Bradley closed with a two-under 68 – 15-under overall – to finish ahead of compatriots Fowler and Andrew Putnam, who shared second place on a see-sawing day of action.

Fowler came into the fourth round at the Narashino Country Club at 14-under for a one-shot advantage over Bradley and two strokes on Putnam, but he was unable to end a three-year PGA title drought at the Tour’s only event in Japan.

The trio all grabbed the lead at different stages on but Bradley went two clear with 20-foot birdie putt at the 11th hole before Putnam set up a potentially thrilling finish after catching up with him on the 16th.

But Bradley went two clear heading into the final hole with a clutch birdie on the difficult 17th as Putnam faltered and the 36-year-old held his nerve thereafter to claim the fifth tournament victory of his career.

Fowler’s hopes of claiming a sixth PGA Tour victory faded when he bogeyed the 15th before squandering the opportunity to claim a birdie in the next with another disappointing putt.

A late flourish on the 18th earned him a share of second place.
