Rickie Fowler, tied for the lead on Thursday, remained among the leaders after the second round of the Waste Management Phoenix Open, shooting a 3-under par 68.
Fowler, the winner of Abu Dhabi HSBC Golf Championship two weeks ago, is at 9-under par, one shot back of leader James Hahn. Danny Lee is also one stroke behind.
"I like playing in front of the big crowds and how crazy the fans can get, and being kind of acclimated to the atmosphere here definitely helps," Fowler said. "I grew up around action sports, and this kind of reminds me more of being at action sports event, and the fans being loud and having fun."
Hahn had the best round of the day, shooting a bogey-free 6-under 65 at the TPC Scottsdale. Harris English, Shane Lowry and Hideki Matsuyama, at 7-under par, also are in contention going into the weekend.
Phil Mickelson, a three-time winner of the event, shot an even-par 71 and is eight shots off the lead and tied for 37th.
Eight players have yet to complete their rounds because of darkness and will finish on Saturday morning. The projected cut line is set at even par' those on the bubble include Kevin Kisner, Justin Thomas and Jason Dufner, the latter a recent winner of the CareerBuilder Challenge.
