American tennis player Danielle Collins lashed out at unruly fans during her Round of 16 match at the Monterrey Open, expressing frustration at their interruptions. Despite temporarily silencing the hecklers, Collins lost to Erika Andreeva in three sets (1-6, 6-3, 6-3), marking Andreeva's first career win over a top-20 player. Collins, who was the top seed, showed visible frustration during the match, shouting, 'What in the world? It’s not that hard to let us play tennis and be supportive.' Collins' outburst and subsequent loss come as she plans to retire at the end of the season after a quarterfinal finish at the 2024 Paris Olympics. Andreeva, meanwhile, advanced to the quarterfinals of a top-level WTA tournament for the first time.
