Australian Nick O'Hern leads by one-shot after shooting the only bogey-free opening round of the Reno-Tahoe Open in Nevada.
O'Hern carded seven birdies and 11 pars on his way to a 65.
He leads by one shot from American Chris Riley.
"Can't play much better than that," said O'Hern.
"Missed a couple of putts but every time I hit an ornery shot I got it up and down for par, so I kept the round going."
