Day Nine at the Australian Open: Technology Disputes, Dramatic Wins, and On-Court Incidents

Day nine of the Australian Open featured various events, including disputes over wearable technology, significant match moments, and player conduct incidents.

Wearable Technology Restrictions Spark Controversy

A dispute arose regarding athlete wearable technology as Carlos Alcaraz and Aryna Sabalenka were not permitted to wear their preferred fitness tracking devices during their fourth-round matches. Manufacturer Whoop stated their devices are approved by the International Tennis Federation for in-match use and pose no safety or competitive risk, asserting athletes' right to monitor their performance data.

The restriction was reportedly due to the specific devices not being on an approved product list for the tournament.

Musetti Delivers Moment of Brilliance

Lorenzo Musetti demonstrated skillful play during his straight-sets victory against Taylor Fritz. A notable point involved Musetti executing a between-the-legs shot while retrieving a lob by Fritz, showcasing his agility and touch on court.

Australian Duo Triumphs in Thrilling Doubles

Australian players Kim Birrell and Talia Gibson secured a dramatic women's doubles second-round victory against Hanyu Guo and Kristina Mladenovic. After losing the first set 4-6, the Australians rallied to win the second set 6-4 following a prolonged period of play and an injury timeout taken by Guo. Birrell and Gibson then decisively won the third set 6-1, completing their comeback.

Code Violation for Darderi's Racquet Frustration

Italian player Luciano Darderi received a code violation during his match against Jannik Sinner. Following a service break in the second set, Darderi threw his racquet. He then continued to play a point with it before hitting a ball out of the arena. Darderi was subsequently penalized for ball abuse.

During a doubles match, Jelena Ostapenko hit Laura Siegemund in the face with a tennis ball. Siegemund temporarily fell but recovered from the incident. Ostapenko immediately apologized to Siegemund for the unintentional contact. Ostapenko and partner Hsieh Su-wei subsequently won their match against Siegemund and Sofia Kenin.
