Baseball HQ, Ron Shandler was asked to name an American League hitter and pitcher and National Leagues ones who he believes offer good upsides in the second half.  Here are the four players named (around 32:50 of the podcast).

American League:
Hitter:  3B Melvin Mora Baltimore Orioles
Pitcher: SP A.J. Burnett Toronto Blue Jays

National League:
Hitter:  SS Jimmy Rollins Philadelphia Phillies
Pitcher:  SP Roy Oswalt Houston Astros

Mora should be readily available in most mixed league formats.  Rollins likely can't be acquired for anything less than his 1st round value.  The two pitchers should be available at a discount to their draft days values due to lack of effectiveness of both and injury issues for Oswalt.
