I think Davey may be teaching Rendon a lesson after assuming the catch was going to be made and slowing down only to get thrown out at home on Sunday. That is the only thing I can think of - he has rubbed Davey the wrong way.
that, and he's trying to get lefties into the line up against Hudson. His OPS against lefties over his career is almost 100 points higher than against righties. It does not hold for our regulars, as Werth and Desi have the highest OPS against him. Espinosa is the next highest and the highest among guys who hit lefty against him.
I'm guessing he does not want Rendon and Moore having their first PAs against Hudson on the same night.
