Washington: A day after collapsing on the course, Jason Day produced a remarkable performance to claim a share of the lead heading into the final round of the 115th US Open at Chambers Bay.

Day was walking from the elevated tee on the par-three ninth — his final hole — on Friday when he suddenly fell to the ground, the 27-year-old needing several minutes of treatment before unsteadily getting to his feet and completing his round. The World No 10, who underwent a range of tests after withdrawing from a PGA Tour event due to severe dizziness three weeks ago, was later diagnosed as suffering from Benign Positional Vertigo and visibly struggled during Saturday's round.
