Nevada sports books lost a record $11.4 million on baseball in November after bettors cashed on the Astros beating the Los Angeles Dodgers in Game 7 and on futures wagers on Houston to win the World Series. It was the largest baseball loss ever suffered in a month by the state’s sports books, according to Michael Lawton, the Nevada Gaming Control Board’s senior research analyst. The books’ previous record baseball loss was $6.2 million in November 1999, when bettors cashed their winning tickets on the New York Yankees following their World Series sweep of the Atlanta Braves. The state’s casinos won $909 million overall, including $274.7 million on penny slots.
