Defending champions Sabalenka, Sinner advance in rain-hit Cincinnati Open

World number one Aryna Sabalenka cruised into the Cincinnati Open quarter-finals with a 6-1 7-5 win over Jessica Bouzas Maneiro on Wednesday, while defending champion Jannik Sinner beat Adrian Mannarino following a lengthy rain delay.
