AUSTIN, Texas -- The back spasms that nearly knocked Jason Day out of the WGC-Dell Match Play Championship have not been enough to keep him from reclaiming the No. 1 spot in the world.
Day will move atop the Official World Golf Ranking on Sunday regardless of how he fares on the final day at Austin Country Club after winning two matches to advance to Sunday's semifinals against Rory McIlroy.
Jordan Spieth's exit on Saturday morning set up the No. 1 scenario for Day, provided he defeated Brooks Koepka in his quarterfinal match.
