Alexander Zverev has been tipped as a potential Grand Slam winner and lived up to his billing Tuesday by sweeping into the second round of the Australian Open in straight sets.

The 21-year-old world number four cruised past Aljaz Bedene 6-4, 6-1, 6-4 in 1hr 55min on Rod Laver Arena after coolly overcoming a minor first set blip when he lost his serve to the Slovenian world number 67.

The German next faces Jeremy Chardy or Ugo Humbert who face off later Tuesday in an all-French clash.
