Gasquet's spirit appeared broken as Nishikori comfortably broke the 32-year-old's serve at the first time of asking, wrapping up the second set in just 33 minutes. I'm very happy with the way I played."There was plenty on the line for Anderson, who began the week in eighth in the ATP Race To London, as the South African is trying to qualify for the Nitto ATP Finals for the first time".

Gasquet won a crucial game late in the second set, breaking Anderson as he was serving to level the match to force a second tiebreak.
Milos Raonic was also beaten by Medvedev, the Thornhill, Ont., veteran falling in the quarter-finals.

The only surviving player in the draw yet to win an ATP singles title, Shapovalov is looking to break his duck at a tournament whose list of former winners includes Roger Federer, Pete Sampras, John McEnroe and Ken Rosewall. "I would have liked to win some of those matches in two sets, but I definitely have the mindset that whatever it takes, I'm going to keep going, keep focusing on what I'm doing, whether it's an hour, two hours, three hours, whatever it takes".
Shapovalov has yet to reach an ATP final in his young career, losing in three semi-finals this year.
