As compatriot Georgia Hall, who had finished on eight-under-par, looked on, Law found the cup from 55 feet as both players carded third round 71s.

"That's why we play this game – for moments like that – and in front of a home crowd, it doesn't really get any better," 27-year-old Law told the Ladies European Tour's official website after clinching her second LET victory.

"Coming down the stretch and holing a putt like that to win, that's the epitome of the sport that we play and why we do it. Why we go through all the heartache, the pain and everything is for moments like that."

Australia's Whitney Hillier shot a final round 72 to finish at four-under and outright fifth. The 31-year-old from Geraldton in Western Australia carded previous rounds of 70 and 73 at the Centurion Club.

Law, meanwhile, took advantage of Hayley Davis' final round nightmare as the overnight leader shot a seven-over-par 80 to slip to a share of ninth place.

The winner's card included three birdies as well as the eagle, but also a dropped shot at the fourth and a double bogey seven at the 13th, and she knew exactly what she needed to do as she stood over her final putt.

"I had a good look at that leaderboard, waiting for it to scroll back up to the top so I could see what happened with Georgia. I kind of figured she'd made birdie on 18, but then it confirmed it," she said.

"I had a good read on the putt, but you never really say, 'Oh yeah, I knew that was going in'. I hit, saw it tracking towards the end and it went in – so a sigh of relief at that point."

Hall's round was less eventful as she picked up three shots while dropping only one, but Davis suffered throughout, making par on only seven holes alongside six bogeys and two doubles.

Sweden's Linn Grant (69) claimed third place on seven-under, the same score as another Englishwoman, Charley Hull, who finished a shot further behind in fourth.
