LAS VEGAS – Nobody would have given odds on this. Inside the glittering casinos that line the Las Vegas Strip, the slot machines were turned off and the sportsbooks were dark. Oddsmaker Jay Kornegay would be in the middle of it all at the Westgate Las Vegas, one of the most popular sportsbooks to watch March Madness. But the massive hotel, like all others in Las Vegas, is closed because of the new coronavirus and the huge televisions in the sportsbook are dark. Oddsmaker Jimmy Vaccaro said it didn’t make much sense to offer betting online when only obscure sports in faraway places are available to wager on.
