Blue Jays left-hander Ricky Romero has been frustrating hitters with an off-speed pitch this season. Hitters have asked Romero if he is throwing a splitter or a screwball, but ESPN's Buster Olney says that he throws a changeup with a classic circle grip. Romero's pitch doesn't move like a traditional changeup. "It's a tremendous finishing pitch," one general manager said this weekend. The pitch tends to move away from right-handed hitters, and reminds many of Fernando Valenzuela's screwball.
