I'm torn. I would think it would be maybe more needed stretching. But my guess is that the team makes the players stretch out extensively. It's nothing new nowadays to know that to keep a player on the field they would need a good stretching routine. I'm guessing, but I woulld think the Sox coaches monitor that.
Personally Holt looks good to me. Looks like he added some weight and some of it muscle. Gaining some fat with muscle pretty much comes with the territory. And I beleive most of these guys lose weight during the season.
You know the crazy part of this. During the first few games one announcer mentioned Benni put on 15 pounds. A human only can add at most about 2 pounds of muscle a month. Say he had 5 months of off season, gained 10 pounds of muscle, 6 pounds of fat.
