Jason Day collapses, proceeds to finish second round at U.S. Open

— -- UNIVERSITY PLACE, Wash. -- Australian Jason Day, in contention at the U.S. Open, fell to the ground while playing the ninth and final hole of his second round Friday, apparently due to vertigo symptoms he has been suffering with of late.

Day, ranked third in the world, at first appeared to slip, but television replays later showed he simply went to the ground as if he had fainted. Medical personnel attended to him for several minutes, and it took Day a good bit of time before he could get up.

His approach shot at the par-3 hole had gone into a greenside bunker and Day managed to play his shot onto the green. His playing partners,  Justin Rose and Jordan Spieth, let him putt first as it was clear Day was still not feeling well.

Day two-putted for a bogey to shoot even-par 70 and complete 36 holes at 138, 2 under par. He slowly made it to the side of the green afterward to seek more medical attention, then hopped a cart for a drive to the scorer's tent to sign his scorecard.
