LOS ANGELES (AFP) - Australian Jason Day is headed back to the top of the world golf rankings after a 3 and 2 quarter-final victory over Brooks Koepka at the WGC Match Play Championship in Texas.
By reaching Sunday's final four - where he'll face defending champion Rory McIlroy - Day is slated to supplant American Jordan Spieth, who was ousted in the round of 16 on Saturday morning at Austin Country Club.
Day, who first moved to number one after winning the BMW Championship last year, had put himself in position to ascend the summit again with his wire to wire victory in the Arnold Palmer Invitational last Sunday.
Day said that for him the return to the top is less about toppling Spieth or any other player and more about validating his own efforts.
"It's more so the journey and the process," he said. "To get to the top of your sport takes a lot of time and for me it's just really that delayed gratification I'm thankful for.
"I have been busting my butt and doing the right things and to be able to get back to number one in the world is fantastic."
