St. Louis, the defending World Series champion, beat Cincinnati 4-2 to clinch at least a tie for the second wild card. One loss by the Dodgers to San Francisco or another Cardinals win would lock up a playoff berth for St. Louis.
Division champion Cincinnati is tied with Washington for the best record in the National League. The Reds must finish with a better mark than the Nationals to earn home-field advantage throughout the postseason because Washington won the season series.
San Francisco already has already clinched the division title and will open the playoffs at home Saturday against Cincinnati or Washington. Los Angeles beat the Giants 3-2 Monday night to stay alive in the wild-card race. The Dodgers are two games behind St. Louis with two to play.
