• Osaka rapidly defeats virus-hit Lesia Tsurenko 6-1, 6-1
• Nishikori beats Marin Cilic 2-6, 6-4, 7-6 (5), 4-6, 6-4 in marathon
In a rematch that far out-stripped their 2014 final Kei Nishikori exacted revenge on Marin Cilic during another energy-sapping afternoon to go through to the semi-finals of the US Open on Friday. He will be grateful for the two-day break.
Nishikori, so often bedevilled by injury, soaked up 19 aces from the Croat to win 2-6, 6-4, 7-6 (5), 4-6, 6-4, keeping a packed Arthur Ashe Stadium enthralled for just over four hours.
