Philadelphia Phillies right-hander Roy Halladay credits Harvey Dorfman, the late, famed sports psychologist, for much of his success as a pitcher.

After he compiled a 14.73 ERA in his first two starts, Halladay went back to old e-mail conversations with Dorfman.

He is 2-0 with a 1.71 ERA in his last three starts as he gets set to face the Indians on Tuesday night at Progressive Field.

Halladay has credited an improved outlook for much of the turnaround.

"It's a way of looking at a game," he said. "It's not a mental thing. It's how you approach the game. I think coming out of Spring Training, having short outings, having some poor outings, coming back wanting to prove that I was healthy, my focus wasn't on making pitches. My focus was on trying to prove something that necessarily didn't need to be proven. So I just tried to readjust and get back to having my focus on singular pitches and working counts and simplifying. That has always been my bread and butter, and for some reason, I got away from that. I think just coming off the injuries that I had [in 2012], obviously, being under a microscope and a lot of questions being asked, I let that kind of divert my attention. Just getting back to really simplifying is what I always tried to do.

"And I feel like that's what helped me get back to where I need to be."
