Brad Kennedy has raced home at the Japan Tour’s Dunlop Phoenix tournament with a brilliant final round to bolt up the leaderboard.

Kennedy signed for an impressive Sunday 66 to finish one place outside the top-10 at one of the Tour’s richest events.

American Brooks Koepka successfully defended the title he won last year with Kennedy the best of the five Australasians in the field.

Koepka dominated the field with a 20-under total for a nine-shot win, PGA TOUR rookie of the year Xander Schauffelle among the group of three to share second.

It was a somewhat erratic week for Kennedy who posted scores of 73-68-70-66 to reach 7-under for the tournament, three shots and 12 places ahead of Adam Bland on the leaderboard.

Bland was the last of the Australians to finish under par, Matt Griffin’s 1-over total good for a share of 47th.

Kurt Barnes was in position for a good finish through three rounds at 3-under and T22 but couldn’t get anything going Sunday and with a final round 77 slipped outside the top 50.

Brendan Jones was the only Australian to miss the cut, an uncharacteristic second round 78 doing the damage for the 14-time winner on the Tour.
