AVONDALE, La. (AP) — Ben Martin treated a tiny gallery to a course-record round, shooting a 10-under 62 on Thursday in the first round of the Zurich Classic.

Martin’s 10th birdie was his most spectacular shot in a round full of them as he chipped in from 55 feet on the par-3 17th hole. That came a hole after the 26-year-old former Clemson player he hit the flag on a chip from behind the green, setting up a tap-in par.

The previous record at TPC Louisiana was a 64, accomplished many times, including once earlier Thursday, when Andrew Svoboda did it to take a lead that held up until Martin surged past late in the day.

Peter Hanson and Sueng-Yul Noh were tied for third at 65.

China Open

SHENZHEN, China (AP) — Spain’s Alvaro Quiros and England’s Simon Dyson shared the China Open lead at 5-under 67 when play was suspended because of darkness at Genzon Golf Club.

Defending champion Brett Rumford was a stroke back along with Englishmen Tyrrell Hatton and David Horsey, Spain’s Adrian Otaegui, France’s Alexander Levy and South Korea’s Park Il-hwan. Levy and Park each had a hole left. England’s Ian Poulter had a 69.

Sweden’s Henrik Stenson opened with a 71. He was a chance to take the top spot in the world ranking from Tiger Woods with a victory.
