Kei Nishikori eliminated Montreal's Felix Auger-Aliassime 6-1, 6-3 in the third round of the Barcelona Open on Thursday.

Since Auger-Aliassime and fellow Canadian Denis Shapovalov advanced to the semifinals of the Miami Open ATP Tour Masters 1000 hard-court event last month, the young players haven't had the same success.

Shapovalov has lost his last two matches, while Auger-Aliassime is 1-2 in the European clay-court season.
