THE two grass event continued in Germany and England overnight, with the WTA 500 bett1open in Berlin and WTA 250 Viking Classic in Birmingham both seeing one big seeded upset apiece amongst relatively predictable results.
In Germany, a huge second round has been set with a couple of former world number ones in Victoria Azarenka and Angelique Kerber both claiming wins in the Round of 32. Whilst Azarenka was somewhat tested by Kerber’s compatriot Andrea Petkovic, Kerber had little to no issue disposing of Japanese left-hander Misaki Doi in one hour flat.
“It was a really solid match,” Kerber said. “It’s never easy to play a first match on grass courts, especially against a lefty as well. So I’m really happy about my performance and how I started the grass-court season.”
“It’s really nice being back on grass, that’s my favourite surface,” Kerber said. “It’s never easy to start a grass-court season because it’s completely different from the clay courts, but it’s great for me to play in Germany, it’s always really special. That gives me a little bit more motivation.”
Whilst Azarenka leads the duo’s head-to-head 9-1 and is seeded seventh here in Berlin, Kerber is on home soil and looking forward to the clash.
“I will try to play my game, and try to take another chance, and play as many matches as I can before I go to Wimbledon,” Kerber said. “It’s another good match at a high level, and this is why I’m here. The draw is really strong, so it’s good to have another good match.”
“I was sometimes dropping my level a bit with not being aggressive enough,” said Azarenka following her clash with Petkovic, which resulted in a 6-4 7-6(2) finish. “I was getting too frustrated in some moments when I had opportunities and didn’t take them, so I want to learn from that for my next round. I think I was putting myself into too much of a dangerous situation when I could have been more disciplined.”
Sixth seed Garbine Muguruza found success against Romanian Sorana Cirstea, 6-3 6-2, and whilst Muguruza and Cirstea hit a similar amount of winners (15-12), Cirstea registered a whopping 35 unforced errors throughout the one hour and 19-minute clash.
“Very pleased,” Muguruza said. “You never know how it’s going to go in the first match, especially on grass after two years, so I’m very excited to win in two sets against Sorana. We’ve played many times, and it’s always difficult.”
Things did not quite go to plan for eighth seed Czech Karolina Muchova, who fell to Russian Veronika Kudermetova in three, 7-6 5-7 6-2. Kudermetova said she drew on her third round loss at the Roland Garros to another Czech in Katerina Siniakova to get over the line in this encounter.
“I don’t know how to explain it but at the French Open I lost a very close match,” Kudermetova said. “I was 5-1 up, 5-2 up in both sets and I lost. Today I was a little bit thinking about it when I was up and serving. Mentally, it’s not really easy because I think and think about my serve. But I am really happy I stayed in the match in the third set.”
Another Russian-Czech matchup played out with the results going the way of the Russian once more with Liudmila Samsonova claiming the victory over Marketa Vondrousova and set to take on Kudermetova in the second round. Just one of four Americans claimed wins, as Jessica Pegula claimed a straightforward win over compatriot Hailey Baptiste who retired at the latter stage of the first set, while Roland Garros quarterfinalist Elena Rybakina and Croatian Petra Martic both took out wins over Shelby Rogers and Asia Muhammad, respectively.
At Birmingham, a huge upset was orchestrated by Australian hard-hitter Ajla Tomljanovic, disposing of top seed Belgian Elise Mertens in a marathon three hour and nine-minute clash, requiring three tiebreakers before the 7-6(5) 6-7(5) 7-6(4) result was decided. Fourth seed Daria Kasatkina overcame a slow start to steal victory off Polona Hercog, whilst second seed Ons Jabeur, fifth seed Jelena Ostapenko and sixth seed Zhang Shuai all dominated their respective contests to win in two. Meanwhile, Anastasia Potapova, Marta Kostyuk and Leylah Fernandez all found wins on their opening day of action.
