The Phillies signed reliever Oscar Villarreal to a minor-league deal on Thursday. Villarreal, who missed the entire 2009 season recovering from Tommy John surgery, will not be invited to spring training.

Villarreal, 28, last pitched in 2008 with Houston when he appeared in 35 games, compiling a 1-3 record with a 5.02 ERA. He was 9-1 with a 3.61 ERA in 58 games for Atlanta in 2006.

The deal was first reported by Ed Price of AOL Fanhouse.

Villarreal, much like the other recent signees by the Phillies, is probably ticketed for triple-A Lehigh Valley. In the last few days, the Phillies have also signed outfielder Freddy Guzman, second baseman Luis Maza and pitchers Brian Gordon and Brian Mazone.

The Phillies also signed catcher John Purdom from the Camden Riversharks.
