Fowler’s latest victory will propel the 27-year-old to fourth in the world rankings after topping a strong field that included US Masters champion Jordan Spieth and four-time major winner McIlroy.
Northern Ireland’s McIlroy (68) had been out of sorts, but three late birdies and then a 30-foot eagle on 18 gave him a 14-under aggregate of 274, with Fowler a stroke ahead and two holes to play.
The American (69) responded by birdying from off the green at 17, a rare smile flickering across his lips as he eventually ended on 272, 16 under.
Playing partner Pieters’ 25-foot eagle attempt at the last stopped three inches short, the Belgian’s 67 leaving him a stroke adrift on 273.
