French world No 50 Caroline Garcia sent US Open top seed Karolina Pliskova packing with a convincing 6-1, 7-6 (7-2) victory in the second round of the grand slam on Wednesday, while Naomi Osaka eased past Camila Giorgi in routine fashion. Garcia struck 30 winners against just 17 unforced errors as she delivered the biggest upset of the tournament so far. “I was ready for a good match. I knew I had to go for it and believe and be very aggressive, and that’s what I did very well,” said Garcia, who beat a top-20 player at a grand slam for just the second time in her career. Garcia enjoyed a sensational start, racing to a 5-0 advantage over the world number three. Pliskova finally got on the board in game six but Garcia took a commanding one-set lead in just over 30 minutes. Pliskova hit one single winner in the opening set and won just seven points on serve. A laser-focused Garcia kept up the pressure, and despite an attempted comeback from Pliskova, kept her cool in the tiebreak to set up a third round against American 28th seed Jennifer Brady. Later on Wednesday, Osaka reached the third round for the fifth time in five appearances at the US Open with a statement 6-1, 6-2 victory over Italian big-hitter Giorgi. The Japanese-Haitian star stepped onto the court wearing a mask emblazoned with the name of Elijah McClain, a young black man who died after police in Colorado restrained him using a chokehold and paramedics sedated him. I was playing well but I was feeling on the edge. What they are forcing us to go through is horrible. I want my freedom back. I feel like we are prisoners here Kristina Mladenovic Osaka had “Breonna Taylor” printed on her mask for her first match, and plans on honouring a different victim each time she takes to the court this tournament. “I just want people to sort of have more knowledge. I feel like the platform I have right now is something I used to take for granted and I feel like I should be using it for something,” the 2018 US Open champion said after her win. Dropping a mere five points on serve, Osaka was up a set on Giorgi inside 28 minutes and she started the second set just as strong, breaking her 74th-ranked opponent in the very first game. Osaka, who played with her left hamstring wrapped, doubled her advantage soon after and closed out the win on her third match point to set up a third round against 18-year-old Ukrainian Marta Kostyuk. Meanwhile, Novak Djokovic dropped his first tiebreak of the year but rebounded to overcome a stiff challenge from Kyle Edmund and make the third round. The world number one extended his undefeated run this season to 25-0 with a 6-7 (5-7), 6-3, 6-4, 6-2 win over the 25-year-old Briton. Djokovic will next take on German 28th seed Jan-Lennard Struff for a second time in as many weeks. Edmund took a marathon 82-minute first set on an ace that secured him the tiebreak. It was just the ninth set Djokovic has dropped this year and the first tiebreak he lost from 11 contested in 2020. The three-time champion responded well by taking the next three sets and wrapped up the victory in three hours and 13 minutes. Fifth seed Alexander Zverev punched his ticket to the third round for a third consecutive year at the US Open by sidestepping a tricky test from 19-year-old Californian Brandon Nakashima 7-5, 6-7 (8-10), 6-3, 6-1 in just under three hours. Zverev will meet French 32nd seed Adrian Mannarino in the last 32. Czech star Petra Kvitova, the sixth seed, recovered from an early deficit to move past Ukrainian world No 99 Kateryna Kozlova 7-6 (7-3), 6-2 and book a third-round match against in-form American Jessica Pegula. French world No 44 Kristina Mladenovic suffered a spectacular collapse in her second-round match against Varvara Gracheva. Mladenovic, who is one of the players confined to what they are describing as a “bubble in the bubble” after coming in close contact with Covid-19 patient Benoit Paire, led her Russian opponent 6-1, 5-1, and held four match points at 6-1, 5-2, but ended up losing the contest 1-6, 7-6 (7-2), 6-0. After her defeat, the Frenchwoman slammed the rigid restrictions she has been placed under since Paire’s positive coronavirus test.
