Which MLB teams are most, least profitable for bettors?

We're already through two-thirds of this MLB season, and some teams have emerged as clear cash cows for savvy bettors. Others have provided nothing but disappointment - which can be a boon for those playing the other side.

Here's a list of the 10 most and least profitable teams as of Tuesday, per Sports Database, along with their record and their cumulative return on $100 bets:

Most profitable teams

San Francisco Giants (71-41, $2,808)

The only 70-win team in baseball has also been by far the most profitable, returning nearly 30 times the investment on $100 bets throughout the season. The Giants have been consistent winners, too, netting large positive returns in every month of the season.

Seattle Mariners (58-54, $1,714)

The Mariners own the dubious distinction of having the worst run differential (minus-51) of any team with a winning record. Unsurprisingly, they've also been MLB's most profitable underdog play on the season, returning $2,042 with a 47-43 outright record when priced as a 'dog.

Detroit Tigers (52-60, $829)

The Tigers are the only team in the top 10 with a losing record, which speaks to how efficient Detroit has been with its few wins. The key is coin-flip games: The Tigers are 24-14 with a $1,187 return when priced between +125 and -125, which is the most profitable run by any team in that spot.

Least profitable teams

Arizona Diamondbacks (35-78, -$3,527)

It's been a season from hell for the Diamondbacks, who at one point lost 17 consecutive games and an MLB-record 24 straight on the road. Arizona lost bettors roughly $2,000 in May and in June, and the D-Backs are off to a 2-6 start to August with nothing left to play for.

Minnesota Twins (48-65, -$2,624)

The Twins aren't the worst team in baseball, but they're easily the most disappointing. Minnesota entered the year as a title contender and quickly fell by the wayside with a 12-24 start to the season. The Twins have also posted a 29-34 record outright with minus-$1,942 returned as a favorite - nearly double the amount lost by the second-worst team in chalk spots.

New York Yankees (62-50, -$1,003)

Condolences to anyone who placed faith in the Yankees, a team that's somehow lost bettors more than $1,000 despite owning the 10th-best record in baseball. The primary culprit? Losing in big spots. New York has been priced as a -230 favorite or higher 10 times - fourth-most in MLB - and owns a miserable 5-5 record with $750 lost in those 10 games alone.
