Wi three clear in California
South Korea's Charlie Wi holds a three-shot lead going into the final round of the Pebble Beach National Pro-Am in California.
The halfway leader, who is chasing his first PGA Tour title, carded a flawless three-under-par round of 69 at Spyglass Hill to move to 15-under-par for the tournament, three clear of American Ken Duke, who carded a superb 65 at Monterey Peninsula.
However, much of the talk of Saturday's play involved the form of former world number one Tiger Woods, who moved into contention four shots off the pace after shooting the day's best round at Pebble Beach, a 67, to move to 11-under-par.
Woods, who is making his first appearance at the event for 10 years, enjoyed a run of five birdies in six holes but was unable to maintain the momentum as he finished with seven straight pars.
Phil Mickelson is also primed to challenge on the final day as he will start in a share of fourth place at -9, alongside Kevin Na, Dustin Johnson, Hunter Mahan and Brendon Todd.
Padraig Harrington had been very much in the mix but two late bogeys saw him slip to eight-under-par in a share of ninth, alongside Bob Estes and Ricky Barnes, while England's Greg Owen is a shot further adrift.
