"Nike is an iconic brand," Koepka says. "All these great, legendary athletes, such as Kobe Bryant, seem to be with Nike. I'm lucky enough to represent the best company in the world. I'm excited with what Nike will do in the future for the game of golf [and] I know that this partnership will help me achieve my personal goals."

Nike Golf has also signed of former Open Championship Silver Medal winner Tom Lewis.
Lewis, shot to fame in 2011 when he tied for the lead after the first round of The Open Championship at Royal St George's, shooting 65 in the process – the lowest score ever recorded by an amateur at the famous championship. He eventually finished T30, landing him The Silver Medal as leading amateur.
Three months later he won his first European Tour title at The Portugal Masters – it was just his third tournament start on the Tour.
'I've been working hard on my game during the off-season, and testing was a fun experience. I tried the Vapor Flex 440, Vapor Fly Pro and the Vapor Fly drivers, but I just felt the Fly gave me a more powerful ball flight, and enhanced all-round performance compared to the other two,' he said.
Lewis – who hails from Welwyn Garden City – competed in the victorious Walker Cup of 2011 prior to turning professional, as well as The Eisenhower Trophy and St Andrews Trophy the previous year.
He is one of three new European additions to the Nike roster for 2016, along with Sweden's Marcus Kinhult and Denmark's Lucas Bjerregaard.
