PHOENIX -- Karrie Webb tied the course record with a final-round 63 and came from six strokes behind to win the LPGA JTBC Founders Cup championship Sunday at the Wildfire Golf Club.
Webb birdied six of the final eight holes to overtake third-round leader Lydia Ko and finish with a 72-hole total of 19-under-par 269, one stroke ahead of a bunched group of five others, including Ko.
Webb won for the second time in the four-year history of the event, accomplishing the feat in the same way. She came from six strokes behind in the final round of the 2011 Founders Cup to pass Angela Stanford and win by one stroke.
Stacy Lewis birdied four of the final five holes to shoot a 6-under-par 66, finishing in a tie for second place with Ko, Azahara Munoz, Amy Yang and second-round Mirim Lee, who birdied No. 17 to get within a stroke of the lead.
Ko, Munoz and Yang were one stroke behind Webb with two holes to play but could not make up any more ground on the par-72, 6,583-yard desert course that yielded low scores all week.
Pornanong Phatlum, Jessica Korda and So Yeon Ryu were another stroke back at 271. Phatlum shot a 66.
Webb, 39, earned her 41st LPGA victory, her second of the season. She came from five strokes behind in the final round to win the ISPS Handa Women's Australian Open in February.
Webb, who finished 92 minutes before the final group, made a 20-foot putt on No. 18 to match the course record and take the lead. She was 12 under par over her final 22 holes after birdieing three of the final four holes Saturday. Webb played the last four holes in 9 under par for the week.
Ko, who took a one-stroke lead into Sunday, had a three-stroke lead after birdieing four of the first five holes, dropping to 20 under par. However, a bogey on No. 6 started a slide in which she bogeyed three of seven holes to drop to 17 under.
She blasted out of a greenside bunker to birdie the par-5 15th hole and get within one stroke of the lead. Ko pushed 12-foot birdie putts right on No. 16 and No. 17 and was just short on a 25-foot putt at No. 18.
Ko, who turned pro in October, was attempting to record her first LPGA victory as a professional after twice winning as an amateur, both at the CN Canadian Women's Open, in 2012 and 2013. She was the youngest winner in LPGA Tour history in 2012, at 15 years, 4 months and 2 days.
NOTES: Veteran Hee-Won Han also tied the course record with 9-under 63 Sunday when she birdied the final hole, leaving her 14 under for the tournament, tied for 15th. She had seven birdies and an eagle, holing out a 56-degree wedge from 95 yards on the par-4 seventh hole. She needed only 24 puts and shot a 6-under 30 on the front side. Han's last LPGA victory came in 2006. ... After rounds of 67, 66 and 67, Ko shot a 70 Sunday, going 2 over par over the final 13 holes. ... Michelle Wie, who was tied for fifth after three rounds, finished with a 70 and tied for 12th.
