OAKLAND -- Drew Pomeranz is slated to start Game 2 of the A's double-header Wednesday, provided that he's not needed in relief in the first game. If Pomeranz is called on in the opener, A's manager Bob Melvin said rookie Arnold Leon will make his major league debut.
The A's and Mariners are playing twice Wednesday as a makeup for the April 4 game that was cancelled due to poor field conditions when a bad weather report led to the grounds crew not placing the tarp on the infield.
Melvin said he expects to have all of his relievers available Wednesday, although "some guys who threw a little more may be targeted for the night game."
Luke Gregorson threw 23 pitches in his one inning of work Tuesday night and Jim Johnson threw 25 pitches in another rough outing for the right-hander who began the year as Oakland's closer.
Johnson allowed four unearned runs Tuesday, with his own throwing error making the runs unearned. He's 0-2 with one save and an 8.44 earned run average at home, but 3-0 with a 2.00 ERA on the road.
"I think a lot of it will have to do with how he feels the first couple of times out," Melvin said.
