2017 Miami Open – Men's singles
Roger Federer defeated Rafael Nadal in the final, 6–3, 6–4 to win the men's singles tennis title at the 2017 Miami Open. It was Federer's third Miami Open title, 26th Masters 1000 singles title and 91st singles title overall. He saved two match points in the quarterfinals against Tomáš Berdych. This marked the third time Federer won the Sunshine Double, previously accomplishing the feat in 2005 and 2006. It was Nadal's fifth runner-up finish without winning the title. Novak Djokovic was the three-time defending champion, but withdrew before the  tournament began due to a right elbow injury. Reigning world No. 1 Andy Murray also withdrew before the start of the tournament due to a right elbow injury. This marked the first time since 1990, when the Masters Series/1000 tournaments were created, that neither the world No. 1 nor No. 2 played the Miami Open, and the first time since the 2005 Madrid Masters that neither Djokovic nor Murray featured in the main draw of a Masters Series/1000 event. Stan Wawrinka was the first player other than a member of the Big Four to be the top seed at a  Masters 1000 event since Andy Roddick at the 2005 Indian Wells Masters. Seeds.
