They need a backup catcher and they already saw enough of Zavala. If Castillo wasn't injured he'd be starting more. Palka or Collins will go down when Beef returns.
Cease absolutely has a better arsenal than Kopech. Giolito does too. Kopech has the biggest fastball. It is going to be interesting to see which one turns out the best.
Arguable. Giolito's slider has been among the best, if not the best in baseball this year among starters so idk. Kopech hasn't pitched this year so we shall see.
Kopech throws a nice tight 12-6 hook. Not a ton of movement like the other two but late break. The huge issue that I've seen and it could be an issue is that they all throw some variant of fastball- curve - slider- change
Oh absolutely. Giolito's problem with his curve is being able to throw it for strikes. It has nasty movement but he can't spot it. Giolito has a much better slider though.
