Katie Boulter set up a showdown with world No 3 Coco Gauff after taking just over an hour to wrap up a straight-sets victory in her last-64 match at the National Bank Open in Montreal.
The British No 1 triumphed 6-3 6-1 in her opening match of the tournament against the host nation’s Rebecca Marino.
After taking the first set, Boulter continued to assert her dominance in the second by storming into a 3-0 lead and was able to close it out to reach the last 32.
