New Zealand golf No 1 Danny Lee was in a share of the lead after the first round of the AT & T Pebble Beach National Pro Am after his best score on the PGA Tour.
Lee, who has made the cut from one of four events in 2012, made five birdies and two eagles in his superb nine-under par 63. The highlight was a hole out from 106 yards on the par four 11th.
He shares the lead with South Korean Charlie Wi (playing at Monterey Peninsula Country Club) and American Dustin Johnson (Pebble Beach Links), a two-time winner of the event.
The course record at Pebble Beach is 62 held by American's Tom Kite in 1983 and matched by David Duval in 1997 when competitors were allowed to lift, clean and place their ball.
"I actually had some good breaks today," the 21-year-old Korean-born Kiwi said. "I made two eagles, I holed out from 100 yards away and one I think it was on the second hole, the par 5, I was in the bunker and the pin was in a very tough place to get up and down from actually. I hit the pin as it was the only way to stop the ball and it went in. After that I had some good momentum going and I think I played really nicely."
