Rafael Nadal's French Open semifinal match with Alexander Zverev was headed toward a second set tiebreak before Zverev rolled his ankle in excruciating fashion.
The world No. 3 had to retire from the match immediately, giving Nadal the win and a spot in the championship match.
How did sportsbooks handle Zverev’s retirement? It's complicated.
For certain types of wagers, such as game spreads, set spreads and totals, it would be impossible to determine a winner as the match was not completed.
But for markets in which the result had already been determined — such as the winner of the first set — those bets all stood.
What about moneyline wagers?
A DraftKings spokesperson said the sportsbook’s house rules stipulate that all bets on this type of contest would ordinarily be voided.
But, for this instance, DraftKings has elected to pay out all Nadal moneyline wagers and void losing Zverev tickets.
Per FanDuel's official rules page, all matches that are completed at the Grand Slam level and have a retirement that occurs after the first set will result payouts for the winning player and bets voided for the losing party.
PointsBet also maintains a rule in the moneyline market stating that if a player withdraws after the first set is completed, betting tickets on the winning player will be paid out while tickets on the losing player will be void.
