Fire alarm delays US Open matches, halting electronic line-calling

On a Monday during the U.S. Open, play was interrupted for six minutes due to a fire alarm that led to the evacuation of the building housing the electronic line-calling system. This disruption affected not only Daniil Medvedev's match in Arthur Ashe Stadium but also all other matches taking place on different courts. The chair umpire announced the pause to the players and spectators, citing a technical difficulty with the line-calling system. At the time of the interruption, Medvedev was leading his match against Nuno Borges, having already won the first two sets and was ahead in the third set. The fire alarm incident caused a temporary halt in the tournament's operations, impacting a total of 15 matches in progress. The U.S. Tennis Association later confirmed that the alarm was a false alarm, allowing play to resume shortly after the situation was assessed. Medvedev ultimately completed his match with a decisive victory, winning 6-0, 6-1, 6-3. A similar situation unfolded at Louis Armstrong Stadium, where Beatriz Haddad Maia was serving for the first set against Caroline Wozniacki when the chair umpire informed the players and audience about the malfunction in the electronic line-calling system. This incident highlighted the reliance on technology in modern tennis and the potential for unexpected interruptions. Despite the brief delay, all matches were able to resume, and the tournament continued without further incident. The quick resolution of the alarm situation ensured that the players could return to the court and maintain the tournament's schedule.
