China’s Zheng Qinwen has spoken about her struggle to find a usable pair of shoes for grass-court tennis after again changing footwear at the Queen’s Club Championships in London. Olympic champion Zheng changed her shoes during the sixth game of the deciding set of her semi-final defeat by Amanda Anisimova of the United States on Saturday.

Amanda Anisimova surprised Zheng Qinwen in the Queen's Club Championships semifinals with a 6-2, 4-6, 6-4 victory, setting up a clash for her first WTA 500 title this Sunday against Tatjana Maria.

However, during the latter match, the Chinese player been criticised for her conduct, with the Queen’s crowd not happy, groaning as Zheng continually halted play. She then saw fit to repeat that feat against Amanda Anisimova, without the same success.

China's Olympic champion Zheng Qinwen reached the semifinals on grass for the first time in her career as she knocked out home sensation Emma Raducanu 6-2, 6-4 at the Queen's Club Championships on Friday. Zheng, 22, entered the WTA 500 tournament as the top seed and received a bye in the first round.
