AL East Divisional Odds

Odds as of Sep. 6, 2021.

• Sep. 6: Tampa now has a 7.5-game lead with fewer than 30 games remaining, leading to their odds reaching a season-best -1250.
• Aug. 31: Despite the Yankees going on a tear in late August, Tampa has kept New York at bay and shortened to -650. The lead by seven games with 31 to play.
• Aug. 22: Tampa shortened to -225 as Boston implodes. New York is now the +250 second-favorite.
• Aug. 16: Boston has righted the ship to an extent, winning three in a row and improving from +400 to +330. But the Rays (-185) have a 3.5-game lead with 43 games to play.
• Aug. 11: Boston’s freefall continues. Their odds faded from +225 to +400 over the last three days.
• Aug. 8: Tampa is an odds-on favorite (-115) for the first time this season and it’s somewhat surprising they aren’t shorter, holding a three-game lead on Boston and 5.5 on New York.
• Aug. 2: The Rays have taken over the division lead by the slimmest of margins; same goes for the odds with TB at +105 and BOS at +135.
• July 19: Boston is now a slight -117 favorite over Tampa (+137), clinging to a half-game lead.
• July 5: By going 9-1 in their past ten, Boston has opened up a 4.5-game lead in the NL East and is now a -150 favorite.
• June 27: The Rays (+149) and Red Sox (+195) are within half a game at the top of the division, but oddsmakers like the Rays a lot more, likely because their run differential is nearly twice as good (+85 vs +42).
• May 25: The Yankees (-113 on average) still lead in the odds, but the Rays and Red Sox are ever-so-slightly ahead in the standings.
• Apr. 7: All five teams are within a game of each other after a week, but NYY continues to be a heavy favorite at -198, on average.
• Feb. 10: TOR (+368) is second-favorite to NYY (-190) after acquiring George Springer.
• Jan. 25: The Yankees have opened as heavy -200 favorites to take back the AL crown from the Rays in 2021.

AL Central Divisional Odds

Odds as of Sep. 6, 2021.

• Sep. 6: The White Sox haven’t officially clinched, but the AL Central odds are off the board. Chicago’s lead is at 9.5 games with just 25 games left.
• Aug. 31: Cleveland (+15000) has climbed back to .500 but still trails Chicago (-50000) by ten games.

• Aug. 8: Same same but different in the AL Central. Chicago is 10.5 games up and these odds will be off the board soon enough.
• Aug. 2: Chicago is still 8.5 games up and as short as -10000 at some sportsbooks.

• June 27: With a 2.5-game lead over Cleveland (and double-digit lead over the rest of the division), Chicago is a massive -561 favorite (shortest divisional odds of any team in baseball at the moment).
• May 25: The White Sox are only 1.5 games ahead of Cleveland, but are now prohibitively short -352 favorites.
• Apr. 7: CHW has been hit by some significant injuries and started just 3-3, leading to their odds fading from  -146 to -116.
• Feb. 10: CHW has shortened to -146 while second-favorite MIN faded to +177.
• Jan. 25: The White Sox are -128 favorites to win their first division title since 2008.

AL West Divisional Odds

Odds as of Sep. 6, 2021.

• Sep. 6: No one saw this coming. The Mariners have overtake the Athletics for second in the division, but they remain third in the odds at +3000. Houston is 4.5 games ahead of the field and a massive -1900 favorite to hold on.

• June 27: A recent 11-game win streak put the Astros two games up on Oakland and sent their odds to -216 on average. The A’s are at +170.
• May 25: Yet again, this is shaping up as a two-team race between the Astros (-113) and Athletics (+101). The third-place Mariners are already 5.5 games off the pace.
• Apr. 7: The still-undefeated Astros (+157 to -125) and still-winless Athletics (+123 to +218) have seen some of the biggest early divisional-odds movement.
