With the MLB betting season approaching the midway mark there is still a ton left to be determined. While some fantasy players have gotten the job done, there are a handful of projected superstars that have underachieved this year. Here is a look at five players that simply haven’t delivered.

5. Derrek Lee – Baltimore Orioles

Every year the Orioles are supposed to be one step closer to contending, but every season they become lost in the fray. That outlook epitomizes Lee, who was expected to step up as one of the league’s biggest stars at this point. Lee is hitting just .242 with six home runs, and has been a major disappointment so far in 2011.

4. Joe Mauer – Minnesota Twins

The former MVP has struggled to deliver since returning from another injury this season, with a .194 average and just six RBI. Mauer has yet to hit a home run so far in 2011, and until he proves that he can deliver without dealing with the nagging injuries he has to be considered expendable.

3. Dan Uggla – Atlanta Braves

It’s hard to complain about 11 home runs, except when the star is hitting just .177 on the betting season. In addition Uggla has a ton of strikeouts, and until he can show any kind of consistency there is no way fantasy owners can rely on him.

2. Geovanny Soto – Chicago Cubs

Soto has managed to deliver in the power category so it hasn’t all been bad, but a pedestrian .227 batting average is simply not good enough for a player that was expected to lead the Cubs this season.

1.Chase Utley – Philadelphia Phillies

You have to wonder whether fantasy owners should have been able to project that Utley would continue to slide, especially since he has been trending downhill since 2007. After starting the year on the DL, Utley has managed to hit just three home runs and 16 RBI, and his .269 batting average does little to bail him out.
