Four-time grand slam champion Carlos Alcaraz made light work of Yoshihito Nishioka to continue his excellent start at the Australian Open.

Alcaraz wrapped up a 6-0 6-1 6-4 victory in just 81 minutes on Wednesday.

The Spaniard, who would become the youngest man to complete the career slam should he triumph at Melbourne Park, has now won both of his opening games of the season's first major in straight sets.

Alcaraz needed less than 20 minutes to seal a first-set bagel, and lost just one point on his serve in the opener.

And despite a resurgence from Nishioka in the final set, Alcaraz had little trouble in getting the job done with an excellent forehand winner down the line.

Asked about his rapid victory, the 21-year-old said: "The less time you spend on court in the grand slams, especially at the beginning, it's better.

"Physically, I'm feeling great, but I just tried to be focus and just spend as little time as I can [on court]."
