Jason Bay is fighting the temptation to tinker with his mechanics the same way a person on a diet might reach for willpower to avoid an open box of doughnuts.

The Mets left fielder said he is winning the mental battle, but a few results certainly might help diminish his chances of falling into relapse.

"I'm not cheating or anything," Bay said yesterday. "There are times when you feel good and then you don't and say, 'Here's what I need to change.' But don't change anything — it's part of the process. I've had to fight that a little bit, but it's kind of human nature."
