According to Fangraphs Reds have a 12.8% chance of winning the second spot in the Central. Reds have a better chance at a wild card, 32.4% .
This seems mostly based on strength of schedule, Reds have the toughest among NL contenders for last spots.
On WC, Reds have three home games against Brewers and can do some business there. Brewers then go into St. Louis for five games (one a Mil “home” game). Brewers’ final actual home game is today. Giants finish at San Diego.
Cards seem a tough reach as they finish with 5 at home while Reds are at Minnesota. Still, all close, you never know.
