William Hill U.S. confirmed the bet was placed on Wednesday afternoon at the SLS Casino in Las Vegas, the same sportsbook where Adducci placed—and then cashed—his first bet. Michael Grodsky, William Hill's VP of marketing, said Adducci flew to Vegas and placed the bet on Wednesday. Adducci said he flew out Tuesday from his hometown La Crosse, Wis. He called Grodsky to let him know he was in Vegas, and after about a day or so of collaborating, William Hill officials confirmed the odds and the amount they'd allow Adducci to bet.
