Help with 3B injuries and prospects...

Need help with some injuries that's having me thinking I'm already in rebuilding mode this year. It's a 14 team 5x5 keeper league (price is whatever round a player's Yahoo ranking falls on each round [i.e. 1-14 Y! rank = 1st round price, 15-28 = 2nd round price, etc.]. There was a huge run on 3B in the redraft and I was left with Freese as my starting 3B and Izturis filling in now. With him being out for at least a month and a half, I need help with picking up someone who might be called up when June rolls around. I have Dustin Ackley and Mike Moustakas riding the bench until they're called up. Lonnie Chisenhall, Eric Hosmer, and Mike Trout are all available in FA and I have an open roster spot. Which one of the three would you pick up expecting a call up here in the next couple of weeks? With Ackley slumping like he is, should I consider dumping him for another potential June callup? Here's my roster: c - Posey c - McCann 1B - Lind 2B - Beckham 3B - Izturis SS - Andrus CI - Wallace MI - A. Escobar OF - Quentin OF - Kemp OF - Fowler OF - David Murphy OF - Sands Util - Span BN - Ackley BN - Moustakas DL - K. Morales DL - Freese Thanks!
