Nicolas Colsaerts will have three shots to make up when Gary Woodland takes a one shot lead into the final round of the Farmers Insurance Open at Torrey Pines after difficult conditions saw much of the field struggle on day three.
With all players playing the tough South Course, Woodland fired a two under par 70 to move to eight under, a shot clear of Australian Marc Leishman and overnight-leader Jordan Spieth, who had to settle for a 75.
Woodland looked to be establishing a healthy lead before a shaky finish gave the rest of the field hope for the weekend.
The American hit birdies on the first, eighth, tenth and 14th to sit ten under before recording a first dropped shot of the day on 15.
The 29 year old regained that shot on 16 but a double-bogey on 17 saw him finish the day just a single shot clear of the pack.
Amongst those on five under were Belgian Colsaerts, who fell back after firing a 75, and Andres Romero whose 67 was the low round of the day.
The Argentinian hit six birdies and a bogey to fire himself into contention.
The group at four under included Keegan Bradley, Jason Day and Scotsman Russell Knox while Ian Poulter was a further shot back.
