According to Matt Eddy of Baseball America, the Marlins have signed OF DeWayne Wise, infielders Joe Thurston and Jamie D'Antona, and catcher Clint Sammons to Minor League contracts. 

Clark Spencer had this to say about Wise:

Wise is the most intriguing member of the group, and could serve as either outfield insurance and/or a lefty bat off the bench. He plays all three outfield positions and has hit .308 as a pinch-hitter over his career. is a lefty bat who will give a little depth to the outfield, having played all three positions.

All four have Big League experience, and will get a look-see in Spring Training.

Yes, I just said look-see. Craig is rubbing off on me.
