The 33-year-old Mallinger had a 15-under 198 at CordeValle after opening with a 66 and matching the course record with a 62 on Friday. He has finished second twice in his seven-year career on the tour, losing in a playoff to Bo Van Pelt in Milwaukee in 2009.
Jonas Blixt was second after a 66, and Charles Howell III (66) and Jason Kokrak (67) were another shot back at 12 under.
Vijay Singh and Alexandre Rocha were 11 under. They each shot 66.
LPGA: Defending champion Na Yeon Choi of South Korea posted a 3-under 68 to maintain a two-shot lead after the rain-interrupted third round of the Sime Darby LPGA Malaysia.
Choi, who won the U.S. Women's Open in July for her first major title, birdied the first hole before rain halted play for more than four hours. She made three more birdies and was at 13-under 200.
Fellow South Korean Inbee Park (65) was two shots back after putting up the day's best score, while Karrie Webb was four shots back after a 68.

Funk won at The Woodlands in Texas in May for his seventh Champions Tour title.
