Justin Rose successfully defended his title at the Turkish Airlines Open and reclaimed his spot at No. 1 in the World Golf Ranking. Rose survived the first hole of the playoff against Hao-Tong Li to pick up the win on Sunday.

“Obviously it’s nice to get there, and it’s nice to get back there. Maybe it’s actually even sweeter to get back there,” Rose said. “I was pretty aware of my playoff record, hasn’t been that great. So this was one I definitely wanted to win.”

With his Sunday victory, Rose moves back to No. 1 in the world, but it will very short lived. In just under 7 days Brooks Koepka will take over No. 1 in the rankings even though both players will not make a competitive swing.

Koepka’s divisor dropped from 45 to 44 in the two-year OWGR calendar, resulting in his average points rising. After this week, Koepka will have 10.32 average points to Rose’s 10.16. These calculations seem way harder than figuring out who will win the FedExCup. Maybe the rankings can be simplified like how next year’s FedExCup will be crowned.
