The Phillies were involved with three transactions on Wednesday, including the signing of two players to Minor League contracts.

Philadelphia added infielder Hector Luna and outfielder Luis Montanez, and invited both to big league camp at Spring Training as non-roster players.

The 31-year-old Luna, who spent last season with the Red Sox's Triple-A club at Pawtucket, has 311 games of Major League experience from 2004-10. He's played for the Cardinals, Indians, Blue Jays and Marlins and is a .265 career hitter.

For Pawtucket in 2011, Luna batted .283 with 14 home runs and 58 RBIs in 113 games.

Montanez, 30, spent most of last season at the Cubs' Triple-A Iowa club and batted .321 with seven homers and 69 RBIs in 92 games. He appeared in 36 big league games for Chicago and is a .223 career hitter in the Majors over parts of four seasons with the Orioles and Cubs.

Also, infielder Carlos Rivero was claimed off of waivers by the Nationals. Rivero was exposed to waivers when removed from the 40-man roster to make room for Monday's re-signing of shortstop Jimmy Rollins.
