UNIVERSITY PLACE, Washington (Reuters) - Jason Day wrote his name into U.S. Open folklore on Saturday, grabbing a share of the third-round lead on a punishing Chambers Bay layout that had literally brought the Australian to his knees a day earlier.

Even though Day's round will be long remembered, there is still another chapter to be written in the 115th U.S. Open with Americans Jordan Spieth and Dustin Johnson and South African Branden Grace all level on four-under 206 going into Sunday.
