Russian Medvedev has landed his second title in Dubai -- the first time he's ever won the same tournament twice -- and without dropping a set.
Griekspoor said after his straight-sets win over Andrey Rublev in his semi that he was struggling with a hamstring injury and would have retired had he lost the second set.
"Not how I want to win a final. Hoping the injury for Griekspoor is not too bad and wishing him a speedy recovery," Medvedev said on Saturday after the Dutchman's withdrawal.
The title is 30-year-old Medvedev's second of the 2026 season after he also won in Brisbane in January. At No. 11 in the ATP Live Rankings, Medvedev is just 45 points behind Alexander Bublik as he bids to return to the top-10 for the first time since June last year.
"That's what is crazy about it," Medvedev said when asked about winning the same event twice for the first time.
"I never did it in any city in the world, and the first time I do it, it's a walkover.
"We knew before the start of the week, the way I was practising, I couldn't miss a ball. We knew it was going to be a great week. It was a great week and I'm looking forward to the next tournaments to come."
It was Medvedev's 21st tour-level trophy on hard courts, tying him for second-most on the circuit among active players alongside Jannik Sinner and behind only Novak Djokovic, who has 72.
