BOSTON (AP) — Pat Venditte took his warmup pitches in his major league debut with his right arm. And his left.The ambidextrous pitcher entered the game against the Boston Red Sox at the start of the seventh inning after being called up Friday by the Oakland Athletics.Wearing a specially designed glove, he threw warmup pitches with his right hand then switched to his left to face lefty Brock Holt.After Holt grounded out to first, Venditte put his glove on his left hand and pitched to righty Hanley Ramirez, who singled on the second pitch. Then, still pitching with his right arm, he got righty Mike Napoli to ground into an inning-ending double play.Fans may stare when Venditte switches his glove from one hand to the other, but the Athletics promoted him because he pitched very well this season at Triple-A Nashville.“There’s a little bit of a sideshow to it for good reason,” Melvin said.
