AL Pennant Odds

Odds as of July 19, 2021.

• July 19: The gap between the legitimate playoff contenders and the rest of the field has been set between Toronto (+1100 pennant odds) and Cleveland (+2500 pennant odds).
• July 5: The Red Sox (+492) are finally getting the respect they deserve. They sit third behind the Astros (+245) and White Sox (+320).
• June 27: The Astros  (+278) have taken over as AL favorites from the White Sox (+358). The Yankees (+508) are a nonsensical third, sitting 5.5 games out of a playoff spot.
• June 21: The Yankees are as long as +800 (fifth-favorite), sitting 4.5 games back of the division leading Red Sox and battling tooth-and-nail for a Wild Card spot.
• June 14: The White Sox are now the clear favorites. They have the best run differential in the AL (+106) and the biggest division lead (5.5 games). No other team is all the certain it will be in the postseason field.
• May 25: The Red Sox (+867) have improved the most since Opening Day, while the Twins (+2267) have fallen the furthest.
• Apr. 6:  A 5-0 start has the Astros back among the top-five favorites in the AL, improving from +1033 to +850 after just a week of action.
• Feb. 10: NYY continues to sit atop the odds, but the White Sox have improved considerably during the offseason.
• Oct. 28, 2020: The NY Yankees have opened as +275 AL Pennant favorites.

Past 10 American League Pennant Winners

No team has achieved more postseason success than the Yankees, who have won 40 American League pennants since 1921. New York captured its most recent pennant in 2009, defeating the LA Angeles in six games in the American League Championship Series.

NL Pennant Odds

Odds as of July 5, 2021. 

• July 19: The five-team playoff field is coming into focus in the NL and the pennant odds reflect that: fifth-favorite Milwaukee is at +525 while sixth-favorite Atlanta is a distant +1867.
• July 5: There is a steep drop after the top five (LAD +175; SD +342; NYM +450; MIL +517; SF +733). The rest of the NL is at least 5.5 games out of a playoff spot. Fifth-favorite ATL has long +1767 pennant odds.
• June 27: The Brewers (+783) have improved the most recently, odds-wise, thanks to a surge that’s put them three games up on the rest of the NL Central.
• June 21: The Giants are now the fourth-favorite, surpassing the Braves and Cardinals.
• June 14: The Mets (+433) have solidified themselves as third-favorites, behind the Dodgers (+175) and Padres (+375), but well ahead of the Brewers (+833) and Braves (+1067).
• May 25: The Brewers ( +1233) have improved steadily over the course of the season thanks to dominant starting pitching from Brandon Woodruff, Corbin Burnes, and Freddy Peralta, who are all sporting ERAs below 2.60.
• Apr. 6: Early injuries, specifically to MVP contender Fernando Tatis Jr, have sent the Padres’ odds from +422 to +463.
• Feb. 10: Acquiring Trevor Bauer has led to the Dodgers’ odds improving from +200 to +177, while division rival San Diego faded from +375 to +422.
• Oct. 28, 2020: No surprise in the opening NL Pennant odds: the LA Dodgers are +200 favorites to win their second in a row and fourth in five years.
