St. Louis topped Houston 4-1 on Tuesday to increase its lead over the Los Angeles Dodgers to 1.5 games. They'll send Lance Lynn to the mound Wednesday night against Houston's Lucas Harrell in hopes of winning their third straight game. The Cardinals (78-70) had lost 13 of their previous 19 games before handing Houston its majors-worst 100th loss Tuesday night.
The Dodgers will look to keep pace on the road against the NL-best Washington Nationals, where they play a doubleheader after getting rained out Tuesday night.
St. Louis is well behind the Atlanta Braves for the top Wild Card spot, which will get the privilege of hosting the one-game Wild Card playoff before the start of the divisional round. After L.A. in 2nd place, the surging Milwaukee Brewers are 2.5 games back while Pittsburgh is 3.5 back and Philadelphia is 4 back.
