The St. Louis Cardinals are revving up for a strong postseason push as they continue their four-game series against the visiting San Diego Padres on Saturday. St. Louis has won three straight contests, including the first two of its set versus San Diego, to grab hold of the first wild-card spot in the National League and climb within two games of first-place Milwaukee in the Central Division. Matt Adams and Jhonny Peralta each recorded two hits and an RBI on Friday as the Cardinals rode a strong performance from starter Lance Lynn to a 4-2 victory.Yasmani Grandal belted a pinch-hit solo homer in the ninth inning and the Padres brought the potential tying run to the plate before suffering their second straight loss following a five-game winning streak. Early control problems Friday were the undoing of ace Tyson Ross, who began the contest by walking the bases loaded and wound up allowing two runs in the first inning en route to having his four-game winning streak snapped. San Diego needs to turn things around quickly as it sits 6 1/2 games behind Pittsburgh for the second wild-card spot, with five teams between itself and the Pirates.TV: 7:15 p.m. ET, Fox Sports 1PITCHING MATCHUP: Padres RH Jesse Hahn (7-3, 2.52 ERA) vs. Cardinals RH Shelby Miller (8-9, 4.17)Hahn did not figure in the decision against Colorado on Monday after yielding three runs on five hits and three walks in five innings.
