LOS ANGELES (AP) — Jon Jay hit a go-ahead RBI double during a three-run 12th inning and the St. Louis Cardinals split of a four-game series against the Los Angeles Dodgers, beating them 5-2 on Sunday and regaining undisputed possession of the second NL wild card spot. John Ely (0-2) issued a leadoff walk to Matt Carpenter and Jay drove him on from second base with a line drive into the right field corner on an 0-2 pitch. Jay scored on an infield hit up the middle by Allen Craig and Yadier Molina walked with the bases loaded. Rookie Shelby Miller (1-0) pitched one inning for his first major league victory.
