I like Kath better. Montgomery is very raw. He has a great frame and is very athletic. The tools are obvious but he lacks feel to hit and instincts for the game. Usually those guys go to school because it's very hard to learn feel to hit facing 92+ everyday. Kath is more polished, has a better swing and a much better chance to get to his power which is substantial. I really like they picked them both because the risk of Montgomery is mitigated by Kath.
