The Bucs might send Hayden Penn to Japan:

Chiba Lotte is closing in on an agreement to bring in Hayden Penn, who is currently playing for the Pirates’ 3A affiliate. Rotation depth is Lotte’s weakness, particularly with Yuki Karakawa on the shelf, and the Marines have a foreign roster spot to allocate, so another starter is a sensible acquisition.

If this goes through, what do you suppose the Pirates can hope for in return? Money? Not having to worry what to do with Penn?

UPDATE by Charlie: Yes, definitely cash.
