PHOENIX -- The A's have talked plenty in the last 36 hours about the depth of their pitching.
And while it's true that they can promote someone like Jesse Chavez to fill in as a member of the rotation to start the season, that kind of move necessarily weakens them in the bullpen.
Chavez has only made two big league starts in 191 career games. The A's have never seen him go more than 5.2 innings, and that was in relief in an 18-inning game. He was terrific in that one, throwing scoreless relief and getting the win.
Chavez, at least early on, can't be expected to go more than five innings in starts because he doesn't have the track record. If it was any other pitcher, the A's could weather that, because they'd have Chavez in the bullpen to come in the game in the fifth or sixth inning.
With Chavez in the rotation, that luxury is gone unless they can come up with Chavez Lite.
So for the final couple of weeks, the A's may stretch out Josh Lindblom and Drew Pomeranz with the idea that one of them will take Chavez's role as the man who eats innings in the bullpen.
Lindblom, acquired from Texas in the Michael Choice deal that brought outfielder Craig Gentry to Oakland, could have a chance to make the opening day roster now that wasn't there just a couple of days ago. The Rangers started him five times last year, but they seemed to have liked him in bullpen. His overall numbers weren't great (1-3, 5.46 ERA overall, but he allowed no runs in 4.1 innings in three games of relief.
Pomeranz, a lefty picked up from Colorado in the Brett Anderson trade, falls into much of that same situation. He pitched in eight games for the Rockies last year, starting four. He had an 8.10 ERA as a starter, but in five innings of relief over four games, he, too, didn't allow a run.
Until this week, both men seemed likely to be heading to Triple-A Sacramento. Now, with injuries to Jarrod Parker and A.J. Griffin opening up jobs, they have a chance to start in Sacramento.
To this point, Lindblom seems to have the edge. Both have pitched in four games, but Lindblom's 3.32 ERA is about half of Pomeranz's 6.23. But Pomeranz is scheduled to pitch in relief today in Scottsdale against the Giants, so he has a chance to bridge the gap.
