Last season, Jim "Mattress Mack" McIngvale caused quite a stir with his seven-figure bet on the Houston Astros to win the World Series. This year, a Boston Red Sox backer has taken over for "Mattress Mack."
According to ESPN's Darren Rovell, an anonymous bettor used the DraftKings mobile app in New Jersey to place a $500,000 wager on the Sox to beat the Los Angeles Dodgers in the World Series. DraftKings officials confirmed the bet is valid.
The reported payout for the bet would net the deep-pocketed punter $325,000, meaning he or she played the Sox at -154.
Rovell reported it's one of the largest bets in DraftKings' young history.
The Red Sox are currently -148 favorites to win Game 1 at DraftKings, and the over/under is set at 7.5 runs.
The World Series begins Tuesday night at 8:09 p.m. ET on FOX.
