South Korea’s Charlie Wi shoot a bogey-free 6-under 66 to take the first round lead of the Zurich Classic by one-stroke in Avondale, Louisiana, USA.    

“To get off to a good start definitely puts you in a better position than coming from behind,” Wi said. “On the weekend, the golf course gets so difficult. So to shoot a good number on Thursday and Friday, I think it really helps you to have a high finish.”
