Tyler O'Neill hit a tiebreaking homer, Cardinals relievers combined for five scoreless innings, and St. Louis salvaged a split of its four-game series against the Los Angeles Dodgers with a 2-1 win on Thursday. The Cardinals climbed within three games of the San Diego Padres for the final NL wild-card spot, while the Dodgers fell 2 1/2 games behind the NL West-leading San Francisco Giants. "Two-and-a-half games is not very much," Dodgers shortstop Trea Turner said.
