Emma Raducanu was knocked out of the Cincinnati Open after a battling performance saw her slip to a narrow third-round defeat against world number one Aryna Sabalenka. Monday's match was the pair's second meeting of the year after Sabalenka edged to victory in their third-round encounter at Wimbledon.

Sabalenka's staggering tiebreak record illustrates her play under pressure but also her vulnerability in matches this year.
