From ESPN's Buster Olney:

Imagine DeRosa as a big hunk of tuna, bait on a hook. One of the looming shadows circling below is that of the New York Yankees, who are weighing options and haven't decided whether to take a shot at the versatile veteran.

DeRosa, 34, is hitting .266 with a .333 OBA and .446 SLG so far this season. His career line is .278/.347/.423. He's a versatile defender, who has spent substantial amounts of time at short, second, third and right field and has seen time in left field and at first, as well.

Joseph Pawlikowski at River Ave. Blues analyzes DeRosa's potential and is right when he says that it's all about what the Yankees would have to give up. DeRosa could be a nice addition, certainly, but if it costs a prospect of note to acquire what may very well amount to a rental (DeRosa becomes a free agent after this season), it's going to be difficult to pull the trigger.
