A’s Mazzaro to make major league debut Tuesday

CHICAGO — Oakland Athletics right-hander Vin Mazzaro will make his major league debut Tuesday night.

The A’s said Monday they will call up Mazzaro to start the second game of their series against the Chicago White Sox. The 22-year-old Mazzaro, a third-round pick in the 2005 draft, was 2-2 with a 2.38 ERA for Triple-A Sacramento.

Mazzaro will join fellow rookies Trevor Cahill, Brett Anderson and Joshua Outman in the rotation.

“He’s pitched about as good as you can pitch at that level so this is the next step, obviously,” manager Bob Geren said.

Oakland has the worst record in the American League, but Geren said that did not factor in the decision to bring up Mazzaro.

“Honestly, he gives us the best chance to win,” he said. “He is the best guy to put into that slot.”

Edgar Gonzalez, originally scheduled to start Tuesday, will work out of the bullpen.
