Jannik Sinner earned his second straight-sets victory of the Australian Open fortnight on Wednesday, breezing past Tomas Martin Etcheverry 6-3, 6-2, 6-2 in John Cain Arena.

While some first-round matches have yet to be completed due to rain, the 21-year-old Italian took full advantage of his opportunity on one of three roofed courts at Melbourne Park where he raced into the third round in one hour, 44 minutes.
