MELBOURNE (Reuters) - Russian qualifier Aslan Karatsev continued his fairytale run at the Australian Open on Sunday, reaching the quarter-finals on his Grand Slam debut with a 3-6 1-6 6-3 6-3 6-4 win over 20th seed Felix Auger-Aliassime.

Karatsev had not dropped a set in his previous three rounds, including a win over eighth seed Diego Schwartzman, but lost the first two against the Canadian on Sunday at Margaret Court Arena as he struggled with unforced errors.
