Shanghai Masters third seed Holger Rune crashed out of the tournament in straight sets on Friday, becoming the second top-20 player to be knocked out that day.
World number five Rune never found his rhythm as he fell 6-0, 6-2 to 22-year-old American Brandon Nakashima, ranked 122nd in the world. Despite the crowd enthusiastically cheering the Dane on, Nakashima made short work of Rune, defeating him in an hour and nine minutes.
There was also an upset for Alex de Minaur, who fell 6-3, 7-5 to Hungarian Fabian Marozsan, who is ranked 91st to the Australian’s 11th. It was Marozsan’s second high-profile knock-out of the year — in May he inflicted a shock defeat on Carlos Alcaraz at the Italian Open.
Things went more to plan for a dominant Casper Ruud, who cruised through to the third round by easily dispatching Japan’s Yoshihito Nishioka 7-5, 6-0. Serbia’s Dusan Lajovic continued his progress through the tournament after opponent Tallon Griekspoor retired from the match due to illness.
