DARIA Kasatkina caused the upset of the day by ousting 10th seed Belinda Bencic from Roland Garros in their second round clash. The Russian took no prisoners in a one-hour and 16-minute beating, running out a 6-2 6-2 winner over the talented Swiss player. Bencic was one of only two seeds to fall outside of a couple of walkovers, as Kasatkina served eight aces to one and hit seven more winners (27-20) and six less unforced errors (14-20) in a clinical display. Kasatkina also only dropped eight points off her first serve, and did not even face a break point, whilst breaking Bencic four times from nine chances.
“A lot has changed between 2018 and now,” Kasatkina said post-match. “There was one amazing year for me, which was important in a good and in the bad way. “I learned a lot, and I think I become a little bit different, maybe more experienced, a bit more serious. “Let’s say I understand more why I’m winning or why I’m losing.
“At that time everything was just going with the wave, and I was not thinking that much.” Now I’m analysing more what’s going on in the situation I’m in. “Getting maybe a bit more mature.”
Aside from the withdrawals of Naomi Osaka – which was announced after her first round win – and Petra Kvitova – which handed Romanian Ana Bogdan and Russian Elena Vesnina safe passage into the third round, 29th seed Veronika Kudermetova was the only other seeded talent to fall in the Round of 64. Kudermetova went down to Czech Katerina Siniakova, losing in three tight sets 7-6 5-7 7-5 in an epic two-hour and 52-minute match, the clear longest of the day. Kudermetova hit 18 more winners (45-27) but was far too inconsistent with 67 unforced errors to 43, as Siniakova was more efficient off her serve, and despite serving 10 double faults, made the most of her chances when they went in.
One of only two other matches that lasted beyond the two-hour mark was Sorana Cirstea‘s two-hour and 37-minute victory over Italian Martina Trevisan. Cirstea got up in three sets, 6-4 3-6 6-4 in what was a real arm-wrestle for the most part. The Romanian was far from her best, hitting 46 unforced errors to 28, and only had three more winners than her opponent (29-26), but won 50 per cent of her receiving points, and had higher success rates on her first and second serve. The Romanian won through to take on Kasatkina in the Round of 32.
The other epic was seventh seed Serena Williams needing to shake off a second set fight from another Romanian in Mihaela Buzarnescu to win in three sets in two hours and three minutes. Williams got up 6-3 5-7 6-1 to run away with the contest in the end, but not without some tough moments midway through the game. Williams hit one more winner (26-25) and had one less unforced error (27-28) in a relatively even contest, but it was her much higher first serve success rate (75 to 61 per cent) that proved the difference, as she broke five times to two and served the only five aces of the match.
A number of other contenders breezed through with 2019 Roland Garros runner-up Marketa Vondrousova showing no mercy to French wildcard Harmony Tan, winning 6-1 6-3 in 62 minutes on court. The quickest match of the day was 33rd seed Paula Badosa‘s 6-2 6-0 destruction of Montenegro’s Danka Kovinic in a lightning 52 minutes, while 21st seed Elena Rybakina defeated Nao Hibino 6-3 6-1 in 63 minutes. Danielle Collins breezed past Anhelina Kalinina 6-2 6-0 in 62 minutes, and Tamara Zidansek rolled into the third round with a 65-minute 6-4 6-1 trouncing of American Madison Brengle.
Elsewhere, Belarusian duo Aryna Sabalenka and Victoria Azarenka both advanced through to the the next round in two tight sets, with Madison Keys and Anastasia Pavlyuchenkova the other two seeds to make their way into the Round of 32. The only other match was Slovenia’s Polona Hercog taking care of France’s Carolina Garcia in straight sets, to complete the first 16 players through to the third round.
