The Rays added four players to their 40-man roster, including a pair of their top infield prospects.

Former top-overall pick Tim Beckham, shortstop Hak-Ju Lee, and pitchers Enny Romero and Felipe Rivero have all been added to the team's 40-man roster.

Beckham, taken first overall in 2008, spent 2012 in Durham, hitting .256 with six home runs and 28 RBI in 72 games.  The 22-year-old was named the team's eighth best prospect by Baseball America.

Lee, 22, hit .261 with four homers, 37 RBI and 37 stolen bases.  The shortsop, acquired prior to the 2011 season in the trade involving Matt Garza, was named the top position player prospect and third-best prospect overall by Baseball America.

Rivero spent 2012 in low-A Bowling Green, going 8-8 with a 3.41 earned run average in 27 appearances (21 starts).  The 21-year-old also represented the World team at this past year's XM Futures Game.

Romero, 21, also represented the World in the XM Futures Game.  He went 5-7 with a 3.93 earned run average in 25 appearances (23 starts) with high-A Charlotte.
