It could be a crowded Spring Training in Fort Myers, Fla., this year as the Twins announced Tuesday that they have extended 25 invitations to non-roster players.That will likely put 65 players in camp when pitchers and catchers report on Feb. 18, with workouts set to begin the following day. There will be 10 non-roster pitchers, including left-hander Phil Dumatrait, who split the 2011 season between Minnesota and Triple-A Rochester. Other pitchers include Jason Bulger, Jared Burton, Sam Deduno, Casey Fien, Luis Perdomo, Daryl Thompson, P.J. Walters and Brendan Wise. The five catchers who will be in camp are prospects Chris Herrmann, Dan Rohlfing and Danny Lehmann, former Astros catcher J.R. Towles and 2011 Twins backstop Rene Rivera. The seven infielders are Aaron Bates, Sean Burroughs, Ray Chang, Brian Dozier, Pedro Florimon, Michael Hollimon and Steve Pearce. Among the three outfielders invited are Matt Carson, Brian Dinkelman and Wilkin Ramirez. The Twins also announced that familiar faces like former reliever Eddie Guardado, pitching great Jim Kaat, former manager Tom Kelly, outfield great Tony Oliva, catcher Terry Steinbach and Hall of Famers Paul Molitor and Rod Carew will be in camp as special instructors.
