Dustin Johnson shot six-under par 66 on in the second round of the Farmers Insurance Open at Torrey Pines Golf Club in San Diego on Friday, ascending to third place, trailing only co-leaders Gary Woodland and K.J. Choi by a shot.
Johnson had a bogey-free round on the North Course to move up 32 spots in his quest to win for the first time in nearly a year.
Meanwhile, San Diego native Phil Mickelson, Rickie Fowler and defending champion Jason Day all missed the cut.
Mickelson, a three-time champion at Torrey Pines, shot a four-over par 76 on the easier North Course. Fowler, the winner of last week's Abu Dhabi HSBC Golf Championship, only shot an even par 72 on the South Course, while Day played the South Course in three-over par 75 while hampered by illness.
"It's mainly just physically, he has no energy," Col Swatton, Day's caddie, said. "Nobody wants to pull out of any event, especially one they are defending. He's really been working on his game, and it's disappointing to come here and not be able to use all that hard work to his advantage."
