POTOMAC, Md. — Francesco Molinari delivered a record performance Sunday to win the Quicken Loans National.

Molinari holed a 50-foot eagle putt to start the back nine, then never stopped until turning the final round into a runaway. The Italian closed with an 8-under 62 for an eight-shot victory, matching the largest margin this year on the PGA Tour.

Molinari followed that eagle putt with an approach to 2 feet on No. 11, one of the hardest par 4s on tour that had yielded only one other birdie in the final round. He made three more birdies and ended his round by missing a birdie putt from 8 feet.

Tiger Woods closed with a 66, his lowest final round in more than five years, and was never close. Woods tied for fourth, his best result since a runner-up finish at the Valspar Championship three months ago, though he was 10 shots behind.

“I was only four back at the time when I made the turn, and so I thought that maybe if I got on the back nine, I shot 30 – maybe 29 – that would be enough,” Woods said. “Evidently I would have to shoot 24 on the back nine. What Francesco is doing back there is just awesome.”

LPGA: Sung Hyun Park beat So Yeon Ryu on the second hole of a playoff in the KPMG Women’s PGA Championship at Kildeer, Illinois, for her second major championship.

After a brief rain delay, Park finished off her South Korean compatriot with a 10-foot birdie putt on the par-4 16th hole.

Japanese teen Nasa Hataoko, after shooting an 8-under 64 to post a 10 under, dropped out of the playoff with a par on the par-4 18th. Ryu made a 20-footer for birdie from the fringe, and Park followed from 10 feet.

Park closed with a 3-under 69. She took a two-stroke lead on the 16th but hit left in the water on the par-3 17th en route to a double bogey. Park made a brilliant par save on No. 16.

CHAMPIONS: David Toms made one long putt to take the lead, then another to preserve it on his way to a one-shot victory at the U.S. Senior Open at Colorado Springs, Colorado.

Toms sank a 15-foot birdie on the par-3 16th hole to take the lead, then held on with a 20-foot downhill make after laying up from a fairway bunker on the 17th hole.

He saved par with a downhill knee-knocker from 3 feet on No. 18 to close out the round of par 70. Toms finished at 3-under 277 to edge Jerry Kelly, Miguel Angel Jimenez and Tim Petrovic.

EUROPEAN: Alex Noren of Sweden won the French Open by one shot at Paris after a 4-under 67 in the final round.

Noren started the day seven shots behind compatriot Marcus Kinhult but birdied two of his last three holes to finish at 7-under 277, just ahead of Russell Knox of Scotland, Chris Wood of England and Julian Suri of the United States.

Kinhult, who had a two-shot lead going into the final day, struggled in a round of 76 and finished tied for fifth.
