Right-hander Jack Flaherty returns to the scene of his major league debut last September when he closes out a four-game series for the St. Louis Cardinals against the San Francisco Giants on Sunday afternoon. Flaherty (3-4, 3.19 ERA) will attempt not only to give the Cardinals a 3-1 win in the four-game series but to reward manager Mike Matheny with his fifth series win in seven return visits to San Francisco, where he played the final two years of his career. Matheny has never lost a series as a manager in San Francisco, winning four and tying the other two.
