Ties are broken only after play is completed. Until that time, same scores are ranked by time of finish and are not officially placed. 

 

USGA recommended tie breaking is used: card review of the last nine, last six, last three, last hole.  

 

If -- in the final leaderboard, after all scoring is complete by all golfers -- you see more than one person or team with the same final score, but the "Position" column shows one of them finished higher than the other, that is a result of the application of the tie-breaker method.

 

And, if you see a hyphen ("-") instead of a number in the position column for a player or team in the gross leaderboard, they finished at that position or higher in the net leaderboard.  And vice versa.
