Walker leads at Pebble Beach National Pro-Am

American Jimmy Walker, seeking his third US PGA title in eight starts this season, fired a four-under par 67 Saturday to seize a six-stroke lead at the Pebble Beach National Pro-Am.

On a day when severe winds halted play for two hours and 20 minutes, play ended at sunset with 12 golfers being forced to finish their third round on Sunday morning.

According to Sports24, Walker sank five birdies against a lone bogey, his first of the event, at Monterey Peninsula to stand on 13-under 202 after 54 holes.

New Zealand's Tim Wilkinson, the only non-US player in the top 17, fired a 69 on the same layout to share second with Hunter Mahan on 208 at the 6.6 million dollar event played over three courses in the first three rounds before Sunday's finish at Pebble Beach.

Richard Lee was fourth on 209 while four-time Pebble Beach champion Phil Mickelson in a pack on 210.

On a day when severe winds halted play for two hours and 20 minutes, play ended at sunset with 12 golfers being forced to finish their third round on Sunday morning.

Winds gusted to 36 mph (58 kmh) on the seaside courses, with trouble starting at Pebble Beach when South African Trevor Immelman's ball was blown off line at the fourth hole.

Walker followed that with eight pars before back-to-back birdies at the 16th and 17th holes and a closing par to seize command on a day when scores soared, due in part to the blustery conditions.

Walker won the Frys.com Open last October and the Sony Open of Hawaii last month.
