The Marlins have reported their list of non-roster invitees to Spring Training.  In other words, the guys who aren't the 40-man roster who get tryout in the big league camp.  Fortunately, they did this via a press release, so I get to steal the whole thing.  Here it is:

The Florida Marlins today announced that they have extended Spring Training invitations to 22 non-roster players. The announcement was made by Marlins President of Baseball Operations Larry Beinfest.

The Marlins have signed the following 13 players to minor league free agent contracts with invitations to Spring Training: Right-handed pitchers Clay Hensley, Seth McClung, Kasey Olenberger, Matt Peterson, Chris Schroder, Scott Strickland, Derrick Turnbow and Jose Veras; catcher Vinny Rottino; infielders Brian Barden, Hector Luna, Donnie Murphy and Danny Richar.

The following nine organizational players were extended Spring Training invitations: Left-handed pitchers Dan Jennings and Jay Voss; catchers Brad Davis and Chris Hatcher; infielders Matt Dominguez, Ozzie Martinez and Logan Morrison; outfielders Bryan Petersen and Michael Stanton.

For the eighth consecutive season, the Marlins' Spring Training headquarters will be based at Roger Dean Stadium in Jupiter, Fla. Pitchers and catchers will hold their first workout on Feb. 20, and the first full-squad workout will be Feb. 24.

As of today's announcement, the Marlins will have 61 players in Major League Spring Training camp.

Normally the ones to watch are the minor league free agent who have invitations to Spring Training since they have the better chance of making the club.  The organizational players are, typically, there to see how they are fairing against major league talent.  The one exception to that rule, but not always, are the catchers.  A whole bunch of catchers are needed to make sure that all of the pitchers are able to get their work in.
