The second after his service game ended, Tsonga went storming over to the umpire. I think thre's somebody in the crowd thta's distracted him.

The umpire tells Tsonga thta he "has to stop" but Tsonga is genuinely furious. That outburst came out of nowhere.

Kyrgios then holds up play for a few seconds to fix his earring.

What a shot that is from Nick Kyrgios.

Two feet off the ground, a flick of the wrist, and the ball goes flying past Tsonga for 0-15.

Tsonga holds, though, courtesy of two big serves and a mis-timed backhand.

If Nick Kyrgios can keep this mentality and win this set then I think he wins in four. But there is still a way to go.

This feels more like the first set.

In no time at all, Kyrgios batters his way through his service game, once again holding to love.
