Briton defeats Argentinian opponent in four tough sets

Novak Djokovic also takes four sets to beat Zach Svajda

Cameron Norrie continued his fine grand slam form by holding his nerve at the end of a bruising battle with Francisco Comesaña to win 7-6 (5), 6-3, 6-7 (0) 7-6 (4) and set up a third‑round match with Novak Djokovic.

Norrie, who reached the fourth round of the French Open and quarter-finals at Wimbledon this year, had looked well on his way to victory as he established a two-set lead. However, as he edged close to winning, his nerves increasingly came to the surface.

After establishing a 4-1 lead with a double break in the final set and then serving for the match at 5-4, Norrie found himself down set point at 5-6. As Comesaña lasered a backhand down the line, Norrie thought he had been forced to a fifth set and he began walking to his chair but the umpire confirmed the shot had landed out.
