Naomi Osaka claims she forgot to congratulate Victoria Mboko during her blunt loser’s speech at the Canadian Open. The Japanese star spoke for a mere 18 seconds after she suffered a disappointing defeat to the 18-year-old in the final.

Osaka has made progress since returning in last year's Australian Open. She won two matches in both the Australian Open and Wimbledon this year, has earned $725,727 in prize money and reached the No. 49 spot in the WTA rankings, with a higher ranking likely on the way by making the final.
