There's more to it than that.
They were having trouble winning in the U.S., too. Thing are different now.
I'm not saying they'll win (though that's what I predicted). I'm just saying people are giving too much weight to the location of the course, IMO.
I do pull clubs from time to time based on the course. Earlier in my life I pulled ALL of my woods (they were persimmons as well as my 3 and 4 irons until I could feel good with the other clubs. Almost a year before I put them back. It was done for confidence, rather than score, as the over all score did not really change over that year.
Half an hour doing putting drill, then off for 9. The score of 46 falls within my average for this course. Good off the tee with 5 fairways and no smacks into real high ruff or OOB. Most putts were 2 -3 but one hole at 4 was a real disaster, long 30' first putt, left it fairly short by misreading up hill slope, rimmed out the third putt leaving me 6" for the triple bogie. Short game better than last time. Still, the fun factor was mostly there. Made 2 par threes, no birdies. Mostly bogies and a few doubles. Lots to work out at range tomorrow!
