Naomi Osaka was on the brink of defeat at the Canadian Open, but she saved two match points to pull off an incredible comeback and win her first match with new coach Tomasz Wiktorowski

So far, the early results are promising for the budding partnership between Osaka and Wiktorowski. Osaka defeated Ariana Arseneault in the first round of the WTA 1000 Montreal yesterday. However, Osaka will face much stiffer competition in the 13-seed Liudmila Samsonova tomorrow. Currently, Osaka is the World No. 49 with a record of 22-11.

Osaka's time with Mouratologou followed an up-and-down sequence of promising signs and frustrations with either injury or close-run defeats.
