Bill Haas pulled ahead with a 20-foot birdie putt on the par-4 16th and parred the final two holes for a one-stroke victory Sunday in the Humana Challenge at La Quinta, Calif.

Haas closed with a 5-under 67 for his sixth PGA Tour title and first since the 2013 AT&T National. He won the 2010 event for his first tour victory.

"Honestly, if you would have told me I would have done this last week, I would have laughed at you," Haas said. "To be here is an unbelievable feeling."

His father, Jay, won the 1998 tournament. Haas' great uncle, 85-year-old Bob Goalby, was in the gallery at PGA West's Arnold Palmer Private Course. Goalby won the 1968 Masters.

Haas was making his first start since November. He took the break to rest his left wrist, fractured in April when he fell down stairs.

"I played a little bit," Haas said. "I didn't just put the clubs up."

Part of a six-man tie for the lead after a par save on the par-3 15th, Haas got to 22 under with the birdie on 16. He two-putted for par from 20 feet on the par-5 18th after pulling off an awkward layup with his ball perched on top of the front lip of a right fairway bunker.

"I've been in a tournament where I've been maybe one ahead or tied, but not with five or six guys right behind me knowing that if I dump one in the water, I go from winning to finishing 10th," Haas said.

Matt Kuchar, Charley Hoffman, Brendan Steele, Steve Wheatcroft and Sung Joon Park tied for second.
