The pair traded breaks in the first two games but Federer made amends by grabbing a second one to restore his advantage and clinch the first set on his second set point.

The Swiss lured Khachanov to the net on several occasions, including at 4-4 in the second set and the Russian dumped a forehand volley into the net to give Federer two break points.

But instead of serving out the set, the top seed was broken again and the Russian even held two set points at 6-5 before the world number five recovered and forced a tiebreak. He converted his first match point to reach an 11th Halle final.
