American teenager Coco Gauff booked her spot in the J&T Banka Ostrava Open main draw with a 6-4 6-4 win over former World No 22 Irina-Camelia Begu alongside Daria Kasatkina and hometown favourites Barbora Krejcikova and Tereza Martincova, who each pulled off upsets to advance as well.
Playing it safe wasn’t working! Coco Gauff
Gauff was imperious against the Romanian Begu, seeded No 11 in the qualifying draw, to advance after 90 minutes on Court 2.
The talented teenager, who initially enjoyed a bright start to the post-lockdown resumption, shocking No.2 seed Aryna Sabalenka in Lexington en route to the semi-finals, is coming off early defeats at the US Open and Roland Garros.
She will now take on another Czech wildcard Katerina Siniakova in the main draw.
In the most dramatic match of the day, former World No 10 Kasatkina came from 3-5 down in the final set against rising Czech star Marie Bouzkova to win through, 6-4 5-7 7-5.
Kasatkina was a game from victory in the second set before Bouzkova, the runner-up in Monterrey before the lockdown, reeled off 5 straight games and was twice 2 points from victory as she served for the match.
The Russian pulled off a brave last stand, winning 4 straight games of her own to turn the tide and march into the main draw, where she will take on No 6 seed Elena Rybakina.
Czech Krejcikova continued her upswing with a 6-3 6-2 victory over No 4 seed and Lexington runner-up Jil Teichmann.
A former Doubles World No 2, Krejcikova enjoyed her singles breakthrough at Roland Garros, reaching the second week of a major for the first time with wins over Barbora Strycova and Tsvetana Pironkova.
After a decisive win over Kaja Juvan to kick off her Ostrava qualifying campaign, the No 12 seed lost just 3 points behind her fist serve against Teichmann to ease into the main draw, where fellow qualifier Tereza Martincova awaits.
Earlier in the day, Martincova surprised No 7 seed Paula Badosa, 6-3 6-2.
Badosa earned back-to-back wins over Sloane Stephens and 2017 champion Jelena Ostapenko to reach the Round of 16 at the French Open, but struggled to find her range on serve as Martincova, who had No 8 seed Petra Martic on the ropes at the US Open, secured victory in under 80 minutes.

The inaugural edition of the J&T Banka Ostrava Open makes its debut on the WTA calendar with a draw featuring two Top 10 players, including home favourite Karolina Pliskova and Elina Svitolina, while Grand Slam champions Victoria Azarenka and wildcard Jelena Ostapenko also headline.
No 8 seed Anett Kontaveit is the highest seed in action on Day 1, and she starts her campaign in Ostrava against Ekaterina Alexandrova.
Kontaveit is playing her third hardcourt event since the season’s restart, having recorded a quarter-final run at the Western & Southern Open in New York and a round of 16 finish at the US Open, falling to Naomi Osaka in both tournaments.
Wildcard Kristyna Pliskova is looking to join her sister Karolina in the second round as she takes on Maria Sakkari, with the winner set to face top seed Elina Svitolina.
Pliskova came away victorious in the pair’s most recent clash at the Palermo Ladies Open, winning 6-4 6-4, but this will be their first meeting on hard courts.
Including the Pliskova sisters, the main draw features 5 players from the host nation of Czech Republic, along with Karolina Muchova, Katerina Siniakova and Barbora Strycova.
Two Czech qualifiers, Krejcikova and Martincova will face each other for the chance to play No 4 seed Azarenka.
US Open finalist Azarenka will be in action on Monday as she hits the doubles court with partner Muchova as they take on Ostapenko and Vera Zvonareva in the first round.
