Mat Latos has been using a pitch that no one else in the Major Leagues throws.
He grips the pitch like a knuckle curve, but releases it like a changeup. It's neither his breaking ball nor his change.
"I was told in high school that it would never be a realistic pitch in the big leagues," said Latos, who has no idea where the pitch is going.
Sometimes the pitch goes straight down, sometimes it acts like a typical change and other times it veers like a curveball. Dangerously, it might also roll like a hanging breaking ball.
"The Critter," Miami Marlins bullpen coach Reid Cornelius called it. "Don't know where it's going, don't know where it's been. The Critter."
Latos uses the pitch most often in two-strike situations.
