Australian Cameron Davis won the Rocket Mortgage Classic in Detroit as English golfer Aaron Rai’s challenge faltered in the final round.

Rai, looking for his first win on the PGA Tour, had a share of the lead with American Akshay Bhatia heading into the last day.

But the 29-year-old shot 72, including three bogeys in a six-hole stretch, as he finished a shot behind Davis.

Rai, a two-time winner on the DP Tour, finished tied for second after his even-par final round, but it represents his best result on the PGA Tour.

Davis was warming up for a potential play-off with Bhatia after he finished with an 18-under 270 at Detroit Golf Club’s North course.

However, Bhatia, in the last grouping with Rai, missed a four-foot putt on the final hole to hand Davis a second PGA Tour title.
