Nolan Gorman sparked St. Louis’ three-run ninth inning with a tie breaking solo homer off Pierce Johnson, and the Cardinals topped the Colorado Rockies 9-6 on Tuesday night.

Gorman’s third homer of the season gave St. Louis a 7-6 lead. Paul Goldschmidt then singled in Brendan Donovan and scored on Tyler O’Neill’s single.

Tommy Edman and Juan Yepez also went deep for the Cardinals, who trailed 6-2 after six innings. Nolan Arenado hit a three-run double in the seventh, and rookie Jordan Walker extended his hitting streak to 11 games.

Giovanny Gallegos (1-0) pitched 1 1/3 innings for the win, and Ryan Helsley gave up a pair of singles before retiring three straight for his second save.

The Cardinals scored four unearned runs in the seventh after McMahon booted Edman’s two-out grounder to second, loading the bases.

The Rockies had opened a 6-2 lead with five runs in the fifth, batting around against Miles Mikolas. McMahon hit a three-run drive and Cron followed with another homer. Yonathan Daza added a sacrifice fly.

Edman homered in the first, snapping a 13-inning scoreless streak to start the season by Colorado starter Kyle Freeland, and Yepez went deep leading off the third.
