A.J. Burnett scattered four hits over seven innings, Russell Martin hit a three-run homer and the Pittsburgh Pirates beat the St. Louis Cardinals 7-1 on Saturday night to regain sole possession of the NL Central lead.
Neil Walker added three hits for the Pirates, who improved to 79-56 and moved within three victories of their first winning season since 1992.
Burnett (7-9) gave up one run while striking out six and walking one.
He received plenty of offensive help only hours after Pittsburgh acquired first baseman Justin Morneau from the Minnesota Twins.
Morneau arrived in the Pirates' dugout in the sixth inning.
By then Pittsburgh had things well in hand.
Martin keyed a five-run second with his drive off Lance Lynn (13-9).
