I'm surprised that nobody on this thread hasn't or doesn't play against some of those women. How they faired against them would carry some weight for discussion.
The closest I know of is a scratch golfer I know played a few rounds with a college player that did play in the US Women's Open and I heard she had a good first round but I never heard anything after that so I would assume she probably missed the cut or didn't do too well.
The scratch I know was very impressed with her game and said she hit the ball almost as long as he did (but that doesn't tell me much either)...But he did beat her by a stroke or two each time.
Not much to go on since it's hearsay and I don't even know that she was completely focused during their rounds. Plus I really don't know how good she really is.
Surely somebody else has a first hand experience that could give a clue how well they would play against men.
