OK, so Mike Trout is up now, for however brief a moment, and he looks pretty decent. Dustin Ackley has been raking since being called up. Hosmer has been decent, at times brilliant. 

Who's next? Who is the next offensive callup to produce immediately? The Diamondbacks have done nothing to stymie speculation about Paul Goldschmidt. Desmond Jennings has been on the tip of everyone's tongue all season. Leonys Martin has nothing left to prove in the minors, and Texas could use another OF, especially with the injury-prone nature of their starters. Jesus Montero is another one who has been mentioned since Opening Day, and, while he hasn't had a great season in AAA so far, could easily join the Yanks for the stretch. And Brett Lawrie was all but sitting on a plane to Toronto when he broke his hand, and figures to get the call quickly once he returns. 

So who do you see as the next important offensive callup? Who's first, who has the biggest impact, who sticks for good?
