I watched the final holes. I would like to say that the caddies of both players did a very professional job.
On 17 Jay was insecure standing over his approach. His caddie did a great job convincing him he did not have to hit that flag. Just get it on the green. His words put Jay back on track. He went on to hit a decent stock iron that landed for a reasonably safe par.
On 18 in regulation it was Hunters turn to start fixing. Jay was within 10 feet, one shot ahead. Hunter needed a birdie to stay in the game. He picked a 9. For some reason he switched for an 8. In all fairness that switch may have been since the caddie distracted him by talking about the yardage to go over the bunker. Who wants to go in the bunker? The caddie told him to put back the club & start over. So he did. Convinced Hunter that a 9 was the right club. They decided on a 9 that the caddie told him to hit full & hard. So he did & got it within Jay. Got his birdie & a ride back to 18th tee to eventually post another birdie and win.
I agree with Yoda regarding the players being so hard on themselves. Jay was in on an invitation. He won a small fortune, earned a great experience of being under the gun & secured his card. That should be a great accomplishment for anyone. After a good battle like that - I'd like to hear not just the winner saying:
