Badosa, having stunned American third seed Coco Gauff in the quarter-finals, benefitted in the early stages as a tense Sabalenka conceded an immediate break of serve with four unforced errors.

Badosa was within a point of taking a 3-0 lead before Sabalenka switched up a gear.

The three-time major winner then took charge, reeling off four games in a row and was unrelenting from there.

Despite their off-court relationship, both players gave little away, barely exchanging a glance as they stayed focused on their respective tasks.

But, in a rare glimpse into their friendship, they shared relieved smiles after Badosa fell at the start of the second set before raising a reassuring thumb as she lay on the court.

What started as a fiercely-contested match began to drift away from Badosa when she gifted Sabalenka control of set two, conceding a break of serve with back-to-back double faults

Another double fault in the fifth game gave Sabalenka a chance for a second break, which she grabbed with one of her 32 winners before serving out victory in one hour and 26 minutes.

Sabalenka, who was later seen consoling Badosa in the players' area, said: "It was a super tough match against a friend, I'm super happy to see her at her highest level.

"After a couple of battles against each other we have spoken and decided to put it aside, and here we both wanted it badly."
