ST. LOUIS (AP) — Rookie Shelby Miller won his 15th game, and Yadier Molina had the go-ahead hit for the St. Louis Cardinals, who wrapped up a three-game sweep of the Washington Nationals and moved another step closer to the NL Central title with a 4-1 victory on Wednesday.

Jordan Zimmermann missed his only shot at 20 wins, allowing four runs in seven innings. The Nationals had five hits one day after breaking up rookie Michael Wacha’s bid for a no-hitter in the ninth inning.

Matt Adams hit his eighth home run since replacing injured Allen Craig and doubled for the Cardinals, who led the Pirates by 2½ games with three games to go. The Reds lost 1-0 to the Mets on Wednesday and were eliminated from the divisional race.
