Phillies Sign Oscar Villarreal

The Phillies signed pitcher Oscar Villarreal to a minor league deal, tweets Ed Price of AOL FanHouse.  Villarreal, 28, signed with the Royals before last season but eventually developed the need for Tommy John surgery.  He threw for teams on Friday, with the Phillies, Red Sox, Rockies, and Diamondbacks in attendance.

Villarreal's upside is limited, as he's prone to the longball and has a 1.75 career K/BB.
