Per BetMGM on Sept. 29, the odds of the Cleveland Guardians winning the American League pennant are +1000 (10:1) and the odds of the Cincinnati Reds winning the National League pennant are +1500 (15:1). This means that the odds of both events occurring for a Reds-Guardians World Series in 2025 are +17500 (175:1).

Cincinnati came crashing into the postseason on the final day of the regular season, and the callow Reds are riding a surge of momentum they hope will carry them against the defending World Series champion Los Angeles Dodgers.

The 1975 World Series against the Cincinnati Reds was the third heart-render for the team, and one of the most brutal. Yeoman-like work by starting pitcher Luis Tiant led the Red Sox to wins in Games 1 and 4.

The Dodgers will face the Cincinnati Reds in a National League wild-card series beginning Tuesday at Dodger Stadium, needing 13 victories for the first back-to-back World Series championships in franchise history.

The Cleveland Guardians and Cincinnati Reds completed the playoff picture in grand style. They'll be among 12 teams seeking to win the World Series.
