Jamie Donaldson upstaged Europe's Ryder Cup heroes with a stunning course record 62 on day one of the BMW Masters in Shanghai.
Equal nines of five-under 31 at Lake Malaren powered the Welshman to 10-under par and into a commanding four-shot lead.
All but one of Jose Maria Olazabal's winning team from Medinah are taking part in this week's co-sanctioned event in China and they're prominent in the chasing pack - as is the skipper himself.
Peter Hanson and Francesco Molinari - the man whose half point against Tiger Woods ensured outright victory for Europe - are Donaldson's nearest challengers after six-under 66s.
But the biggest threat is Rory McIlroy, who cruised round in five-under 67 to finish in tied fourth.
McIlroy, looking to extend his lead at the top of the Race To Dubai, closed with a short birdie on 18 to match the 67s of his Ryder Cup skipper Olazabal and fellow Northern Irishman Michael Hoey.
On a day of low scoring in the damp conditions, all 11 of the Ryder Cup stars on show carded 70 or better.
Martin Kaymer and Justin Rose are part of a six-way tie for seventh at four-under while Nicolas Colsarts, Paul Lawrie and Graeme McDowell are a further shot back.
Lee Westwood threatened to go low after getting to three-under after five but had to settle for a two-under 70 alongside fellow Englishmen and Ryder Cup colleagues Ian Poulter and Luke Donald.
Donaldson said later: "It was one of those rounds where you hit every shot where you want to and every putt where you want to.
"I played great from the word go, hit a lot of fairways and put myself in really strong positions and capitalised when I had putts. I didn't have many long putts, just played really well, and one of those days where everything went for me. It's been a really good day.
"The course suits me. The fairways are quite generous and if you miss the bunkers you can play aggressive golf.
"It's an awesome field, so I need to keep playing like that to stay ahead of them. The strength and depth across The European Tour nowadays seems to be very strong - it's just particularly strong this week."
Meanwhile, despite his impressive 67, McIlroy didn't feel he'd done anything special.
"It was okay," said the world number one. "I didn't feel I did anything spectacularly out there. I just played some solid golf.
"The targets on this golf course are big... big fairway, big greens so you're going to give yourself plenty of chances out there.
"It was a good, solid round of golf."
