Novak Djokovic produced another statement performance at the Miami Open on Thursday, coming from a break down in the second set to beat Sebastian Korda 6-3 7-6(4). But the biggest talking point from the match had nothing to do with the tennis.

The world No. 5 was spotted wearing giant gloves during the changeovers against Korda. A retired tennis star has now explained why Djokovic needed to use the oversized ‘ice’ mittens, which can be bought for under £25 online.

Djokovic has been known for using innovative, often unusual, methods to stay fit and energised on the court. The 37-year-old has previously made jokes about his “magic potions” of electrolyte drinks.

He’s also been spotted wearing “Iron Man” chest patches, which improve health and wellbeing. And Djokovic tried a new device during his match against Korda, donning giant blue gloves in between games.

The Newgo-branded ice pack gloves retail for around £23 and are “designed to provide cold therapy for your entire hands, finger and wrist”.

They are usually used as a form of pain relief, but Martina Navratilova has now explained why Djokovic needed them on a hot day in Miami.

“So they’ve had this technology years ago. They can lower your body temperature in like 30 seconds,” the 18-time Major winner said on Sky Sports.

“It cools down the blood supply and I don’t know why more people haven’t been using them.

“Novak is way ahead of everybody when it comes to technology. They didn’t have it in my day, but they have it now and I don’t really know why the tournaments don’t have it for all the players.”

It’s no surprise that Djokovic wanted to keep his body temperature under control on Thursday, as temperatures reached around 28 degrees Celsius in Miami, with plenty of humidity in the air.

The Serb is now through to the semi-final, where he will face fellow tour veteran Grigor Dimitrov. Djokovic has a 12-1 lifetime record against Dimitrov, with his only loss coming at the 2013 Madrid Open.

Djokovic has not made it this far in Miami since 2016, when he lifted the title. At the age of 37 years and 10 months, Djokovic also became the oldest semi-finalist in ATP Masters 1000 history, breaking Roger Federer’s record.

The Swiss star was 37 and seven months when he lifted the Miami Open title in 2019. And Djokovic will be hoping to follow in Federer’s footsteps by going all the way and lifting the trophy.
