Believe I'd love to see Stro do that as well, but mostly because Stro works the lower corners so it would jump on batters. High and low is a great idea but Hutch generally works right in the middle of the zone at belt level, instead of the top or bottom of the zone. That's the issue with Hutch, the location is bad a lot of the time.
EDIT: LOL Carrera holy s***!
I haven't seen anything from Hutch there that makes me all that encouraged. If he wants to work up, that's fine, same if he works down, just don't work middle of the strike-zone, that's just asking for it.
