Li Na has made it through to the quarter-finals of the Rogers Cup in Montreal with a routine straight-sets victory over Sara Errani.
The 10th seed was dominant in the opening set and it took her just 37 minutes to win 6-4.
It got easier for the former French Open winner in the second as she saw off the Italian eighth seed 6-2.
Li will now take on either Chanelle Scheepers or Agnieszka Radwanska for a semi-final place.
