Gutsy from Lehecka! As he tries to serve it out, Lehecka is faced with two break points. But he battles back and then produces the ace out wide to bring up his first set point.

Norrie goes long on the return and into a fifth we go!

Lehecka has really disrupted Norrie here, and the Briton is struggling with his second serve. Lehecka continues to attack Norrie’s uncertainty and the 21-year-old gets his reward with a double break.

He’ll serve for the set next.

Lehecka saves break point to hold his serve, finally consolidating his advantage. Norrie is under pressure now to stop this match going to a fifth.

Wow! Lehecka with the shot of the match to wrap up a third consecutive break of serve! Norrie opened the door with a double fault but Lehecka marches through with a forehand winner down the line! The match turns again!

Response from Norrie - and what a stunning forehand winner this is! This should deflate any momentum Lehecka wanted to create. Norrie first frustrated the Czech with an exchange at the net, and then whipped the forehand winner crosscourt on break point. Impressive.

Lehecka does it again! He broke Norrie in the opening game of the second set, and repeats the trick in the fourth! Brilliant return play from Lehecka, going after the serve, and he sends Norrie scrambling across the court. Then, Norrie can’t clear the net on the forehand, as Lehecka gets in front once more.

Norrie goes on the attack to start the fourth set and has an early look at 0-30, but the Czech responds with an ace and then a composed volley. Lehecka then puts away the forehand winner and follows it in well with a good play at the net. Nice save.

The errors are starting to fly off the Lehecka strings, two straight returns go long of the baseline - the first an aggressive return, the second a floating chip - and it brings up three set points for Norrie.

He takes it after Lehecka stetches for a forehand, another shot long, and Norrie wraps up the third set in just 29 minutes. Plenty of control on display there, from the British No 1.

Sixth seed Felix Auger-Aliassime moved into the fourth round with a battling 6-1 3-6 6-1 6-4 victory over Francisco Cerundolo.

Auger-Aliassime will play the winner of this match between Norrie and Lehecka.

Norrie has flipped this scoreline around quite impressively. Lehecka will serve to stay in the set, next.
