Jordan Spieth heaped praise on Curtis Luck after the young amateur managed to upstage him at the Australian Open.
Two-time major winner Spieth is the headline act at the Royal Sydney Golf Club as he returns from a long break this week, but Luck's 67 left the 20-year-old joint-top of the leaderboard.
Luck had conceded in the build-up to Thursday's round that he was nervous about playing alongside one of his idols, though Spieth claimed he was not immune himself.
He said: "I was [nervous] too, getting started. It's my first competitive round in six, seven weeks. [It's] Just first-tee jitters, but we had a lot of fun out there.
"It's a really, really impressive short game that Curtis has, he struck the ball nicely as well, but any time he got into trouble it felt like it [ended up being a] tap-in. That's something you certainly need to have to compete at a championship."
On his own round of 69, where the only blemish came with a bogey on the eighth, the American added: "I gave myself a lot of chances, but my putter was a bit cold.
"I think it just takes a bit of time to warm up, a couple of rounds to get into it. I just didn't adjust to the speed of the greens as well.
"I really felt like I gave myself a lot of opportunities, some easy birdies, which is nice.
"As the wind picks up and the week goes on you're certainly going to need to control the ball of the tee and putting becomes less of a factor, as long as you're hitting the greens in regulation."
