Last season Brooks Koepka bagged a pair of majors en route to the PGA Tour's Player of the Year award. He started the new wraparound season with an emphatic win at the CJ Cup to reach world No. 1 for the first time.

But amid the best form of his career, Koepka has a simple goal in mind as he gets ready to turn his attention to the new year.

"Stay healthy," Koepka told reporters. "That's been the big thing. I need to be healthy to be able to play all these events, play all the majors."

Koepka's breakthrough year comes despite the fact that he missed four months in the spring, including the Masters, while recovering from a wrist injury. He hit the ground running once he returned, with strong finishes at TPC Sawgrass and Colonial preceding wins at the U.S. Open and PGA Championship.

Now Koepka has added a third trophy after cruising to a four-shot win in South Korea on Sunday that allowed him to move past Dustin Johnson at world No. 1.

"I'm 1-for-1 this year, which is nice," Koepka joked about his undefeated record in the new wraparound season.

Koepka will be in the field next week in China for the WGC-HSBC Champions before putting the clubs on the shelf. With Justin Thomas paving the way by making the goal-setting process more public in recent years, Koepka explained that even after summiting the world rankings he plans to wait until 2019 to adjust his expectations for himself.

"I keep the same goals through the calendar year," Koepka said. "On Jan. 1 I go to the beach in the morning and go write down my goals and figure them out for the calendar year, but I just need to finish this year off. I've got next week and I would like to, coming out the first week as No. 1, I'd like to play well."
