With Jameson Taillon mowing down hitters in Triple-A while starting in tandem with Jeff Locke, June fast approaching, and an obvious date on the calendar for the Pirates to bring a minor league pitcher up (their makeup game against the Rockies has been scheduled in Denver on June 9th between home games against the Mets on the 8th and the Cardinals on the 10th), Jeff Locke is officially on the clock for the millionth time in his Pirate career. I think you can make a pretty easy argument to keep him in the rotation and move Juan Nicasio to the bullpen, but that can go either way at this point.
