that season, Lincecum smiled and said, "I did, didn't I?"
