Alexander Zverev continued his strong form at ATP World Tour Masters 1000 events this season, beating Diego Schwartzman 6-4, 6-2 at the Rolex Paris Masters on Thursday.

A winner of three ATP World Tour trophies this season, Zverev has now reached the quarter-finals or better at seven of the nine Masters 1000 events in 2018. The 21-year-old German won 84 per cent of first-serve points (32/38) and saved all four break points he faced to move into the quarter-finals after 81 minutes. With a 54-17 tour-level record this year, Zverev is now just one match win away from equalling his personal best total of 55 victories achieved in 2017.

Schwartzman ends his season with a 33-25 record. Without dropping a set, the 26-year-old Argentine captured his first ATP World Tour 500 title in Rio de Janeiro earlier this year.

Zverev will meet Russia’s Karen Khachanov for a place in the semi-finals. Zverev leads Khachanov 2-0 in their FedEx ATP Head2Head series, which includes a five-set win at Roland Garros this year.

Karen Khachanov ended John Isner’s bid to qualify for the Nitto ATP Finals in dramatic fashion, saving two match points to beat the 33-year-old American 6-4, 6-7(9), 7-6(8). The World No. 18, who held three match points in the second-set tie-break, regrouped well in the decider, dropping just five service points (32/37) to advance after two hours and 28 minutes.

Khachanov now moves into his seventh tour-level quarter-final of the season and second at the ATP World Tour Masters 1000 level. Earlier this season, the 22-year-old reached the Rogers Cup semi-finals, falling in straight sets to eventual champion Rafael Nadal.

Isner was aiming to advance to the quarter-finals in Paris for the fourth straight year and maintain his hopes of making his debut at the Nitto ATP Finals in London. The 2016 runner-up ends his season with a 34-19 tour-level record. Isner lifted two tour-level crowns this season, winning the biggest title of his career at the Miami Open presented by Itaú and his fifth BB&T Atlanta Open trophy.

Dominic Thiem boosted his chances of qualifying for the Nitto ATP Finals on Wednesday, beating Gilles Simon 6-4, 6-2 at the Rolex Paris Masters.

The World No. 8, winner of three tour-level trophies this season, required just 84 minutes to return to the third round in Paris, winning 77 per cent of first-serve points. This week, Thiem is bidding to qualify for the Nitto ATP Finals for the third straight year. The 25-year-old currently occupies the eighth and final qualification spot for the elite eight-man event to be held at The O2 in London from 11-18 November.

“[Dominic] was patient and aggressive when he had windows of opportunity,” said Simon. “Every time [we reached 30-30], he made the right decisions. So I couldn’t play the match I wanted.”

With his seventh straight win over Simon, Thiem improves to 8-2 in his FedEx ATP Head2Head series against the 33-year-old Frenchman. The 11-time tour-level titlist will meet Rolex Shanghai Masters finalist Borna Coric for a place in the quarter-finals.

Competing at a career-high No. 13 in the ATP Rankings, Coric defeated Daniil Medvedev 6-4, 6-4 in 74 minutes. The 21-year-old, who will be appearing in the third round for the first time, improves to 4-1 in his FedEx ATP Head2Head series against the Tokyo titlist. 

Defending champion Jack Sock improved his unbeaten FedEx ATP Head2Head record against 2007 semi-finalist Richard Gasquet to four matches, beating the home favourite 6-3, 6-3. The 26-year-old American claimed his 10th victory in 13 matches at the event after 77 minutes, saving all four break points he faced en route to victory.

“I didn’t manage to get the upper hand in the match,” said Gasquet. “I didn’t manage to have the game that I wanted to have… I didn’t manage to push as much as I should have. I didn’t play well.”

The World No. 23, who is defending 80 per cent of his ATP Rankings points this week (1,400/1,760), will next face Malek Jaziri in the third round. Lucky loser Jaziri defeated Spaniard Fernando Verdasco 7-6(5), 1-6, 6-3 after two hours and 24 minutes.

Bryan/Sock Reach Paris Quarter-finals
Competing for just the second time since capturing their second Grand Slam title as a team at the US Open, Mike Bryan and Jack Sock made swift progress to reach the quarter-finals in Paris. The American team was forced to work hard on serve, saving 14 of 16 break points en route to a 6-4, 6-3 win over Divij Sharan and Artem Sitak. 

John Isner and Neal Skupski needed just 71 minutes to upset seventh seeds Henri Kontinen and John Peers 6-4, 7-5. The American-British duo saved each of the four break points it faced to book a quarter-final meeting with top seeds Oliver Marach and Mate Pavic or Rohan Bopanna and Edouard Roger-Vasselin. Bopanna and Roger-Vasselin beat Robin Haase and Matwe Middelkoop 7-6(3), 5-7, 10-5.

Marcel Granollers and Rajeev Ram also defeated seeded opposition, overcoming fifth seeds Jamie Murray and Bruno Soares 6-3, 6-3. The Spanish-American team dropped only one point behind its first serves (25/26) en route to a 63-minute triumph.

Swiss Indoors Basel titlists Dominic Inglot and Franko Skugor continued their strong run of form, defeating Ben McLachlan and Jan-Lennard Struff 6-3, 6-4. The British-Croatian tandem, which has lifted three tour-level trophies this year, will meet Pierre-Hugues Herbert and Nicolas Mahut for a place in the quarter-finals.

Aisam Ul-Haq Quereshi and Stefanos Tsitsipas set a second-round clash with Rolex Shanghai Masters champions Lukasz Kubot and Marcelo Melo, beating Gregoire Barrere and Adrian Mannarino 7-6(7), 6-4.
