Gailey is a Philadelphian who attended Archbishop Carroll High School and West Chester University.
The trade does not come as a complete surprise. The emergence of John Mayberry Jr. and recent signing of Laynce Nix had pushed Francisco deep onto the Phillies' bench as a fifth outfielder. And with Monday's tender deadline for arbitration-eligible players looming, it made some sense the Phillies would move Francisco rather than pay him more than the $1.175 million he made last season.
Francisco's departure could open the door for veteran outfielder Scott Podsednik, who recently signed a Minor League contract with the team.
Gailey, 26, split last season between Class A Dunedin and Double-A New Hampshire, combining to go 5-6 with a 3.41 ERA in 45 appearances. He is 23-15 with a 2.45 ERA in 175 appearances.
The Blue Jays selected Gailey in the 23rd round of the 2007 First-Year Player Draft. He is expected to provide the organization depth at the Minor League level.
Francisco, 30, came to Philadelphia as part of the Cliff Lee trade with the Cleveland Indians in July 2009. He hit .259 with 17 home runs and 75 RBIs in 225 games. Francisco's most memorable Phillies moment will be his last. He hit a game-winning, pinch-hit three-run home run in Game 3 of the 2011 National League Division Series against the St. Louis Cardinals.
