After his disastrous outing last night in Oakland, the Red Sox medical staff examined Justin Masterson. Essentially, they determined that he had the West Coast version of the "Fenway Flu"—suffering from "fatigue". An "extended rest" period was recommended. Masterson will miss his next scheduled start on Sunday—and this could be extended to a formal DL stint. Reportedly, he was not happy with the team's decision. Knuckle-baller Steven Wright will be the short-term replacement for Masterson.
