Conor Jackson, 1B (ARI): Conor Jackson has been on and off rosters throughout this season and now it's time to add him again. In fairness, in most deeper leagues he's been owned all the way through.

He hit .348 with five home runs, 24 RBIs and 24 runs in April. He cooled off in May, hitting only .247 with one home run and 10 RBIs, but he's cooking again in June. He's hitting .324 with one home run, five RBIs and six runs in 37 at-bats. That's not as out-of-this-world as his May numbers, but it's better than waiver-wire production. His hitting has coincided with the Diamondbacks' play. They are struggling right now but as they come around, he should continue to be more than serviceable.


Chase Headley, OF (SD): Chase Headley is one of the San Diego Padres' top prospects and he has been called up to give their feeble offense a boost. I'm surprised it didn't happen earlier since Headley has been beating up minor-league pitching. He hit .305 with 13 home runs in 259 at-bats and is a career .301 hitter in the minors. Considering who the Padres have pawned off as "hitters" so far this season, his call-up should have come sooner.

He collected a pair of hits in his debut against Andy Pettitte and the New York Yankees. The upside looks decent with Headley but as an outfielder, there are probably better options in your league for now. Keep an eye on him.

Jeff Clement, C (SEA): The Seattle Mariners have mishandled top prospect Jeff Clement - like they've mishandled a lot of their prospects - but he might be ready to get his turn in the big leagues. First of all, general manager Bill Bavasi was fired and one of the interim manager's priorities was to get Clement back up with the Mariners. The Mariners reportedly plan to release Richie Sexson (according to The Daily Herald of suburban Seattle), which will shift around the infield. If plans go accordingly, this could land Clement a daily catching role.

Clement struggled when he was first called up and then was sent back down just as he started to get acclimated to the majors. He's proven all he needs to prove in the minors and could be a very effective hitter right off the bat.

Mike Aviles, SS (KC): Sticking with the emerging prospect theme, how about Kansas City Royals 27-year-old rookie, Mike Aviles? His stellar production was definitely not expected.

Aviles was tearing up the Pacific Coast League when he got the call-up. He's continued his hotness for the Royals but to be honest, I didn't take notice until he hit the game-winning home run against the St. Louis Cardinals on Tuesday night.

In 42 at-bats in June, Aviles is hitting .368 with three home runs, six RBIs, 12 runs and a stolen base. He looks like the ideal use-and-lose candidate.

Fred Lewis, OF (SF): Fred Lewis is back on my fantasy radar this season. While Curtis Granderson has been AWOL, Lewis has produced numbers that we expected from Granderson. Lewis slumped in May, which earned him the boot off of many fantasy rosters, but in June, he's back to bringing it. He's hitting .345 with two home runs, 10 RBIs, 12 runs and two stolen bases in 55 at-bats. Here's what he projects to finish with this season: .285 AVG, 101 runs, 13 home runs, 49 RBIs and 27 stolen bases. Take that Curtis Granderson.

Hank Blalock, 3B (TEX): This is just a quick update on the injured Texas Ranger. Hank Blalock tore his left hamstring and was placed on the 15-day DL on April 26 and is just about to start. Assuming everything goes fine, he should be back with the Rangers next Tuesday.
