Pitchers: Francis Beltran, Freddy Dolsi, Jeff Gerbe, Chris Lambert, Preston Larrison, Aquilino Lopez, Matt Mantei.
Catchers: Joe Bowen, Dusty Ryan, Dane Sardinha, Max St. Pierre, Nick Trzesniak.
Outfielders: Timo Perez, Wilkin Ramirez, Clete Thomas.
Of that group, Sardinha, St. Pierre or Trzesniak might have an outside chance to make the team as a backup catcher if Vance Wilson is not ready and Brandon Inge gets traded. In that scenario, I would expect them to try to pick up a veteran backup catcher elsewhere though. Realistically, the odds of any of the 21 invitees making the 25 man roster are not good.
Pitchers and catchers will report to spring training on February 14 and others will report on February 19.
