Novak Djokovic crashed out of the Abierto Mexicano Telcel in Acapulco following a quarter-final defeat to Nick Kyrgios.
The sixth-seeded Australian served brilliantly against the Serbian, sending down 25 aces on his way to the 7-6 (11/9) 7-5 victory over the 12-time grand slam champion.
He saved two set points to win the first-set tie-break, while taking advantage of the only chance he had to break the Djokovic serve in the second set.
It was the first meeting between the pair and 21-year-old Kyrgios, renowned for a volatile temperament that has seen him disciplined by umpires and tournament officials in the past, has now beaten Djokovic, Rafael Nadal and Roger Federer the first time he has faced them.
Kyrgios will play America’s Sam Querrey in the semi-finals after his 6-1 7-5 win over number four seed Dominic Thiem.
The American faltered when serving for the match at 5-3 and allowed the Austrian to rally and level the match, but Querrey broke straight back.
Nadal made it 13 career wins from 13 in Acapulco with a 7-6 (7/2) 6-3 win over qualifier Yoshihito Nishioka.
Nadal – who has won all 26 sets he has played at the tournament – raced into a 5-0 lead in the first-set tie-break and a forehand winner on the first set point wrapped it up.
Nishioka then broke Nadal early in the second set but Nadal responded to reel off four straight games and an overhead smash on match point wrapped up victory in one hour and 57 minutes.
Nadal will face Marin Cilic in the last four after Steve Johnson was forced to withdraw from their match with a sprained ankle.
