Zheng Qinwen faced an unexpected defeat during the second round of the Australian Open, falling to Germany's Laura Siegemund in a match that marked one of the tournament's most significant shocks thus far. Zheng, the fifth seed and Olympic champion, expressed her dismay, admitting, "It was not my day," as she succumbed to a score of 7-6(3), 6-3 on the John Cain Arena. Despite the defeat, Siegemund acknowledged Zheng's talent, stating, "Zheng is an amazing player. One of the best players right now, but I know I can play well and I wanted to show that to myself" (Reuters).

The match highlighted Zheng's struggle to maintain concentration, particularly after failing to capitalize on several break point opportunities during the first set. Reflecting on the match, she commented, "I had a lot of chances to break her in the first set but at that moment maybe my concentration wasn't there" (SCMP).

Meanwhile, top seed Aryna Sabalenka successfully progressed to the next round after a challenging encounter against Jessica Bouzas Maneiro. Despite being pushed to the limits, Sabalenka maintained her composure and emerged victorious with a score of 6-3, 7-5. The Belarusian is on a quest to become the first woman to win three consecutive titles at Melbourne Park since Martina Hingis in the late 1990s. Reflecting on her match, Sabalenka noted the pressure she faced, stating, "She played incredible tennis today and it was a really tough one. I'm super happy with the win in straight sets." (Reuters)
