Ken Rosenthal passes this note along in his column a few days back:
Tampa Bay Rays scout Rob Ducey, a former major league outfielder, has organized a Professional Free Agent Showcase for Feb. 2-4 at Al Lang Field in St. Petersburg, Fla.
[...]
Free agents must have experience in the U.S. or international pro leagues in order to take part. That should make for a more select talent pool than normal tryout camps. And the timing allows plenty of time for teams to agree to terms with players and invite them to their spring camps.
Odds are the Rays hold some interest, if for no other reason than to have one of their own organizing the event in their backyard. How much is probably dependant on what players actually show up to this thing.
