Hours after winning the National League’s pitcher of the month award for August, Flaherty started September with a career-best eight shutout innings Tuesday in the Cardinals’ 1-0 victory against San Francisco at Busch Stadium. Flaherty took a no-hitter into the sixth inning, didn’t allow a Giants runner to reach second base, and muscled the first-place Cardinals to their 20th win in their past 25 games. His ERA dropped to 0.59 in his past seven starts. The only other Cardinals with similar seven-start runs in the past 50 years, Chris Carpenter and Bob Gibson, have won Cy Young awards and wear red blazers to team functions.
