PHOENIX -- A.J. Griffin hasn't changed much about the way he throws from last year to this.
The mental part of the game, though -- that's changing.
Griffin led the major leagues by giving up 36 home runs last year. Toward the end of the season, it was all anybody, particularly the media, wanted to talk about.
They didn't want to talk about his excellent .226 batting average against, 30 points under the league average. They wanted to talk about all those bombs. Griffin now says he bought into it.
And that was a mistake.
"I put too much thought into those questions,'' Griffin said Saturday as the team went through its annual photo day. "I should have tuned it out, but I didn't.
"All that talk made me think about it, and that was a mistake.''
Griffin was the toughest of the A's regular starting pitchers to get a hit against. He led the team with a career-best 200 innings. His ERA of 3.83, while up from his rookie mark of 3.06, was under the median of A.L. pitchers.
And his total of 14 wins is the most any member of the 2014 staff had last year.
So pardon Griffin if he doesn't feel like changing the way he pitches and focuses instead on the mental part of the game.
"I learned from my struggles last year,'' he said. "I've been pretty good at executing pitches. What got me in trouble was that one time or two times a game a ball would go out. I've always been focused when I'm pitching. But I've got to be ultra-focused.
"It's not like I was giving away pitches before. But I have to make sure that I don't give anything away. Then the home runs will take care of themselves.''
Manager Bob Melvin said while Griffin, 26, did have issues with homers, it's the other statistics, particularly the win total and the innings pitched total, that need to looked at.
"At the end of the day, he's a good starting pitcher,'' Melvin said. "The one blip was the home runs. But he realizes why they happened.
"His mindset has to be that he's not a guy who gives up homers. If he gets there, he won't. They can become a self-fulfilling prophecy. It's like a hitter who goes 0 for 15. Getting back on track just becomes harder as you go along.''
Having the stats sheets zeroed out at the beginning of the season gives a chance for a fresh start. And Griffin will take full advantage to get back to full enjoyment of the game he loves.
"I do love baseball,'' he said. "But it takes focus to play the game and patience to see it through. You have to have dedication to love it.''
Despite allowing a major-league-high 36 home runs last season, A.J. Griffin was one of the A's most consistent starters. Here's a look at the 2013 statistics for the returning and acquired A's starting pitchers:
