A dominant performance from second seed Alexander Zverev put the German into the last eight of the China Open in Beijing- beating Canadian youngster Felix Auger-Aliassime for the loss of just four games. Zverev remains on course for only the second title of a largely disappointing 2019, taking just an hour and two minutes to get past the world number 20 6-3, 6-1. Zverev now faces American Sam Querrey in the quarter-finals.
