Who's the next big time prospect to be called up?

[Carew7]

now that scherzer and bruce and kershaw are up... i finally have the #1 waiver and was wondering what peoples opinions were for who's worthy of it... i know guys like david price from the Rays but thats a lonng time from now if he even comes up this summer... whats your opinion?

chase headley of the padres has a good chance of getting called up in June once his free agency clock ticks onto another year... he could put up numbers similar to longorias.... also with price's delayed start in the minors due to injury and being overworked at vanderbilt its very unlikely that he will hold any value in non-keeper fantasy leagues this year...especially with the emergence of edwin jackson as a solid contributor thus far. On a side note if chris perez of the cardinals is still available, dont waste waiver position on him but pick him up, he is the closer of the future in st louis and has looked unhittable in what small sample he has shown in the week and a half he has been called up..
