Padraig Harrington shot a stunning 64 to smash the course record and rise to the top of the standings after day one of the senior PGA Championship.
The 51-year-old carded a bogey-free round to shoot eight-under par and holds a two stroke lead at the top of the leaderboard.
A week on from finishing in a tie for 50th at the PGA Championship, Harrington started brightly and nailed a long-range Birdie putt on the Par-4 second to get his round up and running.

The three-time major winner chipped in for a Birdie on the 10th and kept his foot on the gas to set a new course record at the new Texas HQ of the PGA of America.
"It was a good day," Harrington said. "Everything worked well. Hit the ball well off the tee, particularly straight off the tee, which helps. I think I holed a couple of putts at the right time.
"I don't expect it to be like this now the next three days, but it was an easy 64. In some ways, the reason it was an easy 64 is because when you're playing with somebody like Rocco, there's always a bit of chat, and there's always a bit of fun going on, so you're quite relaxed.
"And that really does make a difference to how you feel about your shots and things like that. So it's something as professionals we always need to keep reminding ourselves, but when you get a situation like this, and it's showing again, you know, just being out there, chilling, telling stories, the odd joke.
"Rocco's caddie, he's caddied for the greats, so we were quizzing him as we were going around. So there was just plenty of conversation. And you end up shooting 64, and you go, oh, what, you know, you'd nearly forgotten about your score."
