My home course! And frankly having faced the occasional "wrath of Wilshire" I can say that the course can play so many different ways.
Wilshire is a demanding golf course, but very getable for professionals, especially the women at only 6,500 yards. The narrowest fairway is ~30 yards wide and most are considerably more, sometimes double. Off the tee for LPGA players it is really not a challenging course, but for the average golfer it is a fair but stern test.
And hitting the fairway is very important because most of Wilshire's defense is in the approach shots. Nearly every hole has somewhere that you cannot miss, otherwise bogey or more is likely. But with a few exceptions depending on pin position, there is a place to miss and leave a very reasonable opportunity for par.
The women are facing very difficult wind conditions, and with much less repeat play out there than a member many are missing it in exactly the wrong spot. The course condition is perfect (shoutout to Brian Sullivan), but perhaps there were a couple hole locations selected that the LPGA did not have the wind in mind for. A small increase in speed and firmness can go a long way in adding to the difficulty.
Even so, I'm seeing the talent on full display from the players and it's clear there is opportunity to go around the course successfully and be rewarded for excellent shots. Wilshire played as difficult as is possible yesterday (well, with a couple tees up) for the LPGA, and the leader shot 64!
Some approach spots you cannot miss (holes numbered for tournament, 18 normally is 10), * denotes expected wedge approach
1*: long, severe back to front but open in front
5: left, catcher's mitt green so easy to stay away
7*: long left
8*: long
9: right or long
10*: long or right
11: long or left
12: maybe nowhere to miss that is easy... good par 3
13*: long or left
14*: long or short side
15*: long left or short right
16*: short right
17: short left or long right
18: long or left when back, short right when front
As you can see, long is often not the place to be. I think the firmer greens are really punishing overly aggressive shots.
