Kyrgios gets the mini-break as they trade groundstrokes in a rare long rally, with Khachanov miscuing an inside-in forehand as he tries to end the rally early. 0-1

Big wide serve and he crushes the forehand winner as Khachanov's return pops up. 2-0

Amazing 25-shot rally, with both players going toe to toe on the backhands, Kyrgios changing up paces nicely before ripping a winner down the line. Some moron shouted "OUT!" on one particularly close line call, but both did well to refocus. 3-0

Big serve gets Khachanov his first point. 1-3

But Kyrgios gets back into it, somehow turning defence into offence and forcing the error from Khachanov. 1-4

Kyrgios takes a 5-1 lead to the change of ends after serving and volleying on the second serve. Khachanov is standing so far back and couldn't come up with a passing shot. He may have to start stepping in on those second serves.

Ace brings up FIVE set points. 6-1

A Khachanov ace saves one. 2-6

A sensational rally, and Khachanov eventually forces the running forehand error from Kyrgios. God these guys hit the ball hard. 3-6

Three more set points. Two on serve for Kyrgios.

He only needs one. We're heading to a decider!
