ST. LOUIS (AP) Yadier Molina's 100th career home run in the bottom of the eighth inning snapped a tie and the St. Louis Cardinals beat the San Francisco Giants 4-3 on Wednesday night.
Molina added an RBI single in the first and rookie Stephen Piscotty homered in the third for St. Louis, which took two of three from the NL West-contending Giants. The Cardinals are 77-43 overall and 46-19 at home, both tops in the majors.
Kevin Siegrist (5-0) allowed a walk in the eighth and Trevor Rosenthal earned his 38th save in 40 chances, striking out pinch-hitting pitcher Madison Bumgarner to end it. Siegrist won both of the games in the series and the Cardinals wrapped up a 6-3 homestand with three 2-1 series wins and have won six consecutive series overall.
Molina led off the eighth by lining an 0-1 breaking ball from Hunter Strickland (2-3) into the left field stands for his fourth homer of the year.
Brandon Crawford and Kelby Tomlinson had two hits and an RBI apiece for the Giants, who missed a chance to pull one game behind the Dodgers.
Piscotty's second career homer put the Cardinals ahead 2-0 in the third, two innings after center fielder Juan Perez scaled the wall to rob him of a long ball in one of the top defensive plays of the season at Busch Stadium.
The Giants' Matt Cain ended a run of four poor starts, allowing two runs in six innings, and contributed a bases-loaded sacrifice fly. The Cardinals' Jaime Garcia gave up three runs in 6 1-3 innings.
The Cardinals manufactured the tying run in the seventh on two hits, one of them an unintentional swinging bunt by Brandon Moss, and a fielder's choice RBI. Rookie Tommy Pham's headfirst slide dislodged the ball from catcher Andrew Susac on Matt Carpenter's grounder to second.
