The Cardinals have given themselves some separation from their National League Central rivals, holding a lead of four games over the Cubs and five over the Brewers with 15 games remaining in the regular season.
St. Louis is hosting Milwaukee in a three-game series this weekend that has major implications for all three teams in the division race. The Brewers will likely need to win the next two games to have a realistic shot at catching the Cardinals.
Chicago has some wiggle room because it is one game ahead of Milwaukee for the second wild-card spot and seven of its last 10 games are against St. Louis.
The Cardinals have a critical three-game series starting Monday against the Washington Nationals, who lead the Cubs by 2.5 games for the first NL wild-card spot.
Things haven't always gone smoothly for the Cubs in 2019. They own a .537 winning percentage, which would be their lowest since going 73-89 in 2014. Their closing schedule does leave them squarely in control of their own destiny, either as a potential wild card or NL Central champions.
