Murcielago I dont know if I can narrow down the nastiest stuff to one guy, but I'l tell you who has the nastiest pitches in the system. First off Munoz' curveball is down right ridiculous, Sander's cutter/slider is the best I've seen from a lefty, Honel's knuckle curve is unhittable at times, Almonte and Heath Phillips both have awesome changeups, and Malone's fastball is hard with some serious movement. But if I had to pick one guy who I wouldnt want to face it would be Sanders b/c he throws 88-92, his slider breaks righties bats and his changeup keeps the hitters honest. He is a quality lefty reliever that should get a shot at the Sox soon. If Valentine were still with us I'd rate him the nastiest righty in our system but he's with Oakland now so the next best righty in my mind is Honel.
