Ahhh, I like both, and own both. Clippard is almost a year older though has pitched better this year at AA. Gallagher seems to have lost his control since being called up to AA, I'm sure he can get that all figured out as he does have some decent control but the way they are going right now, you would have to lean toward Clippard. Neither have a big fastball but they both rely on there secondary pitches. Clippard more his change and Gallagher more his curve. They seem to have good command of all there pitches which is nice and a must since like I said they don't have overpower stuff.
I like them both equally, but if I had to choose it would probably be Clippard because he is showing me a little more in AA this year than Gallagher.
