NEW YORK – Long after Mark Mulder and Pedro Martinez were gone, Larry Walker helped the St. Louis Cardinals rally past the New York Mets.

Walker pinch-hit in the eighth inning and had a go-ahead sacrifice fly against Roberto Hernandez, leading the Cardinals to a 7-6 victory Saturday.

Mulder allowed six runs and 10 hits in five-plus innings, his ERA rising from 2.70 to 3.44. Martinez gave up five runs -four earned – and five hits in six innings.

Martinez breezed before walking John Mabry and giving up a long two-run homer to Mark Grudzielanek.

Grudzielanek made it 3-0 in the fourth with an RBI single after Mabry’s double off the wall in right-center.

Abraham Nunez homered leading off the sixth, and Grudzielanek hit a sacrifice fly after first baseman Miguel Cairo let a grounder carom off his glove into foul territory for an error, putting runners on the corners with one out.
