"I had never played him".
Federer wrapped up the opening set after the first three games went against serve and there was a break apiece in the second before the legendary Swiss fended off a couple of set points to force a tie-break. In the victory, Khachanov won 71 percent of his first serve points and 40 percent of his second serve points.
The third seed needed to take a medical time-out to treat a back injury before playing on for a few points and retiring with the score at 3-2 in the first set for the Russian. In fairness, Zverev's margin of error is slim: If his serve doesn't hit his mark, right at the body, then he's just sent a softball right into Federer's strike zone, one he barely needs to move to crush.
Federer's compatriot Stan Wawrinka who reached the French Open final losing to Rafael Nadal participated at the Aegon Championships at the Queen's Club.
Federer has yet to drop a set in Halle this week.
"I thought I was very calm out there, even in hard moments".
The world number 12 booked his final spot after breaking at 3-3 and finishing the Frenchman off with another break to set up the showdown with Federer.
