British wildcard Katie Boulter delivered the biggest victory of her career, defeating world No 2 Elena Rybakina 7-5 2-6 7-5 to reach the HSBC Championships semi-finals at Queen's Club. The world No 73 battled through an epic three-set encounter against the top seed, showcasing her grass-court prowess on home soil.

Boulter's triumph came after already defeating Jaqueline Cristian 6-3 6-1 earlier in the day, with rain delays forcing her to play twice on Friday. Rybakina had survived a tough battle with defending champion Tatjana Maria earlier, winning 6-7 (4-7) 7-5 6-0 before falling to the British wildcard. Boulter now faces Croatia's Donna Vekic, who entered as a lucky loser after Marta Kostyuk's ankle injury withdrawal.

Emma Raducanu kept British hopes alive by defeating Sorana Cirstea 6-4 6-2 to reach the quarter-finals. Her match against Kamilla Rakhimova was postponed to Saturday due to scheduling delays, setting up a potential clash with Iva Jovic. The 18-year-old Jovic secured her semi-final berth by upsetting 2025 Wimbledon runner-up Amanda Anisimova 6-2 3-6 6-3.

Boulter credited the supportive crowd for driving her through the difficult moments, saying she simply kept backing herself and going for shots. This victory marks her second top-five win on the WTA Tour and represents a significant breakthrough in her career.
