Heat mapping Mariano’s cutterBy
“The pitch didn’t get there enough,” said Mariano Rivera after giving up what proved to be the game-winning homerun to Bobby Abreu on Monday. “It was middle in, not in enough. He put good wood on the ball. You have to make sure you get it there. It didn’t get there.” Two poor outings in a row for the greatest closer of all-time always creates an uproar, so Bill Chuck broke out some heat maps.
They show that Rivera’s cutter has been slowly drifting more out over the plate against lefties, but I’m not sure I agree with Bill’s conclusion that it’s a result of the pitch not cutting as much as it once did. The PitchFX data shows that it’s still getting as much horizontal break as the last two years, if not more. Perhaps it’s just a location issue, maybe he’s having a harder time getting the pitch in on the hands of lefties? If so, is that something that could be fixed by moving a little closer to the first base side of the rubber? I have no idea, just kinda spit balling here. Either way, check out Bill’s post, very interesting stuff.
