How 'Bettor X' made it a wild World Series in Las Vegas

A big bettor went undefeated, running from Las Vegas sportsbook to sportsbook, placing multiple six-figure wagers with little regard for the odds. A furniture salesman from Houston hedged a promotion that would cost him $10 million in refunds with big bets on the Houston Astros. And ticket brokers attempted to lay off the risk of losing millions of dollars in potential profits, if the series didn't reach Game 7.

Big money was everywhere in one of the craziest World Series from a gambling perspective that Las Vegas has ever seen.

Night after night, game after game, Las Vegas bookmakers loved their position on what turned out to be the most heavily-bet World Series ever. With all the large bets floating around, they were able to adjust the odds to attract money on whatever side they needed. They had the best of it, at least they thought.

"I had myself in some really terrific spots, just great, great positions," Johnny Avello, executive director of the Wynn race and sports, told ESPN on Thursday afternoon. "Unfortunately, I didn't win any of them."

Official numbers won't be released until the end of the month, but it's safe to say that tens of millions of dollars were wagered on the World Series at Nevada sportsbooks -- a lot of it by one unnamed bettor who went on a weeklong run that will go down in Las Vegas lore.
