Hey, maybe you can actually start judging a swing now! Honestly, I'm no swing doctor or expert either. I talked to one person who used to be a scout, and he thinks it's partly mental and that Heyward is thinking too much. Not just letting instinct take over. Hitting has to come naturally, and you have to be relaxed at the plate. He doesn't think Heyward is comfortable in the batter's box. He thinks Heyward (with the Cubs) is aware of his struggles and thinks about his swing rather than just letting it come naturally. In the OF, his defensive instincts are off the charts and he just reacts.
