Clark really stood up and handled the pressure and finally got the chocolates. Xander has won what, 5 PGA events? And the Olympic gold. Still young; he's going to win more as his game is solid.
For me, the real story was Adam Scott, again. Good on him for getting well into contention. But OMG! Some of the errors he makes for a player with the swing from heaven - still getting VG distance too - and improved (?) putting/wedges. Hard to believe.
After the 32m drive into a tree leading to a bogey in Rd.3, then stuffed the 1st in Rd. 4 by hitting into bunker, bunker, then missed a 2ft putt for another bogey. Adam, get serious if you want to win a PGA event. If so, come out ready to fire up after both hitting and putting warm-ups. You know the course very well. Stop the dumb mistakes! Shouldn't be suffering too much from nerves by now.
Then on the driveable 16th, with a chance of moving up into 2nd or 3rd, hit a great 3wd onto front of the green, only to putt it totally off into the rough left side. Poor pitch back, missed the putt - bogey when should have had at least a certain birdie.
I know many of these courses must be very tough and TV reduces the gradients etc. But Adam, time's running out. If you can't apply knowledge, experience and skills when it really matters now, you won't just get lucky!
