Having won the Shanghai Masters, Vacherot has now won 10 Masters 1000 matches in a row, enjoying a run of form that we usually only see from the world's best, not someone who had picked up just one win on the ATP Tour before it.
Auger-Aliassime, meanwhile, has won nine of his last 10 across all tournaments. As a result of that form, the Canadian still has a shot of qualifying for the ATP Finals, but only if he wins today.
12:50 CET - Rising star Victoria Mboko is through to the semi-finals in Hong Kong after her opponent Anna Kalinskaya was forced to retire with an injury, while trailing 6-1, 3-1.

09:35 CET - Dominika Salkova has progressed to the semi-finals in Jiujiang, with the Czech player proving too strong for Zhuoxuan Bai in a relatively routine 6-3, 6-4 victory.
07:58 CET - Some unfortunate news from Hong Kong this morning as top seed Belinda Bencic has withdrawn from her quarter-final clash against Cristina Bucsa due to injury.
The Spaniard advances to the last four, where she'll face either Maya Joint or Himeno Sakatsume.
Meanwhile, in Jiujiang, Viktorija Golubic and Lilli Tagger have moved into the semi-finals after straight-set victories over Yulia Putintseva and Tamara Korpatsch, respectively.
