The Rangers gave Volquez the Halladay treatment last season, busting him all the way back down to High-A Bakersfield to rebuild his mental approach and his confidence. He dominated his way back up the ladder, from the Cali League to the Texas League to the PCL. Still, I don't think anyone--probably not even the Reds--envisioned the kind of success he's experienced in MLB thus far in '08.
On the trade, I have to agree with Jacksonian. Win-win. Hamilton has been, by a mile, the best player on the Rangers team this season, earning AL player of the month for April and playing a nice defensive CF as well.
