ST. LOUIS — Adam Wainwright refused to relax against a makeshift San Francisco Giants squad.
Pitching against the Giants missing stars Buster Posey and Pablo Sandoval, Wainwright struck out 10 in his 14th complete game and third this season, and the St. Louis Cardinals completed a day-night doubleheader sweep of the San Francisco Giants with a 7-1 win Saturday night.
"You look at a lineup and you don't see some of their boppers in there," Wainwright said. "Those are key parts of their lineup. You can very easily go out there and take it for granted and give up a couple of runs because you're not ready to pitch.
"My thought today was to just respect all those guys over there and make sure I was ready to pitch," he said.
Rookie Shelby Miller was also ready. He pitched six-hit ball for seven innings and backup catcher Tony Cruz hit two doubles and drove in a pair of runs for St. Louis in an 8-0 win in the opener.
Wainwright (8-3) allowed eight hits and one run without walking a batter to close out the first doubleheader between the Giants and Cardinals in St. Louis since July 16, 1978. Wainwright threw 106 pitches and 73 strikes.
"I didn't feel like I had the best jump on my heater I've ever had," Wainwright said. "But I was locating it and my other stuff felt great. You can go a tick or two down in velocity and locate and still get the job done."
Carlos Beltran and Ty Wigginton each had two hits and drove in two runs for the Cardinals. Jon Jay, Daniel Descalso and Shayne Robinson had the other RBIs.
Dt. Louis manager Mike Matheny was happy to see his reserves contribute.
"All the way around, the guys made good plays," Matheny said. "Whenever you see your bench guys, you know they're doing the right work. So, very impressive."
The Giants had little to celebrate, as they managed just one run in 18 innings.
"It was a tough day, no getting around it," said Giants manager Bruce Bochy. "We scored one run. They played great. We didn't pitch great. We didn't hit the ball great. That's a good team over there."
Wainwright also helped with his bat when the Cardinals broke through against San Francisco's Madison Bumgarner (4-4) with three runs in the third.
Pete Kozma started the inning with a walk, and he advanced to third when Wainwright followed with a double to left-center. Kozma scored on a fielder's choice to first by Jay, and one out later, Beltran drove Wainwright and Jay home with a single to center.
Bumgarner lasted six innings and allowed five runs on six hits with one walk and six strikeouts.
In the opener, Miller (6-3) scattered six hits, stranding seven runners. His ERA dropped to 1.82. Miller struck out seven with one walk.
Matt Cain (4-3) allowed seven runs in six innings, falling to 0-3 at Busch Stadium with an 8.87 ERA in four starts.
Cain struggled in the third, when he threw 40 pitches. In the other five innings he pitched, Cain set the Cardinals down in order. He threw 101 pitches, striking out nine with no walks.
The Cardinals had seven runs on nine hits — seven singles and two doubles — in the third when St. Louis sent 12 men to the plate.
Cruz, starting at catcher instead of Yadier Molina, smacked a two-run double. Descalso hit a double and a single while Kozma had two singles in the outburst.
