The Cincinnati Reds hit St. Louis Cardinals starter Carlos Martinez for two runs in the first inning and never looked back, winning 9-1 Friday night at Busch Stadium.
Martinez (6-5) gave up three of those runs in five innings of work, allowing six hits, walking two, and giving up a third inning home run to Scooter Gennett.
It's the sixth game this season where the right hander has thrown five innings or less.
Jesse Winker's two run double in the opening inning gave Cincinnati a 2-0 advantage before the Cards put a run on the board in the bottom of the first on Yadier Molina's RBI single.
Gennett's long ball, his 16th of the season, gave the Reds a 3-1 lead.
Cincinnati batted around in the seventh inning, putting five runs on the board, with the big blow coming on rookie Dilson Herrera's first career pinch hit home run off Cards reliever Sam Tuivailala.
That made it 8-1, with the Reds adding another run in the eighth.
The loss drops St. Louis to 47-45 overall and 23-23 at home.
The Cardinals will try to get it turned around on Saturday when they send Jack Flaherty (3-4, 3.34 ERA) to the mound against Cincinnati's Luis Castillo (5-8, 5.53 ERA).
First pitch is set for 3:10 p.m.
