Eugenie Bouchard goes through in Luxembourg as Andrea Petkovic, owning a 5-2 lead in their head to heads, was forced to retire with a leg injury trailing 4-0 in the second set after winning the first 6-4. Qualifier Bouchard moved through to her second semifinal of the year at the BGL BNP Paribas Luxembourg Open, having scored five wins in a row for the first time since the 2014 season.
The Canadian, who has still yet to lose a match since hiring Michael Joyce on a trial basis, will face Julia Goerges. Goerges, the 2010 runner-up, reached her third semifinal in the tournament after moving to the last 4 in 2011, fired 32 winners and hit the seventh ace to convert the match point and complete a 6-3 3-6 6-3 victory against the No.6 seed Donna Vekic.
Dayana Yastremska hit 17 winners to complete the eighth straight victory as she outplayed 6-1 6-4 Tashkent champion Margarita Gasparyan. She stormed into the BGL BNP Paribas Luxembourg Open semifinals, where she will face Belinda Bencic.
The Swiss avenged the recent defeat in Linz as she beat Vera Lapko 6-4 6-1 to celebrate her maiden WTA semifinal since 2016 's-Hertogenbosch. Bencic and Yastremska met twice in the past 13 months, with the Swiss winning the ITF $100,000 final in St.
Petersburg and the teenager claiming her revenge at New Haven in the qualifying rounds. Yastremska has now won 16 of her last 17 sets as she won her maiden title in Hong Kong, clinched a marathon-victory over Varvara Lepchenko and stunned No.2 seed Garbiñe Muguruza to notch up her first ever career Top 20 victory.
Yastremska delivered a stunning pace to seal the eighth winner that gave her the chance to close the first set 6-1 in 23 minutes. The Ukrainian drilled a cool-headed forehand angle to seize the first break to move 3-1 in the second set.
Gasparyan, who started to serve more consistently, following a medical time-out broke back to 4-4. Yastremska maintained her feet on the pedal, winning the last 10 points to punctuate a massive performance. She tallied 17 winners to seal her place in her second straight semifinal.
Applying solid pressure from the start of most rallies, the Swiss comfortably dictated the game against a poor-serving, increasingly erratic Lapko. The Russian, who snapped a six-match losing streak this week, won 67% second serve points against the Belarusian, seeking to make her third career semifinal.
