Thanks to Lance McAlister’s site, this is from Baseball Prospectus:

On his hitting:

    DL: You’ve reportedly made mechanical adjustments to help improve your timing. Can you elaborate on what those adjustments were?

    CH: I just concentrated on getting myself in a position to hit a lot earlier than I used to. I used to have a wide stance where I kind of tried to get a load going before the pitch and a lot of times my front foot wasn’t getting down on time. So, what I essentially did was kind of just pre-set. I start off standing pretty much straight up and then I kind of sink into it. That’s pretty early, and then I just kind of wait there a little bit and get a little rhythm with my hands and my lower body. I stride a tiny bit, but it’s almost a no-stride swing.

    DL: Has that impacted your power in any way?

    CH: No, in fact…I guess, maybe. I possibly don’t hit the ball quite as far, but power came from making more solid contact this year. In years past, I’d hit a lot of balls off the end of the bat, or I’d get jammed a lot, just because of my timing. This year I was able to make a lot more solid contact, which translated into more power.

    DL: Was the adjustment suggested by one of your hitting coaches?

    CH: Our minor league hitting coordinator is Ronnie Ortegon, and he worked a lot with me in spring training. He and I get along well and he always kept telling me, “Your timing is late, your timing is late,” and it was getting kind of frustrating because I didn’t feel that to be the case. But he was persistent. He kept staying on me and with about three games left in spring training I kind of just moved to the opposite end and made my timing so early that it couldn’t be late. I started having some success, and I hadn’t been having hardly any that spring training, so I’m thankful that he kept pushing me and pushing me to make some changes in my timing. So far it has worked out.

    DL: Has the adjustment helped you to do a better job of using the whole field?

    CH: Yes, although I’m still generally more of a pull hitter. I don’t spread the ball around as much as maybe I’d like to, but what has really translated is hitting right-handers and their breaking balls. Up until this past year, I really hadn’t done a whole lot with right-handed sliders and curveballs, and probably half of my home runs this season were on right-handed breaking balls. That solely comes from my timing and being able to stay back. That’s been the biggest thing with the adjustment – being able to hit right-handed pitchers.

    DL: Do you pay more attention to your batting average or your on-base percentage?

    CH: I would say on base percentage for sure. It’s more important. Getting on base is the whole point of the game, because that’s how you end up scoring runs, so I’d like to increase my walk numbers a little bit. But while I’d like to walk more than I do, at the same time I like to stay aggressive. I’ll still swing early in the count, because usually that’s when you get a good fastball to hit. I think there’s a fine line between walking a lot and not being aggressive enough, so I like to balance those two out.

On his defense:

    DL: Where is your defensive game right now?

    CH: I think it’s pretty good. My arm has gotten a lot better since I was drafted, and I feel like my range is just as good as it has always been. I’m still working on taking the best routes that I can to the ball.

    DL: Do you see yourself as primarily a corner outfielder?

    CH: No, I think that I can play center field as well as a lot of guys can. I played that in college and I’ve played a lot of center field in the minor leagues, and I definitely take pride in the fact that I can play all three outfield positions. Drew can play center field really well, though, so I’ll play wherever they put me.

Pretty good interview, give it a read.
