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 (19-9) 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 2 1/2 games with three games to go. The Reds lost 1-0 to the Mets on Wednesday and were eliminated from the divisional race.
