Webb
An MRI exam of Arizona right-hander Brandon Webb's shoulder showed his the source of his discomfort is muscular, not structural, opening the possibility that the Diamondbacks' ace could make his next scheduled start, Friday at San Francisco.
"It's down in the meaty part of the back of the arm," Webb said, according to the Arizona Republic. "When we get in there and do some therapy on it, it seems to loosen up and free me up, so that's encouraging."
Webb, whose 22 wins led the National League last season, experienced stiffness in his shoulder Monday in the fourth inning of Arizona's 9-8 Opening Day victory against the Rockies, in which he allowed six runs in four innings.
Yusmeiro Petit is taking Webb's spot in the rotation Saturday night against the Los Angeles Dodgers.
