Sunday’s lucky 10-team Korean and Chinese baseball parlay, which paid out more than $137,000, might not have been so lucky after all.
The Nevada Gaming Control Board has opened an investigation after discovering that the baseball games had already started before the wagers were placed, according to ESPN’s Doug Kezirian.
BetMGM incorrectly entered the start times for the games, allowing multiple bettors to get in on the action at self-bet kiosks between 1:30 a.m. and 3:00 a.m. PST on Sunday.
Casino officials noticed the errors on Sunday afternoon and stopped payments. The number of bettors to successfully cash tickets is currently unknown. All four KBO games began at 1:00 a.m.
“A trading error was identified this weekend and addressed. We’re working with Nevada Gaming authorities on this matter,” according to a ROAR Digital statement provided to ESPN. ROAR manages BetMGM properties.
There were more than 50 questionable wagers in question, according to ESPN. The timing error could cost the book nearly $250,000 overall, including the 10-team parlay that netted $137,000.
If Nevada Gaming deems the wagers invalid, the remaining tickets would not have to be paid out. Timing mistakes happen annually at sportsbooks, but repercussions are generally not this drastic.
According to ESPN’s conversations with several Nevada sportsbook executives, books generally offer to refund the tickets and allow the bettor to continue as a patron or they pay in full and ban the bettor permanently.
The 10-team parlay seemed too good to be true. Nearly every leg cashed with ease, which is rare with a parlay of that magnitude.
The NC Dinos (-110) and the ‘under’ 9 runs in their game against the Doosan Bears was televised on ESPN. NC broke a scoreless tie in the fifth inning with a three-run homer at 2:28 a.m., which allowed bettors to jump on those wagers at that point due to the start time being incorrectly entered at the self-bet kiosks.
Another easy leg of the parlay came in the ‘over’ 9.5 runs between KT Wiz Suwon and Hanwha Eagles. Suwon scored five runs in the first inning and Hanwha added two in the second frame to put the ‘over’ in great shape.
The Uni Lions (+150) scored runs in five of the first six innings to jump out to a 10-2 lead. It was the only game in the parlay from the Chinese Professional Baseball League.
