MLB Betting Trends: Best and Worst Teams to Back in August 2025
Baseball has seen the trade deadline pass, and if you review the standings, we are inside of 50 games left in the regular season. Patterns on all teams have been established. Yet, we know this is where every game matters for playoff contenders, with the results far from guaranteed. Here is our latest monthly update in various categories for betting on baseball.
Most Profitable MLB Teams to Bet On
#1 Milwaukee 68-44 +20.2 units
#2 Toronto 66-46 +14.4
#3 Miami 55-56 +13.1
#4 L.A. Angels 55-58 +7.8
#5 Chicago Cubs 65-47 +7.1
Notes: What a charge Milwaukee has made to not only being the best team to bet on but having the best record in the majors. (Those two elements don’t necessarily go hand and hand.) The Brewers are #4 in run prevention, #2 since June 1 in starting pitcher ERA, and #5 in scoring. Sounds like a team to possibly back almost daily. Milwaukee’s surge has surpassed what Toronto accomplished just before them, with the Blue Jays flying into first place in the AL East. Toronto’s rise came when they started to hit home runs, as they have gone from the bottom 5 to the middle of the pack for long balls. Miami is a genuine surprise in a year where Milwaukee has emerged as the lone dominant club (though only 7th-best World Series odds). The Marlins’ pitching has improved dramatically, ranked #3 in run prevention since the middle of June. Miami is no longer an easy out. The Angels are tied for the third-worst run differential in the AL, yet are a profitable wager. (Head shaking side to side) A 20-13 record in one-run games is a big part of the answer. The Cubs hang around in the Top 5 but are not as imposing at this time.
Least Profitable MLB Teams to Bet On
#30 Atlanta 47-66 -42.5 units
#29 Colorado 30-82 -30.0
#28 N.Y. Yankees 60-53 -21.1
#27 Minnesota 52-60 -16.6
#26 Arizona 54-59 -18.5
Notes: When your entire starting pitching staff from opening day is on the IL, that is not a good sign. Atlanta passed Colorado like they were standing still and is easily the worst bet in baseball. With the #21 rated offense, this does little to help the Bravos pitching. We’ve poked fun at Colorado all year; nonetheless, they’ve dropped just over two units the past two months. Yankees fans have turned on the Pinstripes, and unless something changes quickly, there could be many changes forthcoming for the squad in the Bronx if they keep failing. With no – official – white flags waving at Target Field, after the trade deadline, the Twins are as thin as the shopping lines at Target. It could be a rough last 50 affairs in the Land of 10,000 Lakes. Arizona has plummeted for bettors, and after moving several assets, betting against the Snakes will likely gain momentum.

Top MLB Teams to Back the Over
#1 Toronto 60-47 (pushes not listed) +8.4 units
#2 Washington 59-48 +5.5
#3 Seattle 59-49 +5.1
#4 L.A. Angels 59-50 +3.1
Notes: Toronto has made a big push to climb to the top of this list because its offense has moved up to #8. The Blue Jays were hanging around the Top 10 most of the season because the pitching is inconsistent at #23. It’s hard to say Washington is truly a good OVER wager because other than a stretch of 14-1-1 OVER from June into July, on balance, they would not be ranked this high. The average Seattle contest is roughly nine total runs, yet the Mariners have been at 9 or higher total only 26 times by sportsbooks. That explains why they are #3. The Angels are #25 in runs given up, and they score enough, often enough, to lean OVER.
Top MLB Teams to Back the Under
#1 Cincinnati 67-42 +20.7 units
#2 Tampa Bay 65-44 +16.5
#3 San Diego 64-45 +14.3
#4 Pittsburgh 64-46 +14.2
Notes: When comparing the two totals’ charts, four clubs make as many as 3-units profit for Overs, compared to 14 that reach the same threshold for UNDERs. Leading the way is Cincinnati, which has remained in the Top 8 all season for run prevention. The Reds are #10 in scoring, but playing in a small park is conducive to scoring, and the oddsmakers have to consider the possibilities, if not always the results. Tampa Bay playing outside at home lends itself to the perception of more runs, but not the outcomes. The Rays have generally been an UNDER club for years, and that remains so. Petco Park has always played like an UNDER waiting to happen. The Padres’ resurgent pitching (#5 in fewest runs since June 1) makes that happen. Pittsburgh has a few good starting pitchers and is last in scoring. Enough said.
Top Run Line Betting Teams This Season
#1 Miami 58-43 +16.6 units
#2 Toronto 64-50 +11.4
#3 Boston 64-50 +11.3
Notes: Miami has hung around in a lot of matches, winning as underdogs or keeping the games tight. That is why they lead this category. The surges by these two AL East foes have them not only beating teams with regularity, but doing so decidedly. That is why the Blue Jays and Red Sox are listed in these slots.
Worst Run Line Betting Teams This Season
#1 Atlanta 44-67 -25.2 units
#2 San Francisco 48-65 -19.7
#3 Baltimore 52-61 -19.5
Notes: Atlanta is -24 in run differential. Despite this, the Braves are an incredible Play Against outfit on the run line. Atlanta is 6-15 as ML favorites and 2-9 as underdogs (4-7 on RL) of late, dropping like an anvil. San Francisco stopped hitting as of June 1 (#26 runs scored), not allowing them to win or cover spreads. Baltimore’s plight is essentially the same as the Braves, just with a few fewer setbacks.
