MLB Rumor Central: Doubront over Hahn in A's rotation?

It already has been a rocky spring for Jesse Hahn, and another rough outing on Monday has left his spot in the Oakland Athletics' rotation on shaky ground, reports Susan Slusser of the San Francisco Chronicle.

Hahn, who was on the disabled list for much of the second half of last season because of a forearm strain, has an 11.15 ERA in five Cactus League starts after allowing six runs and 10 hits in 4 2/3 innings against the Indians. His last chance at claiming the fifth spot in the rotation, and possibly a roster spot, will come in a start Saturday against the Giants.

If the A’s decide Hahn needs some minor league work, that would likely open a rotation spot for Felix Doubront, who had pitched effectively before allowing seven runs last Thursday. Doubront is scheduled to pitch in a minor league game on Tuesday.

If Doubront moves up from the bullpen, that would leave a bullpen opening for rookie righthander Ryan Dull, who has a 0.54 WHIP in 9 1/3 spring innings.

One of the wild cards in the rotation is free-agent signee Henderson Alvarez, who underwent shoulder surgery in July and is expected to join the A's rotation in May.
