Hainan Classic presented by MAEXTRO End of Round 1 Leader

The market resolves when the tournament operator posts the official Round 1 results and the exchange applies its resolution rules; that typically occurs after all scoring is verified and any official scorecard adjustments are completed. Check the exchange’s event page for the exact resolution timing and source.

The End of Round 1 Leader is the player listed by the tournament as having the lowest official 18-hole score at the close of play for Round 1. If the tournament’s official leaderboard shows a tie for the lowest score, the market’s resolution will follow the exchange’s published tie-handling rules and the tournament’s official scoring.

Each outcome generally corresponds to an individual player in the tournament’s starting field (or any named entry the market lists). The number reflects the players included in the market at listing; some markets also include placeholders for late additions or an 'Other' category depending on how the market was structured.

If a player withdraws before teeing off, the exchange may void or remove that outcome per its rules; if a player withdraws during play and does not complete 18 holes, they cannot be the official Round 1 leader. For precise handling of withdrawals and refunds, consult the market’s terms and the exchange’s operations policy.

Tee times matter because early groups may face different wind, temperature and course firmness than later groups; rapidly deteriorating or improving weather can create scoring disparities between early and late starters. Traders watch official weather forecasts, live scoring and tee-time groupings to reassess which players are likelier to post leading scores as the day progresses.
