Charlie Wi fired a bogey-free three-under par 69 on Saturday to hold onto a slim lead but hard-charging Tiger Woods and Phil Mickelson climbed into contention at the Pebble Beach Pro-Am.
South Korea's Wi, chasing his first win on the PGA Tour, was at 15-under 199 with a three-shot lead after playing the more difficult Spyglass Hill course at the $6.4 million tournament.
Woods rediscovered his putting on Saturday to shoot a five-under 67 on Pebble Beach Links and was four strokes back of Wi at 11-under 203.
Meanwhile, Indian golfer Arjun Atwal's misery ended with yet another poor round of 76 in the third round. The score took his three-round total to 227 which meant he finished very close to the bottom of the leaderboard after missing his fifth cut in a row.
