Cameron Norrie shrugs off accusations of gamesmanship to reach fourth round

• Norrie keeps his cool in 7-5, 6-4, 6-1 win as Holger Rune rants
• British No 1 says: I stayed a lot calmer than he did throughout'

Until this year's Wimbledon, six short weeks ago, Cameron Norrie was still struggling to make his first appearance in the second week of a grand slam. Sometimes he faced brutal third-round encounters against Roger Federer and Rafael Nadal, while other times genuine opportunities passed him by.

These days, he makes it look easy. On Saturday afternoon, Norrie followed up his breakthrough in SW19 by calmly making his way into the fourth round of the US Open for the first time.
