Wimbledon is well underway and the upsets are starting to come thick and fast, with French Open champion and womens fifth seed Mirra Andreeva the latest top seed to fall. The 19-year-old Andreeva, who lifted her first grand slam title just last month in Paris, lost to former Wimbledon champion Barbora Krejcikova, who found the form of her 2024 title run to win 4-6 7-5 6-4 on Centre Court. On the mens side, fourth seed and title contender Ben Shelton lost in a match tiebreak against Finnish qualifier Otto Virtanen on Tuesday in the biggest upset of the tournament so far, while former semi-finalist Elina Svitolina has also made a premature exit. Reigning champion and third seed Iga Swiatek survived an almighty scare in her first-round match against Taylor Townsend, while top seed Aryna Sabalenka now faces a tough third-round against Jelena Ostapenko. Reigning mens champion and top seed Jannik Sinner survived a scare of his own in the first round as he needed five sets to see off Serbias Miomir Kecmanovic, while seventh seed Novak Djokovic remains a possible semi-final opponent for the Italian.
