The thought crossed my mind that Vargas is the one that may be traded. Skip Bush, put Vargas out there and hope he raises his value. Showcase him for a trade and when it happens, bring Bush back into the rotation (or have Gallardo out of the pen after his next start and bring Bush back then). God knows there's enough teams looking for starting pitching and a 6-1 with a 4.09 ERA isn't something those teams will laugh at. Plus, you figure the next three starts for Vargas would be the Astros, Pirates and Nationals. Three teams that you could imagine would help raise his trade value some (9th, 15th and 16th in the NL in offensive runs) before the all star break.
