He literally made the move to go lefty on left and had no other thought. He didn't even think the other team would do the obvious and pinch hit. It was pretty much guaranteed the Cardinals would pinch hit and Buroki would face a right handed lol.
He also seems to give Berrios more respect than other players on the team who have handled situations well, like Phelps and Manoah. This guy just has zero feel for the game, or even his own players.
