More US Open: Leaderboard | 10 Round 3 Thoughts | Sunday Storylines

Well, we've made it -- the final round of the 2015 US Open is finally upon us. And it's going to be quite the round on Sunday. Not only are four players tied for the lead at -4, but one of those golfers, Jason Day, moved up the leaderboard while battling vertigo.

On Sunday, Day will tee off alongside Dustin Johnson at 3:00 p.m. PT. Right in front of them will be the duo of Jordan Spieth and Branden Grace. Though those four players are the co-leaders, there will be plenty in pursuit. It all gets started at 7:55 a.m. PT.
