When I watch Castellanos hit, I look at one thing, is he spitting on the breaking ball low and away.
When he doesn't chase that pitch, he gets ahead in the count and gets something he can handle.
Pache's HR was legitimate, you can see why they're willing to give him some PA and see if they can raise his game - with his defense, .750+ OPS makes him a starter.
Marsh just keeps looking better and better, don't care what O'Hoppe does, more power to him, Phillies got themselves a good young player with lots of upside.
