The mysterious let-it-ride gambler who won $14 million betting on the 2017 World Series cashed in again at Super Bowl LII.

Bettor X, as the man has become known, walked away with at least $10 million after placing multiple wagers on the Philadelphia Eagles, according to RJ Bell of the Associated Press.

MGM, William Hill, CG Technology, and the South Point all reported taking money-line bets from Bettor X, according to told ESPN's David Purdum. Johnny Avello, executive director for Wynn Race and Sports, told Purdum he also took a "good-size, six-figure" money-line bet from Bettor X.

"He's one of the guys who was floating around betting all that money on the World Series," veteran Las Vegas bookmaker Jimmy Vaccaro, now of the South Point, told the Associated Press. "I don't think he lost a bet then. We'll see how he does now."
