Owner of the Gallery furniture retail chain James Franklin McIngvale, more commonly known as Mattress Mack, has just made sports betting history. McIngvale recently placed a $10 million wager on the Houston Astros defeating the Philadelphia Phillies in the 2022 MLB World Series, successfully earning a whopping total of a $75 million cashout: This is reportedly “the largest payout on a single legal sports bet in United States history,” according to official records. Houston gained a well-deserved 4-1 victory over their competitors this past Saturday, November 5, 2022, giving not only McIngvale, but the entire MLB community something to celebrate.
