Odds to Win 2025 American League Pennant

2025 American League Pennant Odds Movement Timeline

• October 21 – The comeback is complete! After dropping Games 1 and 2, the Blue Jays came roaring back to win the ALCS in seven games and move on to the World Series.
• October 20 – We’re getting a Game 7! Toronto held court at the Roger Centre last night to force a decisive and final elimination game against Seattle for the AL Pennant. The Blue Jays are now averaging -130 to advance to their first World Series since 1993, while the Mariners are getting +110 to reach their first World Series ever.
• October 14 – It goes without saying: losing your first two games of the LCS at home will tank your pennant odds. After dropping Games 1 and 2 in Toronto to the Mariners, the Blue Jays are now averaging +475 to make it to the World Series.
• October 9 – Going into their ALDS Game 5 on Friday, the AL Pennant odds for the Mariners (+274) and Tigers (+283) are basically dead even, with Toronto (-124) still favored over the winner.
• October 7 – After clobbering the Yankees twice in Toronto, the Blue Jays (+145) are the new favorite to win the AL Pennant.
• October 3 – The Yankees are the new favorite to win the AL Pennant, but just barely: New York is averaging +191, just ahead of Seattle’s +199.
• September 29 – Is this the year the Seattle Mariners finally win the AL Pennant? Sportsbooks sure think so, with the Mariners getting as short as +185 to take the league title.
• September 12 – The Tigers and Blue Jays are neck and neck at the top of the odds table as they fight for the AL’s No. 1 seed in the playoffs. Detroit’s average odds of +312 is just ahead of Toronto’s +345.

2019 American League Pennant Odds

Top Contenders

Oct. 8: Even though the Yankees are through to the ALCS already, while the Astros are still battling Tampa in the ALDS, Houston is -180 and NYY is +150.

Oct. 2: There’s been a narrowing of the odds between ALDS opponents NYY (+220 to +250) and Minnesota (+750 to +710) ahead of Game 1.

Sep. 30: The A’s saw their pennant odds improve the most over the final week of the season (+970 to +870) as they locked themselves into the first Wild Card spot and will host the Rays (+1200) on Wednesday, Oct. 2nd.

Sep. 27: The Indians have fallen two games back of a playoff spot with just three to play. Their AL Pennant odds have sunk to +3200, which isn’t nearly low enough.

Sep. 23: With just a week to play, the A’s (+1000) hold a two-game lead on the Rays (+1400) and Indians (+1500), and their pennant odds reflect their current edge.

Sep. 9: A bad week has put Cleveland (+1500) a step behind the other two Wild Card contenders, Tampa Bay (+1300) and Oakland (+1400).

Sep. 3: The three teams in the AL Wild Card race (Rays, Indians, Athletics) are separated by just 1.5 games in the standings, but have rather disparate pennant odds, ranging from Cleveland at +1200, to Tampa at +1300, to Oakland at +1700.

Aug. 26: The Astros are at a new season-best in terms of pennant odds, going from +100 to -120. It’s the first time all year that an AL team has been shorter than even money.

Aug. 19: The Red Sox (+3500) are all but finished. They are 6.5 games out of a Wild Card spot and are now without Chris Sale, likely for the rest of the season.

Aug. 9: The separation between the Astros (+100) and Yankees (+190) on the one hand and the next tier of contenders — Indians (+800), Twins (+820), Rays (+1400) — is bigger than ever.

Aug. 2: Splashy trade-deadline acquisitions of Zack Greinke, Aaron Sanchez, and Joe Biagini, coupled with inaction from the Yankees, has launched the Astros to the top at even money.

Jul. 29: Minnesota continues to plummet (+510 to +650), joined by the slumping Rays (+1200 to +1400) and back-to-earth Rangers (+3600 to +12300).

Jul. 19: The Twins’ odds have fallen from  +340 in early June to +510 in mid-July. Not only are they playing mediocre baseball, but the rival Indians have almost caught them in the AL Central.

2019 National League Pennant Odds

Top Contenders

Oct. 2: After knocking out the Brewers in dramatic fashion, the Nationals’ odds to win the NL went from +740 to +470.

Sep. 30: St Louis hung onto win the NL Central and their pennant odds got a boost because of it (+590 to +560), while the Brewers, relegated to facing Max Scherzer in the Wild Card game (Oct. 1), fell from +820 to +1100.

Sep. 27: The Cardinals (+590) and Brewers (+820) are separated by just one game at the top of the Central. Winning the division would be a huge boost in their quests for the NL Pennant.

Sep. 23: The playoff picture is all but finalized. The Dodgers (-120) and Braves (+300) have clinched their divisions; the Cardinals (+560) are going to win the Central, and the Nats (+870) and Brewers (+1000) will play in the Wild Card, home-field TBD.

Sep. 3: The playoff field may be set in the NL with the Cubs holding a 2.5-game lead on the Phillies for the final Wild Card with about 25 games left to play. After Chicago (+1100) there’s a steep drop in the odds to the Phillies (+2200) and Mets (+2400).

Aug. 26: The Nationals continue their steady assault on the odds, this time improving from +940 to +730.

Aug. 2: Shoring up their awful bullpen at the trade deadline led to the Braves gaining ground on the Dodgers, going from +440 to +340.
