That particular outcome -- a .220 average after three months of a rookie season -- is the chance we take with any youngster in fantasy baseball. For all the talent a player might have, it could take awhile for it to show up as the player adjusts to the big stage. Of course, that doesn't help your team win a fantasy title.Still, every fantasy -- and major league -- team is looking for a boost, and as the calendar turns to June, the concerns over "service time" or "super-two" status or "starting a player's (major league service) clock" are lessened, and we start seeing more prospects make their ascent. Today we'll look at a few of the bigger names, and what you should expect from them.For the purpose of this blog, I don't address players who have already seen major league time this season, such as Brandon Belt, who is getting called up again following the Buster Posey injury, and Julio Teheran, one of the top starting pitching prospects in baseball (though he's not quite ready to stick in the bigs just yet). I also don't address players who have recently been called up, such as Eric Hosmer, Domonic Brown, Andrew Oliver and Rubby De La Rosa, who has emerged in Los Angeles and could move to the back of the Dodgers' bullpen soon.This list is not an exhaustive one, just some quick capsules that focus on some of the key players:
