As Jane Lee writes, the A's now have two holes in their rotation, in a sense, as they're down Scott Kazmir and the previously but still recently injured Jesse Hahn. It looks like the obvious choices to fill those slots, Drew Pomeranz and Chris Bassitt, will in fact fill those slots.

I would guess that the next injury (or trade of Jesse Chavez?) will give us Sean Nolin in the rotation, but there's still Cody Martin as well, and the more trades that happen, the more likely there are to be holes on the 40-man roster that could be filled with Triple-A starters. Dare we even say Barry Zito's name? (There's also Brad Mills.)

I'd say Arnold Leon, too, except that he hasn't made a start since May 15th in the PCL. He's pitched out of the bullpen in the majors, of course, but even after he was sent down to Nashville in June, he's spent the last month pitching as a reliever even there, and doing it reasonably well: in 13 innings in relief since June 21st, he's struck out 10 and walked not a batter while allowing a .520 OPS.
