Roberto Bautista Agut stands in the way of Novak Djokovic

London: Four-time champion Novak Djokovic reached the Wimbledon semifinals for the ninth time on Wednesday, racking up his 70th career win at the All England Club in the process.

The top seed and world number one hit back from a break down in the first set to carve out a commanding 6-4, 6-0, 6-2 win over 21st seed David Goffin of Belgium.

In a ruthless display, the defending champion reeled off 15 of the last 17 games to secure a place in the semifinals of the majors for the 36th time.

Next up is Spanish 23rd seed Roberto Bautista Agut, who made his first Grand Slam semifinal with a 7-5, 6-4, 3-6, 6-3 over Argentina's Guido Pella.

"He started well and was dictating play from the baseline," 32-year-old Djokovic said of Goffin.

"Things could have gone a different way if I had lost the first set but I was very pleased with the second and third.

"I had a tough match in the third round (against Hubert Hurkacz). Other than that, I've won in straight sets and played really well throughout the tournament.

"It's exactly what I wanted and hopefully I can go in the right direction in the semis as well," he added.

Goffin was on top in the early stages as he sensed the opportunity to become the first Belgian man to make the semifinals at a Slam since Xavier Malisse at Wimbledon in 2002.

The 28-year-old broke for a 4-3 lead but 15-time Slam winner Djokovic then reeled off the next nine games, taking the first set, and the second in which he allowed the Belgian just four points on his serve.

The contest was over by the time Serbian Djokovic broke for a 3-1 lead in the third set.

Bautista Agut, 31, booked his first appearance in a Slam last-four at the 27th attempt by seeing off Pella, who had never previously reached a quarterfinal at the majors.

"Novak is the number one in the world and he's playing really well on grass," said Bautista Agut, who has a 3-7 record against the Serb.
