From the Article:
His name is Pat Venditte, he's 23, and he's pro baseball's only ambidextrous pitcher. This living piece of history is more than a YouTube star; he's throwing almost daily for the Charleston RiverDogs, the Yankees' Single-A club. And he's not just throwing: He's blowing through hitters like a Cub Scout through Skittles. At one point in April, the closer's ERA was 0.00 in 6 1/3 innings, and he hadn't blown a save in five games.
Last season, he had 23 saves for the Staten Island Yankees, with a 0.83 ERA. And best of all, the kid can relieve himself!
He wears a specially made six-fingered Mizuno glove with two thumbs. (His Dominican teammates call him Pulpo, Spanish for "octopus.") When he warms up, he throws four pitches righty and four lefty. You should see the opposition when he does it. It's as if they had seen a ghost. Wait—did you just see that? If a righty is up, he throws righty, and vice versa. Whenever Venditte switches sides, everybody in the Charleston ballpark is encouraged to switch seats.
