This will draw me out on the dance floor after being a wallflower for 5 years. I think Heyward will bounce back at the plate this year. First, he almost has to- he could hardly have a worse year than last season. But, I also think the changes in his swing mechanics were absolutely necessary for him to be more productive. The following is my opinion, based on my personal understanding of a good, fundamental baseball swing. (If you want to skip the rest, just know that I think he will be quicker to the ball and actually be able to hit for more power this year) There are two main camps of hitting mechanics instruction. They are rotational and linear. Some popular proponents of each believe that the other is totally wrong. However, the best hitting coaches use components of both hitting philosophies and don't try to put every athlete into the same cookie-cutter methodology. Heyward, according to what I've seen on video, has always be a very rotational hitter. That's not always a bad thing. Ted Williams was a pretty decent hitter, and he is a rotational poster boy. But it looks like, especially this past season, Heyward got "too rotational". The Sean Casey analysis was very good- Heyward hardly off got off his backside last year and to compensate, sped up his hands. If you rotate too much on your backside, you lose power. You can also end up with a longer path to contact. Heyward's swing last year was very long to the ball and short through it. You want the opposite. And that's what it looks like he's working on in these new videos. Like Casey said, he's now making a bit of a linear (Casey didn't use that word, but that's what he's doing) move toward the pitcher and getting off his back side. Now, he still needs to keep his head behind the ball and rotate against his front leg, and his changes seem to be helping him with that. In other words, you can't ONLY laterally shift your weight, you still rotate. Again, I agree with what Casey said in his video, and I think this change will give him more power. Power that he should have, since he is built like Jack Reacher (book version, not Tom Cruise) The other thing his new swing has that's different is a quicker path to the ball. Casey didn't mention this, but I'm sure he'd agree with me (haha). Last year, Heyward let the bat wrap back around his head during his load. This meant he had to swing it way back around to get to contact. Sometimes players will do this in a misguided attempt to get more power. He's now (at least in that workout video) keeping the barrel more upright during his load and therefore will have a much quicker and shorter swing to the ball, as well as being longer through the zone, as his extension should now come after contact, whereas before he'd sometimes be fully extended at contact with the ball, which is a much weaker position. The other benefit of being quick to the ball is that you have an additional couple of split seconds to judge a pitch. Doesn't sound like much, but for these guys, that's gold, both with pitch recognition and having power to all fields because you can "let it travel" a little deeper. There you have it. He can print this out and put it next to his comeback player of the year award in 8 months.
