Rafa Cabrera-Bello shares the lead and Luke Donald had a hole-in-one on a good opening day for Europe at the Wyndham Championship.
Spaniard Cabrera-Bello and American Kevin Na fired matching rounds of seven under 63 at Sedgefield Country Club, making the most of good conditions for scoring to take a two-stroke lead.
More than half the field broke par on Thursday and neither Cabrera-Bello or Na had a dropped shot on their card.
Cabrera-Bello made four birdies on his front nine, having started at the 10th, and then eagled the fifth to move to six under before adding a further birdie at the ninth.
He finished fifth at the Olympic Games in Rio last week, and said: “It was the first time I was really not playing for myself, just playing for my country and obviously it’s a huge honour, but also big responsibility.
“I wanted to do good and I was pleased with my result. Coming into this week, I felt the game was good, I just needed a bit of rest.”
It was a similar story for Na, who started with a birdie at the first and made the turn in 31 before adding four more birdies on his back-nine.
Brandt Snedeker had a chance to join the leading duo but a wayward drive meant him dropping a shot at the last and having to settle for a 65, good enough for a tie for third.
The highlight of the day came from Donald, who is in Snedeker’s group on five under after the first 18 holes in Greensboro.
Donald was sitting on two under when he stood on the 16th tee, but he left the par-three four under thanks to a hole-in-one on the 175-yard hole.
America’s Derek Fathauer and Peter Malnati and New Zealand’s Danny Lee also opened with five under rounds.
Previous champion Patrick Reed is on four under in a group that includes Jim Furyk, fresh off his round of 58, Hideki Matsuyama and Bill Haas who was inches away from making an ace at the 12th.
But it was a bad Thursday for recently crowned PGA champion Jimmy Walker, whose bid opened with a four-over 74 that was derailed by a triple-bogey seven at the 14th.
