Naomi Osaka's second round victory at the 2026 Australian Open ended with a very uncomfortable handshake with her opponent, Sorana Cirstea. Following Osaka's three-set victory on Thursday, January 21, the two players met at the net before exchanging in a visibly tense conversation near the chair umpire. During the third set, Cirstea, 35, complained to the umpire about Osaka, 28, shouting "come on!" repeatedly during the match, including in between her serves. "Is this OK?" Cirstea asked.
