MELBOURNE (Reuters) - Novak Djokovic doled out a third straight lesson in outstanding hardcourt tennis as he waltzed into the fourth round of the Australian Open on Friday with a 6-3 6-3 7-5 win over Denis Istomin of Uzbekistan.
The Serb, trying to become the first man in the professional era to win the title in four consecutive years, looked in ominously good form as he took his place in the last 16 without dropping a set.
