World number one Aryna Sabalenka edged a tight encounter against Olympic champion Zheng Qinwen to reach the French Open semi-finals.

Sabalenka, bidding for a first Paris title, won 7-6 (7-3) 6-3 against China’s Zheng on a blustery Court Phillippe Chatrier.

The Belarusian – arguably the favourite for the title – had to come back from a break down in the first set but showed all her fighting quality to advance.

“That was a true battle – I have no idea how I was able to get back into that first set,” Sabalenka said.

“I was ready to leave everything I have on court to win.”

Sabalenka has yet to drop a set at Roland Garros, with her improved serve and movement reaping rewards.

A potential mouth-watering meeting with three-time defending champion Iga Swiatek could await if the Pole beats Elina Svitolina in the second semi-final.
