I agree. Body language tells a lot and you can often pick out the rookies just by how they go up and stand at the plate. Sparky used to show his nervousness and lack of confidence pretty well and you can still read it in Adams and Hill from time to time. You can see when they are concerned, defensive and clueless.

Sometimes it's just reading the player's focus and mindset and you can see when a player is 'locked in'. Shea and Bengie are most clear when are getting lazy and are just swinging to make contact without a plan of how to hit the ball well. Perhaps it's a 'contact hitter' thing. Vernon has had his spells of this too, and any run of failure, or slump, will usually show up in a hitter's expression at the plate. Rios probably felt like he was in a prolonged slump the last couple years, not doing what he believed he could do.

Nice to see that weight isn't on his shoulders now. But how's that 'superbug' infection?
