Federer served out the match with an ace out wide, winning in one hour and 45 minutes.
The Swiss is two sets short of his all-time record streak, which he set between the third round in 2005 and the final in 2006.
"I wouldn't know that it happened in '05 and '06, I feel like these streaks just happen," he said.
"I'm equally happy if I would have won all the matches in four sets. That it happened to be in straights, it helps me for to save energy for the rest of the tournament."
