Mickelson leads Desert Classic by 2

Phil Mickelson birdied four of his last five holes Friday in the Desert Classic to take a two-stroke lead into the weekend in his first event of the year. A day after matching his career-low score with 12under 60 at La Quinta, Calif., Country Club, the 48-year-old Mickelson had a 68 on PGA West's Nicklaus Tournament Course to reach 16 under. The tournament winner in 2002 and 2004, Lefty will play the final two rounds on PGA West's Stadium Course.

Curtis Luck was second after a 66 on the Nicklaus layout. The 22-year-old Australian rebounded from a bogey on the par-3 eighth with a closing birdie on the par-4 ninth.

Adam Hadwin and Steve Marino were 13 under. Hadwin had a 66 at La Quinta, the course where he shot 59 two years ago. Marino had a hole-in-one in a 65, also at La Quinta.

Mickelson birdied the par-4 fifth and sixth holes, the par-5 seventh and closed with another on No. 9. On his opening nine, he birdied the par-5 11th and par-3 12th, then gave back the strokes with a double bogey after hitting into the water on the par-4 18th.

Henderson leads LPGA event: At Lake Buena Vista, Fla., Brooke Henderson of Canada played bogey free on her way to a 4-under 67 and a two-shot lead in the Diamond Resorts Tournament of Champions, the winners-only start to the LPGA Tour season.

Ariya Jutanugarn hit shots all over Tranquilo Golf Club at Four Seasons and was not sure how she managed a 67. But it left her two shots behind and tied for second with Lydia Ko (68) and Eun-Hee Ji (69). Jutanugarn is No. 1 in the world coming off a year in which the Thai swept every major award in women's golf.

Stacy Lewis, in her first event as a mother, followed her 68 with a 74. That dropped her to 17th place in the 26-player field of LPGA Tour winners the last two seasons.
