Nevada Gaming Control Board Voids Bellagio Past Posted Korean Baseball Bets

  • A past posting situation on Korean and Chinese baseball could have cost the Bellagio sportsbook in Las Vegas almost $250,000.
  • Due to incorrect start times posted on games bets were accepted up to two hours after they began.
  • The Nevada Gaming Control Board has reportedly ruled that the outstanding bets can be voided.

Remember earlier this month when the Bellagio took a big hit on past posted Korean baseball games? Here’s how we reported it at the it happened:

There’s a reason that live odds feeds are so fastidious about updating and reporting time changes. Last weekend, incorrect start times posted on Chinese and KBO league Korean baseball games resulted in nearly a quarter million dollars worth of winning wagers to be placed at MGM Resorts sportsbooks in Las Vegas well after the games had started. Long time bookmakers and sports betting experts suggest that it might be the biggest past posting loss in Las Vegas history. Most of the 50 or so bets were placed on self service kiosks at the Bellagio Hotel & Casino between 1:30 AM and 3 AM Pacific Time. The games in question started at 1 AM and 2 AM Pacific.

MGM Resorts got some good news this week according to a report in the Las Vegas Review Journal. The word is that the Nevada Gaming Control Board has decided that the bets in question should be voided. This includes $200K worth of parlay tickets that MGM is no longer on the hook to pay. The essential David Purdum at ESPN originally reported on the Gaming Control Board’s decision and had this to say:

BetMGM on Tuesday declined comment regarding the Nevada Gaming Control (NGC) decision. A spokesperson for Nevada Gaming Control said they have no comment.

At least two of the bettors believed to be involved confirmed to ESPN that the bets are being rescinded.

There isn’t a hard and fast prohibition against past posting in Nevada gaming regulations. MGM sportsbook house rules have no specific language against past posting though the race book does. The MGM house rules did have some conflicting verbiage regarding what happens in the event of an ‘obvious error’ though there is no clear definition of the term ‘obvious’. Unfortunately, since state gaming regulators nor the MGM are talking about it publicly there’s no way to determine how the decision to void the outstanding bets played out.

UPDATE: A spokesperson for BetMGM has confirmed this according to an article in the Las Vegas Review Journal:

“I can confirm that we’ve now received word from the NGCB that it has approved our request to rescind and refund the past-post wagers.”
