22:24 CET - That was utterly imperious from the world number one, Jannik Sinner. The Italian was at his relentless, dismissive best as he annihilated a struggling Felix Auger-Aliassime 6-0, 6-2 in around an hour and 10 minutes to move into the Cincinnati semi-finals.
The Canadian won just nine points in the first set and didnt have a single game point, and his first winner came in the second game of the second set. As good as Sinner was, Auger-Aliassime didn't put up much of a fight.
But it is another scary performance from the defending champion. Can anyone stop him on the hard courts, where he is on a 25 match winning streak?
