It was the Scotsman’s first victory in Asia and his winning total of nine-under-par 279 was just enough to give him a one-shot triumph over Japan’s Masahiro Kawamura at the US$1.75 million event, which was held at the DLF Golf and Country Club.

Starting the round with a three-shot deficit, the 44-year-old Gallacher stayed patient to overcome a roller-coaster round where he recovered from a horrible quadruple-bogey on hole 7 to take home a winner’s prize purse of US$291,660.

“I am 45 this year so I am really proud of what I did out here today,” Gallacher said.

“It changes my schedule and I can play a bit less and it was great to win with my son on the bag. He has caddied for me 20 events already, and to win with him there and on Mother's Day as well makes it even more special.”

Kawamura had the opportunity to force a play-off with Gallacher at the last but could not take it into extra time as he could only make par. The Japanese settled for second place on his own following a 73.

Local prospects Rashid Khan (70) and S. Chikkarangappa (74) finished as the highest-placed Indians in tied-10th position at the event which was celebrating its 55th edition this week.

Finland’s Kalle Samooja aced the 12th hole from 127 metres with his pitching wedge, marking the first time in the history of the Indian Open that three hole-in-ones were made in the same year.

Jake Higginbottom was the highest-finishing Australian. The New South Welshman shared 27th place after closing with four-under 68.
