Is this true? What did we give up?

This did happen. It appears to be a move made for organizational depth, with the chance he could return to the bigs at some point. The two sides haven't worked out what the Pirates will get in return. "STBNL", I guess, with the S(omething) probably being cash.

I hear we gave them Liriano:p
