The latest addition by the suddenly splurging Pittsburgh Pirates hustled into the dugout in the sixth inning on Saturday night eager to step into the batter's box against St. Louis if necessary. Take a breath, Justin Morneau. The Pirates -- and the pennant race -- aren't going anywhere. A.J. Burnett scattered four hits over seven innings, Russell Martin hit a three-run homer and the Pirates beat the Cardinals 7-1 on Saturday night to regain sole possession of the NL Central lead.
