waive Pierre, waive Pena.
Send Beckham down and let Omar/Lilli lead off and play 2nd. Consider that a temporary move: with more plate appearances, those two and Castro will come back to the mean.
EDIT: let Castro play a lot more. Let AJ sit and stew.
I'd keep Morel up for now: he should get a chance to battle back at the plate. But I'd keep looking for available 3rd basemen.
Bring up Viciedo and let him and Teahen and Lilli share time in left. Keep looking for a decent bat to bring in to play left.
The injuns' schedule has actually been very favorable: they beat up on Mariners, Royals, bad Red Sox, Orioles but were pretty average against White Sox, Angels. Now they face Red Sox, Reds, Angels and A's on the road, Tampa. If the Sox get to about 24-30 by end of May, the Indians should be closer to 30-24. If that doesn't happen, fire Greg Walker.
