was the defending champion, but withdrew before the tournament began.
Grigor Dimitrov won his first ATP World Tour Masters 1000 title, defeating Nick Kyrgios in the final, 6–3, 7–5, without losing a set throughout the tournament.
Rafael Nadal was the only member of the Big Four who played. His loss in the quarterfinals to Kyrgios ended a streak of 42 consecutive Masters 1000 events that at least one of the four reached the final. As a result of the withdrawals of both Andy Murray and Roger Federer due to injury, Nadal regained the ATP no. 1 singles ranking for the first time since July 2014.

Nadal became ATP no. 1 with only 7,645 points, the fewest points of an ATP no. 1 since the establishment of the new ranking points distribution in 2009.
