Jelena Ostapenko and Marcelo Arevalo reached the Wimbledon 2026 mixed doubles semi-finals with a straight-sets win, but their victory was overshadowed by a heated argument after the match. The dispute drew attention away from the result and highlighted rising tensions on court during the tournament.

The flashpoint came when a late time violation penalty was issued, prompting Laura Siegemund to leave the court visibly upset. This sparked a confrontation between her partner, Edouard Roger-Vasselin, and Ostapenko, with accusations of persistent slow play at the centre of the row. The clash, captured on BBC coverage, added a bad-tempered edge to Ostapenko and Arevalo's progress through the draw.
