4th round scoring average for Pinehurst #2
Men 72.40
Women 72.39
For that matter the third round was 73.82 vs. 73.30 which indicates that Mike Davis, love him or not, accomplished exactly what he set out to do with these course setups. He wanted to use the same hole locations and achieve the same scoring round for in both Championships.
Of course in the first two rounds, scoring parity was not achievable due to the humongous different in depth of the fields prior to the cut. The 150th ranked women's player is much weaker relative to the top women than the 150th men's player is relative to the top men, in my view.
