Rapper Jay Z has made good on his boxing bet after losing a $100,000 (£62,500) wager he made with retired sportsman Oscar de la Hoya on the outcome of his Roc Nation Sports fighter Miguel Cotto's big bout with Canelo Alvarez. Cotto lost Saturday's (21Nov15) title fight in Las Vegas by unanimous decision, and the hip-hop superstar has already paid up. "Thanks to Jay Z, thousands of patients at White Memorial Medical Center (in Los Angeles) will also be winners," Oscar tells TMZ.com. "I don't imagine (Jay's) excited about losing $100k, but he can take some comfort in knowing that it's going to a good cause."
