Koepka was one of the company's most high-profile signings to begin the year, and he entered the week ranked No. 17 in the world. Hours after Nike decided to transition out of the golf equipment space, Koepka used his Nike equipment to shoot a 3-under 67 in the opening round at TPC River Highlands.
The score left him three shots off the early pace set by Vaughn Taylor and Andrew Loupe.
Koepka told reporters that he didn't learn of the Nike news until Wednesday, and his first thoughts went to the men and women whose lives will be most directly affected by the transition.
"I feel terrible for the guys that work for Nike Golf," Koepka said. "Mike Taylor and all the guys behind the scenes building wedges, putters, all these things, those guys are out of jobs. It's a sad day, and I feel terrible for them."
Koepka used Titleist equipment before transitioning to Nike at the beginning of the year, but his success after the change includes last week's T-4 finish at the PGA Championship. Koepka is now in prime position to qualify for his first-ever Ryder Cup team, and he indicated that he won't be switching to new equipment anytime soon.
"I love the golf ball and I love everything that I've got in the bag. There is no point in switching if it's working," Koepka said. "I don't see any changes coming in the next couple months."
