Before he went to AAA, Royce looked like a hitter who was overthinking everything. His body language didn't exactly scream confidence. His AB looked very mechanical. Almost like he was going through a check list of every component of his swing before every pitch.
Lewis looks more relaxed now. His swing looks fluid. Now it seems to be...see ball, hit ball. It's only a few games, but there seems to be some loud contact. His plate discipline looks improved too.
Like I said, it's only a few games. I'm keeping my fingers crossed. If Royce has worked it out, he still has a huge upside.
