"He (Walt Masterson) could be wild, Post sportswriter Shirley Povich noted in 1949. 'There is no question, though, of his stomach for the battle,' Povich said. 'Too many times he has nursed slender leads all the way to get [the Senators] home, and rarely did he miss a turn against the tough clubs, New York, Boston and Cleveland.'" - Sportswriter Joe Holley in the Washington Post (04/09/2008)
