Djokovic eyes semis after dismissing Zverev

"Found out two nights ago after I lost to Novak (Djokovic)", Isner, 33, told reporters after his 6-7 (2) 6-3 6-4 defeat - his second loss on his debut in the tournament.

From there Djokovic won the next three games, dropping only one point, as he wrapped up his second win of the week.

The top-ranked Djokovic and third-seeded Zverev engaged in a number of thrilling exchanges early on, but it wasn't until the ninth game that Zverev earned the first break point of the match, aided by a friendly net cord.

Zverev looked deflated and in spite of holding serve for 1-1 he offered no more resistance as Djokovic won five games in a row.

The World No.1 and favourite for a sixth London title was a comfortable 6-4, 6-3 victor over 6ft 10in Isner at the O2 Arena, London. His friend, Kyle Morgan, a former National Football League player who had worked the American player, died unexpectedly on Monday night, and Isner posted a moving tribute on Instagram that ended: "You were a friend, the best friend I could ever ask for". The younger Zverev outlasts Cilic, winning both sets in tiebreaks to take the match 7-6 (5), 7-6 (1). He will now face Djokovic on Friday, and Isner, with two defeats, will play against Zverev.

It seemed to knock the stuffing out of Zverev, who was broken in the fourth game of the second set, and again to love in the sixth.

"Personally I'm still not thinking of the number 100".

Djokovic also said fans should be patient with the likes of Zverev and fellow youngsters like Croatia's Borna Coric and Greece's Stefanos Tsitsipas as they seek to make their breakthroughs in the sport's biggest events. He has proven himself.

Tennis's world governing body the ITF was given the green light in August to launch a new Davis Cup format next year, culminating in an 18-nation finals week to be held at the end of November in Madrid.

This is when you start playing better tennis instead of thinking about all the bad things that are going on. "I didn't know it".

The evening session, of course, features two more over-30s in Cilic and Isner, but now the criteria had shifted a little with Djokovic's one-sided scoreline. Anderson was left stranded as he tried to change his body shape but get couldn't get time to react as the ball just went past him in the subtlest of fashion.

Cristiano Ronaldo was in attendance, with Djokovic perhaps spurred on even more by the Juventus forward's presence.
