Ethier is a weird dude. When he plays like this, he's so good at coming back from a 2 strike count, and waiting for a pitch he can drive. For some reason, he can't stay at this level. He always slumps after these spurts. He has the potential to play like this most of the time. That's why you see Joe pointing his finger at him at the end of the clip. He's trying to get him to stop having those slumps n' spurts.
