Nike has partnered with world number one golfer Jason Day in a multi-year sponsorship deal worth a reported $10m a year.

Day broke the news of the long rumored deal on Instagram shortly before Nike released a promotional video of him wearing its apparel.

“Joining Nike is a dream come true,” Day said. “The brand is synonymous with the world’s best athletes. I’m honored and can’t wait to be part of the team and working closely with Nike to take my game, and the sport of golf, to even higher levels.”
