an interesting article on scout.com about Joba Chamberlain. I wont bother with the link, you need to be a member to read it. But essentially, they are saying that Joba is developing his changeup throughout the season. His changeup was by far his least developed pitch coming into this season, but he has made it a point to use it. He says he throws bout 10-15 of them per game. The interesting thing is, Joba already has a plus plus fastball and a plus slider as well as a MLB average curveball. The results are good apparently, according to the pitching coaches, who seem to feel that he could develop the changeup into a league average or even plus change. What has already improved is his confidence in the pitch. He now has no qualms about using it in any count and to any location. While it still has a long way to go, that changeup could put Chamberlain in another world. Being clocked in the 97-99 range in the 6th inning of his start, Joba possesses an overpowering 4 seamer that he can locate throughout the zone and a very good slider, considered the best in the system. If the curve continues along its pace and then he throws in the changeup, he may graduate to the bigs with 4 plus pitches and plus control of all of them. This guy could be a force.
