It's official: men's golf will have a new world No.1 from next week.
The man currently at the top of the pile, Brooks Koepka, could do no better than tie for 17th place in the Saudi International.
Consequently, no matter what happens this week, Rory McIlroy will leapfrog the American and take over the top spot when the rankings update again next Monday.
This will be the Northern Irishman's eighth spell as No.1 but his first since September 2015.
Should McIlroy spend more than three weeks at the top, he will overtake Sir Nick Faldo on the list of players with most weeks at number one. He's currently on 95 weeks in total, with Faldo on 97.

McIlroy overtaking Koepka comes just three-and-a-half months after the American played down talk of a rivalry between the two players.
"I've been out here for what, five years?” said Koepka. “Rory hasn't won a major since I've been on the PGA Tour. So I don't view it as a rivalry.”
"I'm not looking at anybody behind me. I'm number one in the world. I've got open road in front of me. I'm not looking in the rearview mirror."
