If You're Hardcore: Red Sox to swap Buchholz, Masterson in rotation

After eight big league starts, Red Sox right-hander Justin Masterson is 4-2 with a 3.75 ERA and a 1.25 WHIP. Masterson has been filling in admirably for the injured Bartolo Colon, yet The Boston Globe reported Wednesday that Masterson will be bounced from the rotation this weekend in favor of Clay Buchholz, who was placed on the disabled list in mid-May with a finger injury. Will the move be an upgrade or a mistake for the defending champs?
