Andy Murray advanced to the second round at the European Open with a straight-sets win over Kimmer Coppejans.

The former world number one triumphed 6-4 7-6 (7-4) to win a match in two sets for just the second time since August.

He was made to work hard by Coppejans, who broke Murray three times in total, including in his first two service games in the second set, but the Briton eventually prevailed in an hour and 45 minutes.

Seventh seed Jan-Lennard Struff dropped just three games in beating Gregoire Barrere, while Gilles Simon and Feliciano Lopez were among the other players to advance.

At the Kremlin Cup, home hope Andrey Rublev overcame Alexander Bublik 6-1 3-6 6-4.

After taking the opener, Rublev then lost the first five games in a row en route to losing the second set and the sixth seed was a break down in the decider only to rally and progress.

Ivo Karlovic staved off a match point and won a third-set tie-break against Aljaz Bedene to progress, along with Jeremy Chardy and Philipp Kohlschreiber, who beat Nicolas Jarry and Pierre-Hugues Herbert respectively.

Pablo Carreno Busta was the only seed in action at the Stockholm Open and he defeated John Millman 6-4 6-3, with Sam Querrey among those to also go through.

Andy Murray reached his first ATP Tour singles quarter-final for a year at the expense of Cameron Norrie and will face Dominic Thiem in the China Open.

Murray consigned recent US Open semi-finalist Matteo Berrettini to a first-round defeat in Beijing and battled his way past fellow British player Norrie 7-6 (8-6) 6-7 (4-7) 6-1 on day three.

The former world number one needed eight minutes short of three hours to win through, securing back-to-back tour-level singles successes for the first time since undergoing hip resurfacing in January.

Murray, winner of this tournament three years ago, said he felt the effects of playing two matches in as many days and welcomed the opportunity to put his feet up ahead of a showdown on Friday with world number five Thiem.

"I'm tired, I just had a sleep before coming," said Murray. "I'm really tired. That's the first time I've had to do that since I came back... It's something that I need to kind of get used to again, especially playing at this level and that intensity.

"It was a good step for me. It's great that I won the match. Whether I'd won or lost it, I was able to come out the following day and be competitive and play some good tennis. But obviously I'm happy I've got the day off tomorrow to recover."

Thiem eased to a 6-3 6-3 victory over wildcard Zhizhen Zhang, who was unable to force a single break point.

Top seed Thiem, able to seal his place in the ATP Finals if he reaches the final this week, broke twice in the first set and once in the second to advance.

Fabio Fognini and Karen Khachanov also progressed with straight-sets victories over Andrey Rublev and Jeremy Chardy respectively.

Andy Murray bowed out in the Winston-Salem Open first round, while Lee Duck-hee made history on a rain-hit Monday.

Murray, playing his second singles match since undergoing hip resurfacing surgery in January, was edged by Tennys Sandgren 7-6 (10-8) 7-5 at the ATP 250 tournament.

The three-time grand slam champion, who accepted a wildcard into the event, had his chances before losing in two hours, 10 minutes.

Lee became the first deaf player to win a main-draw ATP Tour match, beating Henri Laaksonen 7-6 (7-4) 6-1.

The South Korean, 21, converted three of 11 break points in a historic victory.

Jeremy Chardy managed to get through to the second round courtesy of a 6-1 7-6 (7-5) victory over American qualifier Raymond Sarmiento.

Rain in North Carolina saw numerous matches postponed, with eight singles encounters completed.

Bjorn Fratangelo needed just 40 minutes to thrash Amir Weintraub 6-0 6-0 and Alexei Popyrin battled past Thiago Monteiro 5-7 6-4 7-6 (9-7).

Marco Cecchinato led Alexander Bublik 7-6 (7-3) 1-0 when the Kazakh retired, Pablo Andujar brushed past Nicolas Jarry 6-4 6-2 and Roberto Carballes Baena beat Marcos Giron 6-2 2-6 6-3.

Dominic Thiem had little trouble progressing into the quarter-finals of the Generali Open but second seed Dusan Lajovic bowed out on Wednesday.

With the top two seeds handed byes into the second round, French Open finalist Thiem made light work of wildcard Sebastian Ofner 6-3 6-2.

World number 26 Lajovic had no such luck against Jeremy Chardy, however, with the Frenchman coming out on top 3-6 6-4 6-3.

Chardy won 82 per cent of points behind his first serve and came from a break down in the third set to triumph.

Third seed Fernando Verdasco, who will face Lorenzo Sonego in the last eight, beat Jozef Kovalik 6-4 7-6 (9-7), while Pablo Cuevas surrendered the first set but rallied to overcome wildcard Dennis Novak.

Youngster Casper Ruud followed up an impressive performance against Pablo Carreno Busta on Tuesday with a straight-sets triumph over Matthias Bachinger.

Going up against Thiem in the quarters will be Pablo Andujar, who bettered Kitzbuhel resident and two-time champion Philipp Kohlschreiber 6-4 6-4.

Albert Ramos-Vinolas eased past compatriot Jaume Munar in Wednesday's other match.

Alexander Zverev stormed back to beat Filip Krajinovic and reach the German Tennis Championships semi-finals after splitting with coach Ivan Lendl, while Andrey Rublev claimed the scalp of Dominic Thiem.

Zverev and Lendl have parted ways less than a year after starting their collaboration ahead of the US Open.

The German could start the post-Lendl era with a second ATP Tour singles title of the season, having come from a set and a break down to beat Krajinovic 2-6 7-5 6-2 in his homeland on Friday.

Krajinovic served for the match at 5-3 up in the second set, but Zverev showed great resistance to pull himself off the ropes, winning four games in a row to level the match before largely dominating the decider.

Second seed Zverev will take on defending champion Nikoloz Basilashvili in the last four after the fourth seed beat Jeremy Chardy 6-2 6-3 in Hamburg.

Top seed Thiem's titles hopes were ended with a 7-6 (7-3) 7-6 (7-5) loss to 21-year-old Russian Rublev, who will face Pablo Carreno Busta - a 3-6 6-2 7-6 (7-4) conqueror of Fabio Fognini.

Carreno Busta's fellow Spaniard Roberto Bautista Agut was knocked out of the Swiss Open Gstaad by Joao Sousa, a 4-6 6-3 7-5 quarter-final winner.

Pablo Andujar and Albert Ramos Vinolas continue to fly the flag for Spain in Switzerland, though, and will meet at the semi-final stage following defeats of Dusan Lajovic and Roberto Carballes Baena respectively.
