(Reuters) - Brooks Koepka endured a frustrating day on the greens, shooting an even-par 70 that left him seven strokes behind first-round leader Keegan Bradley at the Canadian Open in Ontario on Thursday.

A week before going for a third straight U.S. Open title, there was nothing wrong with Koepka's long game, but he had trouble gauging the speed of the Hamilton Golf & Country Club greens, which he said were slower than he expected.
