Dominic Thiem ended his Fernando Verdasco hoodoo to reach the quarter-finals of the Vienna Open in his homeland.

Top seed Thiem had lost all four matches against the experienced Spaniard before coming from behind to secure a 3-6 6-3 6-2 victory on Thursday.

The world number five will face Pablo Carreno Busta in his 11th last-eight encounter of another impressive season after recovering from a poor start.

Verdasco charged into a 3-0 lead and did not face a break point in the first set, but Thiem won 97 per cent of points on serve in the second as he forced a decider.

Thiem dominated the final set, Verdasco winning just one point on the Austrian's serve to bow out in the second round.

Andrey Rublev's hopes of winning back-to-back titles are still alive after the Russian beat Hyeon Chung 6-4 6-2.

Rublev, winner of the Kremlin Cup on home soil last weekend, will take on Matteo Berrettini, while fourth seed Gael Monfils defeated teenage wildcard Jannik Sinner 6-3 7-6 (10-8).

Diego Schwartzman accounted for Sam Querrey with a 6-7 (5-7) 6-4 7-6 (7-5) victory and Pablo Carreno Busta needed three sets to get past Mikhail Kukushkin, with Aljaz Bedene also advancing at the expense of Gilles Simon.

Novak Djokovic said a "flawless" straight-sets demolition of Lucas Pouille was one of his best performances of the year after coasting into the semi-finals of the Japan Open.

Djokovic took just 50 minutes to beat fifth seed Pouille for the third time this season, easing to a 6-1 6-2 victory on Friday.

The world number one crushed the Frenchman in the semi-finals of the Australian Open in January and it was an all-too-familiar story for Pouille in Tokyo.

Djokovic, eyeing a fourth title of the season after recovering from a shoulder injury which forced him to retire from the US Open, produced a masterclass of returning and served superbly to set up an encounter with David Goffin.

The top seed said: "It was definitely one of the best matches I've played this year. Best one of this week and came at the right time.

"I thought Lucas was playing really well the first couple of matches in this tournament. I took the time away from him."

Serbian Djokovic added on the ATP website: "I served well, served many aces, returned a lot of his serves back and just used every opportunity to come in. Just overall, a really flawless performance."

Goffin also made light work of reaching the last four, the Belgian not facing a break point as he brushed aside Hyeon Chung 6-2 6-2.

Australian qualifier John Millman moved into his first ATP 500 semi-final with a 6-4 6-0 defeat of Japan's Taro Daniel, and he will face American Reilly Opelka, a 6-3 6-3 winner over Yasutaka Uchiyama.

Hyeon Chung will face David Goffin in the quarter-finals of the Japan Open after denying Marin Cilic a milestone victory.

Cilic was expected to claim the 500th tour-level win of his career in Tokyo on Thursday, but Chung beat the sixth seed 6-4 3-6 6-1.

Chung, absent for much of this season due to a back injury, had not won a set in his previous three meetings with Cilic, yet the unseeded South Korean pulled off an upset to move into the last eight.

Cilic had a first-serve percentage of only 57 and double-faulted seven times to bow out of his first tournament since the US Open.

Chung said: "I'm just really happy because this is one of the best wins in my career so far. It was a really tough match against one of the best players in the world. I'm just trying to enjoy every point."

Goffin, winner of this tournament two years ago, got past Denis Shapovalov 7-6 (7-5) 7-6 (7-2).

There were no breaks of serve in a tight contest between the third seed and 20-year-old Shapovalov, but it was the Belgian who had the edge in the tie-breaks.

Qualifier John Millman went through with a 6-3 6-2 win over Lloyd Harris, while Taro Daniel defeated Jordan Thompson 6-4 7-6 (7-3).

Rafael Nadal cruised into the fourth round of the US Open with a routine 6-3 6-4 6-2 victory over Hyeon Chung at Flushing Meadows on Saturday.

Nadal was given the benefit of a walkover in the second round after the withdrawal of Thanasi Kokkinakis and, in truth, he was never really tested by Chung on Arthur Ashe.

The three-time champion was in complete control throughout, his win setting up a last-16 clash with Marin Cilic or John Isner.

Chung had come from two sets down to beat Nadal's compatriot Fernando Verdasco in the previous round, but there were never any signs of such heroics being repeated once Nadal forged ahead.

The South Korean qualifier produced only flashes of the brilliance that saw him reach the Australian Open semi-finals in 2018, and tougher tests are sure to await Nadal as he bids to regain the trophy he last won in 2017.

Nadal struck the opening blow in the sixth game of the match as Chung sent a cross-court backhand wide. 

Chung actually hit five aces to Nadal's four, but it was one off the Spaniard's racquet that wrapped up the first set.

A scintillating forehand down the line provided Nadal with what proved the decisive break in the second set and he did not have to wait long to make inroads in the third.

The third game of the set saw Chung drag a forehand off-target as he faded badly against the physical challenge presented by Nadal, the 23-year-old having only returned from injury at the end of July.

Asked about the potential benefit of a comfortable opening week in which he has only had to play two matches, Nadal told ESPN: "You never know, last year I had some tough matches and then in the semi-finals I had to retire [against Juan Martin Del Potro].

"You never know what's better. I have a tough opponent, John Isner or Marin Cilic [in the fourth round], I need to be ready for this, I can't think further than this."
