For those of you who were not able to see Gustavo Chacin pitch last time out, you're in for a treat. Provided, of course, that he looks like the same pitcher I saw making his major league debut last week.
There are two distinct features in Chacin's delivery:
1) He has a hitch near the beginning of the windup which some observers think is a balk. By the rules, it is indeed, since he comes to a stop and restarts his motion. But since this is his normal full wind-up (and is not used with runners on base) the umpires will probably let it go.
2) He throws out his glove hand where the ball will come flying out from before his pitching arm comes forward; this probably distracts the hitter just a little bit. It looks a little like a windmill.
