Emma Raducanu was bundled out of the Washington Open in a 6-4 6-3 semi-final defeat to Anna Kalinskaya. The British number one matched the Russian early, using her superior serve to pick up five aces. However, she was frequently unable to take full advantage of her firepower as she failed to convert any of her four break point opportunities.
