Emma Raducanu's Miami Open round of 16 clash against Amanda Anisimova was paused after a dominant first set due to the American suffering an injury. Raducanu looked a class above Anisimova as she stormed to a 6-1 win in the opener, dropping just nine points on the Butch Buchholz court.

After the Brit moved 5-1 ahead in just over 15 minutes, Sky Sports commentator Annabel Croft pointed out her opponent's defeated body language. Croft said: "She is all over the place. That sigh says it all. Fed up out here. Not enjoying this. She's being humiliated." Raducanu's momentum was then slightly disrupted in between sets, though, as Anisimova called the physio to her bench.

Anisimova received treatment on her right wrist, which was a known injury ahead of the match after she took a medical time-out for blisters in her victory against Mirra Andreeva on Sunday.

The situation against Raducanu later turned into a medical time-out as the physio took time to ease the discomfort in her right arm.

During the break in play, Croft added: "She was manipulating the wrist as well, which is actually quite painful.

"She's giving it a good working over, stretching out all those tendons and ligaments. I have to say I think she looked completely all over the place.

"She just had no clue how to play Raducanu in that first set, and she sort of almost lost interest in it, hadn't she?

"She was getting irritated, and also the way her body language was, she was rushing through service games like she wasn't ready or prepared to think about it or compose herself before the point. She is totally rattled emotionally."

Anisimova continued the match, but Raducanu wasted no time in breaking her serve again as she closed in on a ruthless win on the former's home soil.

Raducanu started her campaign by easing past Japan's Sakaya Ishii before an impressive second-round win against eighth seed Emma Navarro.

The 22-year-old beat another American in McCartney Kessler on Sunday, leading 6-1, 3-0 before an injury led to a walkover.

Anisimova, the 17th seed in Miami, beat Egypt's Mayar Sherif in straight sets before bettering Andreeva to set up her meeting with Raducanu.

She produced a battling display to continue after her medical time-out and had to call for the physio again in the second set.

But Raducanu ultimately triumphed 6-1, 6-3 to progress into the quarter-finals.
