Chase Headley exploded in the second half of the 2012 season.

Headley had a .267/.368/.413 line for the first half with eight home runs and 42 RBIs. In August, he hit .306 with 10 home runs and 31 RBIs. A month later, he hit .324 with nine homers and 30 RBIs.

He eventually finished fifth in the NL MVP vote.

"When it started rolling for me at the end of last year, I was going up there expecting I was going to get it done," Headley said.

Headley realizes the bar of expectation has been raised significantly and he embraces that challenge.

"I expect a lot out of myself. And I do think that the norm of my career will be much closer to last season than the years before that," he said. "I feel like I'm closer to being that type of player ... having that success I had last year, gives me a lot of confidence going forward."
