Some of the game's biggest names are heading home early at the Farmers Insurance Open. Gary Woodland and K.J. Choi share the 36-hole lead, and Dustin Johnson lurks just one shot off the pace, but defending champion Jason Day, last week's winner in Abu Dhabi Rickie Fowler and Torrey Pines veteran Phil Mickelson all missed the cut. Here's how things stand heading into the weekend in San Diego:
Leaderboard: Woodland (-9), Choi (-9), D. Johnson (-8), Martin Laird (-7), Scott Brown (-7)
What it means: Woodland followed up a 68 on the easier North Course with a 67 on the South on Friday to put himself in position for what would be his first PGA Tour win since the 2013 Reno-Tahoe Open after close calls last season at the CIMB Classic (T-2) and WGC-Match Play (finals loss to Rory McIlroy). The 46-year-old Choi, meanwhile, made five birdies on his second nine on the North Course to post a 67 of his own. Choi hasn't won on Tour since the 2011 Players, but did finish runner-up at this event to Scott Stallings. One shot back is Johnson, the No. 8 player in the world who has won in each of the last eight seasons, dating back to 2008.
Round of the day: Derek Fathauer fired a bogey-free 7-under 65 on the North Course, opening with three straight birdies on Nos. 1-3 and closing with three straight on Nos. 14-16 (the other circle on his clean card came at No. 7).
Best of the rest: Johnson, Chad Campbell and Jonas Blixt all turned in rounds of 6-under 66 on the North Course. Johnson and Campbell were bogey-free while Blixt made five birdies and traded a bogey against an eagle on back-to-back holes at 13 and 14.
Biggest disappointment: Playing through illness in his second start of the season, defending champion Day missed the 1-under cut after rounds of 72-74. Other notables heading home early include Justin Rose (E), Fowler (E), Hideki Matsuyama (E), Keegan Bradley (+1), Phil Mickelson (+1), Bill Haas (+2), Emiliano Grillo (+3) and Patrick Rodgers (+3).
Shot of the day: Despite missing the cut, Mickelson made two of the more unlikely birdies you'll ever see thanks to some creative work with his hybrid (he also punched out from under a fence in the parking lot).
