   Edgar Gonzalez allowed two hits and one run in five innings against the Reds, who came in with a magic number of 14 for eliminating second-place St. Louis. Gonzalez (2-0) walked one and struck out six. Relievers Wesley Wright, Mickey Storey and Wilton Lopez combined for eight strikeouts over four shutout innings.
