In a disappointing start to their campaign at the Berlin Open, Serena Williams and Karolina Muchova were defeated in the opening round by the duo of Giuliana Olmos and Erin Routliffe. The match ended with a score of 6-4, 6-4, marking a challenging moment for Williams as it was her first match since returning to tennis this month. The loss comes just hours after Wimbledon confirmed Williams' participation, alongside her sister Venus, in the upcoming tournament. The Williams sisters have received wildcards to compete in the doubles event at Wimbledon, marking their return to the tournament after a decade.
