Zack Greinke's anxiety issues reached a pinnacle seven years ago when he walked away from baseball.

He now has the problem in control and is comfortable on the big stage after signing a huge free agent deal with the Dodgers this winter.

"I don't think about it at all. I don't get stressed by it," Greinke said. "It's just something that was a problem before, but it isn't now. I'm sure it could be somewhere in the future, but it's not anything that affects me."

He nearly left baseball for good when he left spring training with the Royals in 2006.

Greinke managed to handle his rise in fame and the attention that goes with it by taking Zoloft, an antidepressant used by millions of people.

"It wasn't that hard after I got the medicine," he said. "The medicine was the greatest thing ever. I may have gotten lucky and found the right one. The only problem I have with it is that it makes me a little tired, but not real tired. That's the only complaint I have. I know it's not always that easy, but for me it was. I was lucky with that."
