New Zealand no.1 Danny Lee is on course for a top 20 finish at the AT&T Pebble Beach National Pro-Am in California today.
Nearing the end of his fourth round Lee sits in a share of 19th place at seven-under, seven shots behind leader Phil Mickelson.
Through 16 holes Lee, who led the tournament after the first round, was three-under for his round.
Lee's previous best finish on the PGA Tour is a tie for 66th at the Humana Challenge last month.
Former world number one Tiger Woods has fallen off the pace after dropping two shots through the front nine to sit five shots behind Mickelson.
