Philadelphia, PA (Sports Network) -
We're a couple of weeks into June and most of the talented minor leaguers have been called up to their "big clubs." Almost all of them have fantasy value in keeper leagues, but let's see if any of them have fantasy value for the remainder of 2010.
Buster Posey, C, San Francisco - Posey arrived in late May and has been "as advertised." Through his first 18 games, he's batting .324 with an OPS of .817. Joe Mauer has an OPS of .817. He's not Mauer, but he's already a viable fantasy option at a position of need. He's owned in under 60% of all leagues and for the price of a waiver pickup has a good chance of improving your catching situation.
Carlos Santana, C, Cleveland - Santana's arrival was a little after the main "June group" arrived. He just came up on June 11th. He's always been a good hitter throughout his minor league career. That was never the concern, and he's batted .333 over his first seven games. Santana is owned in under 45% of all leagues, meaning there is a better than 50-50 chance you could get him for a waiver pickup. He's going to start the majority of the Indians' games the rest of the year and if he's available you should pick him up.
Ike Davis, 1B, New York Mets - Davis wasn't really a mid-season call up, he arrived in late April. Because of that, we've seen enough to know the kid has power (eight homers in 196 at-bats). He's actually hit better in Citi Field than in some of the other "hitters' ballparks" (home .305, road .228). However, he's at a position where there is a lot of talent and his numbers aren't likely to be better than your starter. He could be a decent two-week substitute if your starter gets injured.
Pedro Alvarez, 3B, Pittsburgh - The heralded Pirates third baseman hasn't gotten off to a good start, going 0-for-10 in his first three games with five strikeouts. It doesn't appear as if he's ready to contribute to your fantasy squad, but sometimes even the "name" rookies struggle at the start. Continue to watch his progress, but don't put a claim in on him.
Jose Tabata, OF, Pittsburgh - Alvarez isn't the only top Pirates' prospect getting his first taste of the majors. Tabata has a nice combination of power and speed, but it's difficult to recommend picking him up and starting him until we see more.
Mike Stanton, OF, Florida - Stanton made his debut on June 8th with three hits and two runs scored against the Phillies. He's been up and down so far, as rookies often are, but hit his first career homer on Friday night. He hit 21 homers in 52 games at AA Jacksonville, but will also strike out a lot (53 in 192 AB). If you can absorb his .250 batting average, he could help you with your power numbers. He's owned in 50% of all leagues.
Stephen Strasburg, SP, Washington - If you didn't select him at your preseason draft, you had no shot at getting him when he was called up on June 8th. He's a true star in the making and his fantasy numbers already reflect that. He'll help you out in ERA (1.86), WHIP (0.78) and strikeouts (32 in 19.1 innings). Unfortunately, to get him on June 19th you'll have to give up an arm-and-a-leg in trade.
Jake Arrieta, SP, Baltimore - With Strasburg getting national attention, Arrieta's call up went unnoticed. And while he won't give you Strasburg's strikeout totals, he been very good in his first two starts, going 2-0 with an ERA of 2.77, a 1.00 WHIP and nine strikeouts in 13 innings. Almost no one has picked him up (6% owned) so if you need starting pitching help, he's your guy.
