Hi wardy,
All tournaments on WGT adhere to USGA tie-breaking rules.
In the event of a tie, the better scoring entrant between or among the
tied entrants will be the entrant with the lowest combined score for
the final nine (9) holes of the Game. If any ties remain, the better
scoring entrant between or among the remaining tied entrants will be
the entrant with the lowest combined score for the final six (6) holes
for such Game. If any ties remain, the better scoring entrant between
or among the remaining tied entrants will be the entrant with the
lowest combined score for the final three (3) holes for such Game. If
any ties remain, the better scoring entrant between or among the
remaining tied entrants will be the entrant with the lowest score for
the 18th hole (9th for nine hole games) in such Game, and any
remaining ties will be determined by identifying the lowest scoring
entrant for each individual game hole, in sequence from 17th (8th for
nine hole games) through to 1st, as is necessary to determine a winner,
and if any ties remain at that point, the earlier-submitted entry
between or among the tied entries will be deemed the better scoring
entry.
