PACIFIC PALISADES, California — Little known American William McGirt, seeking his first PGA Tour win, broke clear of a congested leaderboard to seize a two-shot lead in Saturday's third round of the Northern Trust Open. Two strokes off the pace when the delayed second round was completed earlier in the day, the 34-year-old journeyman took advantage of several favorable pin positions with superb all-round golf to fire a six-under-par 65. McGirt birdied five of his first six holes, then picked up three more shots in the first four holes after the turn on the way to a 12-under total of 201 in the PGA Tour event at a firm and fast-running Riviera Country Club. George McNeill, a double winner on the US circuit, carded a 66 after eagling the par-five first to finish at 10 under, level with fellow American Charlie Beljan (68). Two more Americans, left-hander Brian Harman (68) and Monday qualifier Jason Allred (67), were a further stroke back in a tie for fourth. Eleven players were within four strokes of McGirt's lead, including former Masters champions Bubba Watson (64) and Charl Schwartzel (68), multiple PGA Tour winner Dustin Johnson (69) and 2013 PGA Tour rookie of the year Jordan Spieth (67). South Korea's Bae Sang-moon began the third round with a one-stroke advantage. — Reuters
