The 28-year-old, who contributed one and a half points at Bethpage Black, carded a six-under-par 66 at the Old Course, St Andrews, to finish on 18-under-par in the weather-shortened tournament.

Tyrrell Hatton, another Ryder Cup standout, produced a superb seven-under final round to finish second, four shots behind MacIntyre.

MacIntyre followed in the footsteps of Colin Montgomerie, the last Scottish winner of the event in 2005, and claimed his fourth DP World Tour title.

He admitted that his preparation was far from ideal, arriving late in the week and playing only 12 practice holes. Despite an unstructured routine and a relaxed approach, the Scot produced three rounds of 66 at Kingsbarns, Carnoustie, and St Andrews to seal an impressive victory.

With Storm Amy forcing the cancellation of Saturday’s play, the event was reduced to 54 holes. MacIntyre began his final round with a birdie at the first hole and reached four-under by the turn. A single bogey on the 17th and a missed birdie opportunity on 18 were minor setbacks, but his lead was already secure.

Hatton’s charge came too late, while South Africa’s Richard Sterne, who started the final day in a share of the lead, and England’s John Parry both finished tied for third at 13-under.
