Stefanos Tsitsipas's first-round match against Shintaro Mochizuki at the Australian Open was briefly halted when a ball kid became unwell amid harsh conditions. The interruption occurred at the start of the third set, highlighting concerns over the tournament's demanding environment. Tsitsipas ultimately secured the victory after play resumed.
Stefanos Tsitsipas kicked off his Australian Open campaign with a win over Shintaro Mochizuki in their first-round encounter on January 20, 2026. This marked the second meeting between the players that season, following Tsitsipas's 6-3, 6-4 triumph at the United Cup just 18 days earlier. However, the match, played under intense summer heat in Melbourne, faced multiple disruptions.
The game lacked rhythm from the outset, with both competitors receiving medical treatment earlier, leading to a stop-start affair. Tension peaked at the beginning of the third set when Mochizuki was serving under pressure. He had opened the game with a 40-0 lead but was pulled back to deuce and faced another game point when play was suddenly suspended. A ball kid had vomited near the back of the court, prompting an immediate halt as medical staff intervened.
TNT Sports commentators in the UK expressed confusion during the broadcast. "We’re delayed here, we’ll stop and wait for it to get sorted. Goodness me, everything is going on. Something in the crowd, is it?" one remarked. Another referenced a prior technical issue at Rod Laver Arena during Naomi Osaka’s match against Antonia Ruzic.
Both players retreated to their benches while the situation was addressed. Play resumed after approximately eight minutes, but the pause proved detrimental to Mochizuki. Tsitsipas, the No. 31 seed and former finalist, broke serve immediately upon resumption to gain early control in the third set. He had lost the opening set to the world No. 112 but dominated the second, eventually sealing the match in the fourth set.
This incident joins a series of concerning episodes at the 2026 Australian Open. Just days prior, Ekaterina Alexandrova’s match against Zeynep Sonmez was paused when a ball girl collapsed near the umpire’s chair. Sonmez rushed to assist, and Alexandrova fetched ice bags. Play resumed after six minutes once the ball girl was stable. An earlier qualifying match between Moez Echargui and Luca Van Assche saw another ball kid collapse, quickly resolved with Echargui's help.
As the second round progresses in rising heat, questions mount about safeguards for players, ball kids, and staff at the Happy Slam.
