Steven Bowditch has won the Byron Nelson Championship with a score of 18-under.
The Australian had led on all four days of the tournament, and four birdies on the back nine saw him finish four shots ahead of Charley Hoffmann, Jimmy Walker and Scott Pinckney.
Dallas-born Jordan Spieth fell down the leaderboard on the final day, finishing 11 shots off the pace.
It was Bowditch's second PGA Tour win.
