The best OVER/UNDER ballparks are the most important betting nugget when digging into MLB stadium trends. 

Below, we break down which parks have lent themselves to OVER/UNDER bettors this season, and how you can take advantage of the data.

2024 Best OVER Ballparks In Baseball

Marlins Have the Best OVER Park

Somehow, the lousy Marlins have hosted the most consistent OVERs in baseball. This pop certainly isn't coming from Miami's offense, so we can turn to their weak run prevention to tell the story. The Fish have allowed 255 earned runs (5.07 ERA) at home this season. Ew.

Mariners Host Most UNDERs

By nature, T-Mobile Park in Seattle is famous for turning homers into warning track flyouts, so it's no surprise to see it rank among the best UNDER parks in MLB. But its status as the sole best UNDER park must be attributed to the Mariners' terrible offense this season. It's truly a team effort between club and park, as Seattle's .636 OPS at home ranks second-worst in all of baseball, behind only the Chicago White Sox, who are basically a Triple-A team.

Best OVER Ballparks – Last 5 Years 

Truist Park is a haven for runs. It’s been the second-best OVER park in 2024, and it’s been top five through the last five seasons. This may have less to do with the Reds' offense and more to do with the park's tiny dimensions, but the trend has stuck nonetheless.

Is Coors Field Actually An OVERs Park?

While Truist has been the home for run scorers, Colorado’s Coors Field is often cited as the most offensive park in baseball. But, it’s actually been one of the worst parks for OVER bettors in recent years.

In the last five seasons, Coors ranks as the ninth-least profitable park for OVER bettors in baseball, with a 104-116-7 record. If you had bet $100 on the OVER on every game at Coors, you would’ve lost $2,108.49 during that time. This park consistently sees totals well over 10 runs, so maybe check your anti-Coors bias and sprinkle the Colorado UNDER from time to time

How To Bet On MLB OVER/UNDERs

There are three main ways to bet on MLB, in the form of moneyline betting, runline betting or total runs. To take advantage of this ballpark OVER/UNDER data, you’ll have to focus on that third option, run totals.

In an MLB run total bet, you’re betting on whether both teams will combine to score OVER or UNDER a set number of runs in a game. At the sportsbook, you’ll notice MLB OVER/UNDER odds are listed like this for a fictional Jays/Twins game:

In this example, if you believe that the Twins and Jays will combine to score OVER 8.5 runs (if the score is, for example, 5-4 Toronto), you would win $190.91 on a $100 bet – your initial $100 wager plus $90.91 in profit.
