Top seed David Goffin, who is currently No. 10 in the Emirates ATP Race To London and in contention for one of the three remaining spots at the Barclays ATP World Tour Finals, overcame a challenge from qualifier Marius Copil to prevail 5-7, 6-1, 6-3 in the quarter-finals of the European Open on Friday. Copil fought hard until the end, saving five match points before Goffin served out the match.

“He served some bombs,” Goffin said. “I really needed to find my footwork and my returns. I tried to make him go for some wrong shots, go for winners from tough positions.”

Goffin will play Diego Schwartzman, who beat fourth seed Pablo Cuevas, a winner of two ATP World Tour titles this year, 7-6(8), 6-3.

“It will be a tough match tomorrow. He’s a small guy like me, who likes to play on the baseline,” Goffin said of Schwartzman. “There will be a lot of rallies. It could be a very interesting match.”

Third seed Richard Gasquet remains on course to reach his third ATP World Tour final of the season after he beat Jan-Lennard Struff 6-2, 6-4 in 75 minutes. The Frenchman is trying to finish in the Top 20 of the Emirates ATP Rankings for a fifth time in six years (except 2014) and eighth time overall (2005-07). He will meet #NextGen star Kyle Edmund, who comes into the match on a high, having topped Andreas Seppi 6-3, 6-4 to reach his first ATP World Tour semi-final.

”It was a tough match for me against a good player, who won a Challenger a few weeks ago,” said Gasquet. “I knew how dangerous he was, having watched him win against Gilles [Simon] this week. I am very happy with the way I played, particularly in the second set, when he broke me at 4-2. It’s a good victory for me. It’s a great tournament and I hope to reach the final.”

Edmund, who is enjoying a career year, improved to 1-3 in quarter-final appearances at ATP World Tour events this year. He twice fell to Andy Murray (Queen’s, Beijing) and lost to Tomas Berdych in Doha.

Nestor/Roger-Vasselin Advance In Doubles

Daniel Nestor and Edouard Roger-Vasselin rebounded to beat Oliver Marach and Fabrice Martin 6-7(5), 6-4, 10-8 in the doubles semi-finals. It was a setback for Marach/Martin, who are 11^th in the Emirates ATP Doubles Race To London. They will lose grounds on No. 10 Juan Sebastian Cabal and Robert Farah, who are into the Moscow final.

Juan Martin del Potro withstood 12 aces from Ivo Karlovic on Friday at the If Stockholm Open to record his 26th match win of a comeback season, 6-3, 6-4 in 71 minutes. Del Potro moves on to face second seed Grigor Dimitrov. “I was expecting a tie-break in this match,” said del Potro. “But I’m happy to get the rest for tomorrow when I play Grigor.”

Del Potro leads Dimitrov 3-0 in their FedEx ATP Head2Head series, including a grass-court win at this year’s MercedesCup.

Dimitrov completed his fifth win in seven meetings against Kevin Anderson 7-6(3), 5-7, 6-2 in two hours and 18 minutes. “It’s never easy when you serve for the match and you lose it,” said Dimitrov, who lost four straight games after he served for the match at 5-3 in the second set. “There was some very poor serving form me today, that’s all I can say. I know Kevin was stepping in on pretty much everything, so the match could have gone either way.”

Fourth seed and #NextGen star Alexander Zverev beat qualifier Tobias Kamke 6-3, 7-6(5) in an all-German quarter-final to reach the final four. Kamke served for the second set at 5-4, but his countryman broke back and secured the win on his second match point. Zverev clinched his first ATP World Tour title earlier this month at the St. Petersburg Open (d. Wawrinka).

“It was a tough match, a good win,” said Zverev, a nominee for Most Improved Player of the Year. “Tobias played a very good match and if he keeps playing like this, he will surely return to the Top 100 again.

“The Swedish fans are great. They like to stay up late and come to support us. In Bastad I had a good run a year ago, so I can say that I play well in Sweden.”

The teenager will play an in-form Jack Sock, who faced only two break points in beating Gastao Elias 6-4, 6-4.

“Gastao beat Monfils the other day. He’s very consistent and makes you play a lot of shots. I was lucky to get through in straights,” Sock said. “The court has been playing pretty slow this week, which neutralises the power.”

Pavic/Venus Oust Top Seeds

Mate Pavic and Michael Venus beat top seeds Marcelo Melo and Bruno Soares 6-2, 6-4 to move into the doubles final. Soares and regular partner Jamie Murray have already qualified for the Barclays ATP World Tour Finals, while Pavic/Venus are No. 15 in the Emirates ATP Doubles Race To London and attempting to qualify for the year-end showdown for the first time.

Fabio Fognini got the better of Albert Ramos-Vinolas for the second time in as many weeks. The Italian extended his FedEx ATP Head2Head lead to 8-0 lifetime against the second seed with a 6-2, 6-2 victory on Friday for a place in the VTB Kremlin Cup semi-finals. Fognini, who also beat his Spanish opponent at last week’s Shanghai Rolex Masters, recorded his 25th match win of the year in 76 minutes. He will now challenge third seed Philipp Kohlschreiber, who beat Thomaz Bellucci 6-4, 6-2 in 76 minutes.

A duo of promising Russian teens enjoyed breakthrough runs in Moscow, but were felled by experienced opponents in the final eight. Daniil Medvedev took the second set 6-0 against veteran Stephane Robert, but lost 7-5, 0-6, 6-4 in his maiden ATP World Tour quarter-final. Nineteen-year-old Alexander Bublik pushed No. 6 Pablo Carreno Busta to a deciding tie-break, but succumbed 6-4, 2-6, 7-6(1). Robert and Carreno Busta will face each other for a place in the final.

Cabal/Farah Edge Russian Duo

Juan Sebastian Cabal and Robert Farah rallied to beat Konstantin Kravchuk and Andrey Kuznetsov 3-6, 6-2, 10-4 to reach the final. The No. 2 seeds are currently No. 10 in the Emirates ATP Doubles Race To London.

Jurgen Melzer joined Radek Stepanek as only the second active player to record 300 singles and doubles career match wins on Thursday at the VTB Kremlin Cup.

The Austrian partnered Julian Knowle to a 6-1, 5-7, 11-9 victory over Mikhail Kukushkin and Stephane Robert in Moscow. They will next face top seeds Pablo Carreno Busta and Marcel Granollers or wild cards Daniil Medvedev and Andrey Rublev in the semi-finals.

The 35-year-old Melzer has compiled a 347-331 record, including five titles as a singles player, and is now 300-242 lifetime, with 13 trophies, as a doubles competitor.
