Sean Newcomb had an occasional rough outing before his near no-hitter, but now they have become nearly the norm for the Atlanta Braves left-hander. Since falling one strike short of a no-no against the Los Angeles Dodgers on July 29, Newcomb has allowed 18 runs in 13 1/3 innings during three starts at SunTrust Park. Newcomb will try to get back on track Tuesday night, but it won't be easy against the Boston Red Sox, who have the best record in the majors.
