Former World No. 3 and 2016 finalist Stan Wawrinka returned to the quarter-finals of the St. Petersburg Open on Wednesday, beating Russian Karen Khachanov 7-6(10), 7-6(1).

The fourth-seeded home favourite served for the opening set at 6-5 but was broken to 15 when Wawrinka smashed a crosscourt backhand winner. The 33-year-old Swiss then had three set points from 6/3 in the tie-break, but Khachanov erased them all and later had two set points of his own.

At last, however, Wawrinka sealed the 22-point tie-break on his fifth set point. There was little drama in the second set, as Wawrinka clinched the tie-break and the second-round match on his first opportunity.

The Swiss wild card, No. 88 in the ATP Rankings, will next meet defending champion Damir Dzumhur of Bosnia and Herzegovina or Argentina’s Guido Pella.

Seventh seed Denis Shapovalov bided his time before upsetting the rhythm of Spanish qualifier Adrian Menendez-Maceiras 7-6(3), 6-2. The #NextGenATP Canadian won five of the first six points in the tie-break as well as five of the first six games in the second set on his debut at the ATP World Tour 250 tournament. Overall, he lost two of his first service points (31/33) and struck 10 aces in the 83-minute victory and now plays Italy’s Matteo Berrettini.

Elsewhere, fifth seed Roberto Bautista Agut, a semi-finalist in each of the past three years, was equally impressive on serve in beating qualifier Luca Vanni of Italy 7-5, 6-2 in 81 minutes. He awaits 2004 champion Mikhail Youzhny, who won his 499th match of his 20-season pro career on Wednesday. The Russian wild card beat Mirza Basic of Bosnia and Herzegovina 7-6(6), 6-4. Youzhny will retire after this week’s tournament.

Having won seven matches from qualifying to lift his maiden tour-level title at the Moselle Open in 2017, defending champion Peter Gojowczyk needed every ounce of his talent to notch another victory at the French event on Tuesday.

The German recovered from a set down, landing 17 aces, to overcome three-time champion Jo-Wilfried Tsonga, making his return from knee injury, 6-7(5), 6-3, 6-4 in one hour and 45 minutes. Competing for the first time since the Open Sud de France in February, Tsonga delighted the home fans with strong serving to take a one-set lead, before Gojowczyk battled his way back into the match to secure victory.

The 29-year-old, who reached his third tour-level final in Geneva four months ago, saved all three break points he faced and withstood an equal 17 aces from his opponent to book his spot in the second round. Gojowczyk’s route to a second title in Metz gets no easier, with top seed Kei Nishikori standing in the German’s way of a place in the last eight. This will be the first tour-level meeting between Gojowczyk and Nishikori.

Fifth seed Nikoloz Basilashvili notched his fifth victory in seven matches at the French event, defeating qualifier Kenny De Schepper 6-2, 7-6(0). The Hamburg titlist, who reached the semi-finals in Metz last year, dropped only eight points on serve throughout the 64-minute encounter, cruising to victory with a dominant second-set tie-break performance.

Basilashvili will, once again, face French opposition in the second round after #NextGenATP star Ugo Humbert rallied from a set down to beat Bernard Tomic 6-7(5), 6-3, 6-4. Humbert fired 17 aces and converted both break points he manufactured to progress after just over two hours.

German qualifier Matthias Bachinger set a second-round meeting with 2016 champion Lucas Pouille, following a 6-4, 6-4 win over #NextGenATP Spaniard Jaume Munar. Fellow qualifier Constant Lestienne also advanced, beating Jurgen Zopp 6-3, 7-5. Lestienne will face Richard Gasquet for a place in the quarter-finals.

Did You Know?
Seven of the past nine editions of the Moselle Open have been won by French players. Jo-Wilfried Tsonga (3), Gilles Simon (2), Lucas Pouille and Gael Monfils have all lifted the trophy in front of their home crowd since 2009.

Damir Dzumhur made a winning return to the St. Petersburg Open on Tuesday, recovering from a slow start to defeat Lucas Miedler of Austria 7-5, 6-3.

Having captured his first tour-level title at the event in 2017, the sixth seed struggled in the opening stages of his title defence. Dzumhur trailed Miedler by a double break in the first set, but rallied well to extend his unbeaten streak in the Russian city to six matches.

The defending champion converted five of nine break-point opportunities and won 70 per cent of first-serve points to advance after 84 minutes. St. Petersburg debutant Miedler was seeking his first ATP World Tour victory after straight-sets wins over Viktor Troicki and Uladzimir Ignatik in qualifying.

Dzumhur, who achieved a career-high No. 23 ATP Ranking on 2 July, will meet Ilya Ivashka or Guido Pella for a spot in the quarter-finals. The 26-year-old is yet to meet either potential opponent at tour-level.

Eighth-seeded Russian Daniil Medvedev needed only 67 minutes to defeat Joao Sousa 6-4, 6-1. The two-time tour-level titlist was clinical in important moments, converting each of his four break-point chances, to score his 30th match win in 49 tour-level contests this season. Medvedev will meet Mikhail Kukushkin or Denis Istomin in the second round.

Jan-Lennard Struff also enjoyed further success in St. Petersburg, beating #NextGenATP Russian Andrey Rublev 6-4, 7-6(6). The 2017 semi-finalist notched his fourth win in six matches at the event after 68 minutes, landing 18 aces in a strong serving performance.

Struff did not face a single break point throughout the first-round encounter, winning 88 per cent of points behind his first serve. The World No. 50 will face top seed Dominic Thiem in the second round.

Gstaad champion Matteo Berrettini took just under two hours to overcome 2013 finalist Guillermo Garcia-Lopez 7-6(5), 2-6, 6-3. The 22-year-old converted his only break point of the match in the decider to progress, improving to 17-15 at tour-level this season. The Italian awaits #NextGenATP Canadian Denis Shapovalov or Adrian Menendez-Maceiras in the second round.

Dominic Thiem and Karen Khachanov took a tour of St. Petersburg on Tuesday morning, cruising through the canals and out onto the Neva river to see the sights of the city.

“We had a really nice boat ride, in amazing company this morning,” said Thiem, who will play Andrey Rublev or Jan-Lennard Struff in the second round.

The Austrian also explained how he is ready to step up his bid for a third straight qualification at the Nitto ATP Finals, to be held at The O2 in London from 11-18 November.

“I have thought about the Race all year long,” said Thiem, who is currently in eighth position in the ATP Race To London. “Of course, I want to make it, as it’s the nicest tournament for players all year. I’d like to be in the Top 8.

“The US Open was great and I flew home with a great feeling, which I didn’t have the past two years. I am in good shape and I’m really looking forward to the tournament, the Asian swing, Vienna then the end of the season.

Meanwhile, Khachanov, who will face former World No. 3 Stan Wawrinka in the second round on Wednesday, is happy to be playing in his home country.

“It feels great to be back in St. Petersburg, my home in Russia,” said Khachanov. “It’s nice to play in front of home crowds, even if I do feel extra nerves and pressure. I try to deal with it as motivation. I’m really happy to be at a career-high No. 24 and it shows my hard work has paid off, I’m progressing. We’re focused on the work we have to do.”
