Scotland's David Law hit a career-defining hybrid shot for an eagle to win the ISPS HANDA Vic Open at 13th Beach today, while France's Celine Boutier held firm to take her first LPGA Tour victory.

David Law Celine BoutierLaw's eagle at the 72nd hole, with a brilliant three hybrid shot from 195 metres followed by a putt from just shy of three metres that rattled in the left edge, brought huge roars from the big crowd around the 18th green.

It took him from 16-under par to 18-under par and at the same time, overnight leader Wade Ormsby of Australia was self-destructing with a double bogey five from behind the green at the par-three 17th hole.

By the time Law signed for his 66 (with a back nine 31) and Ormsby imploded, the Australian needed an eagle at the last to force a playoff.

He hit his second shot to the fringe and from eight metres, his putt to extend an absorbing contest leaked low and right and Law was a first-time winner on the European Tour, having spent five years trying to earn his ticket playing away on the Challenge Tour.

The 27-year-old from Aberdeen admitted it was the greatest single shot of his career.

"It was the right shot to play at the time. Under that pressure and under that situation, needing to pull it off, it's something I'm so proud of."

Law at 18-under par won the men's section by a shot from Ormbsy and Brad Kennedy of Australia, who also had a share of the lead until he bogeyed the 17th today on his way to a 67.

In the women's section, Boutier only needed to card an even-par 72 having started two shots from the lead, owing to the fade-out of overnight leader Kim Kaufman of the USA.

Kaufman had an awful day; she double bogeyed the fifth hole from a tree behind the green and never recovered, shooting a 78 that left her tied-eighth.

Meanwhile Boutier, 25, from Paris, kept her nerve and then put the hammer down with a 10-metre birdie putt on the par-four 15th hole that gave her a two-shot lead that she would not surrender.

Previously she had logged only one top-10 in the LPGA although she was the world's No. 1 amateur a few years ago.

At one point Australian Sarah Kemp, who started out early and shot a 65 to post six-under overall, looked like she might have a chance. But Boutier's birdie at the 15th left her only needing to par in to win.

Kemp, fellow-Australian Su Oh and England's Charlotte Thomas finished tied-second at six-under par.
