Harrison Bader put St. Louis ahead with a checked-swing single off the glove of Giants first basemen LaMonte Wade Jr. in the seventh inning, and the Cardinals went on to a 2-1 victory over San Francisco on Sunday.
The Cardinals won the season series, taking two out of three against the Giants in both series them.
Matt Carpenter hooked a ground-rule double down the right-field line off former teammate John Brebbia (0-1) in the seventh. Jose Rondon was brought in to pinch-run, and he advanced to third on a flyout by Paul DeJong. With the infield in, Bader hit a grounder that deflected off Wade's glove, scoring Rondon.
Bader is now 6 for 14 over his last five games.
Alex Reyes got the final three outs for St. Louis, setting a major league record by converting his 24th straight save chance to start his career. LaTroy Hawkins held the previous record of 23.
Paul Goldschmidt singled to left in the fourth inning to extend his hitting streak to 13 games. It's the longest streak by any Cardinal this season.
Jake Woodford (1-1, 4.62) will start against RHP Alec Mills (4-2, 4.84) and the Chicago Cubs for the start of a four-game series Monday night in St. Louis. After three relief appearances versus Chicago, Woodford will be making his first career start against the Cubs.
