Rampant four-time Grand Slam winner Carlos Alcaraz dropped just five games in an ominous display of strength at the Australian Open on Wednesday to sprint into the third round. The Spanish third seed showed no mercy to Japan's Yoshihito Nishioka, who was taught a 6-0, 6-1, 6-4 lesson on Margaret Court Arena in an 81-minute rout. "The less time you spend on court in the Grand Slams, especially in the beginning, it is going to be better," said Alcaraz, who won Roland Garros and Wimbledon last year but is yet to go beyond the quarter-finals at Melbourne Park.
