Tampa Bay's best prospects are struggling.

Just among their Top 10, Matt Moore is scuffling with the big league club, Chris Archer, Alex Torres and Enny Romero are having trouble locating the strike zone, Hak-Ju Lee isn't hitting well, Tim Beckham is suspended 50 games for drugs and outfielders Drew Vettleson and Mikie Mahtook aren't off to great starts either.

One bright spot has been high Class A Charlotte shortstop Derek Dietrich. The 21-year-old had his best game of the season today, hitting a home run and two triples in a 3-for-5 game that bumped his season line up to .273/.365/.484 in 34 games.

Dietrich, the Rays' No. 13 prospect entering the season, has above-average power and ranks fifth in the Florida State League in slugging, and if he can keep the swing and miss in check, he could be an everyday infielder, though he's a likely candidate to end up moving to second or third at some point.
