Choi mounts late challenge

KJ Choi earned a share of the final-day lead in the Farmers Insurance Open at Torrey Pines with a string of birdies.

The South Korean started the day well off the pace and looked unlikely to make much of a challenge as he dropped a shot on the opening hole.

However, he recovered from that poor start in superb fashion, picking up seven birdies in his next 13 holes to move to eight under for the tournament going into his final four holes.

That left him in a three-way share of the lead heading towards the closing stages, alongside overnight leader Gary Woodland and Jordan Spieth.

Woodland, who was one shot clear of second-round leader Spieth and Marc Leishman at the start of the day, was level par after five holes while Spieth was one under at the same stage.

Five players were one shot back on seven under - Russell Knox, Erik Compton, Graham DeLaet, Pat Perez and Marc Leishman.

Charley Hoffman had looked set to mount a title bid of his own after making a flying start to his round, including a hole-in-one at the par-three third.

He followed that up with birdies at the fifth, sixth and ninth, but he dropped a shot at the 10th and then four successive pars left him on six under.
