Djokovic stays world No 1 as Medvedev falls to Hurkacz at Miami

Daniil Medvedev said physical struggles destroyed any chance of a victory to reclaim the world number one ranking on Friday after falling to Poland's Hubert Hurkacz 7-6 (9/7), 6-3 at the Miami Open.

Medvedev dropped to second with a third-round loss to Gael Monfils at Indian Wells last week, but would have taken back the top spot from Serbia's Novak Djokovic had he defeated Hurkacz, the defending Miami Open champion.

Instead, 10th-ranked Hurkacz advanced to the semi-finals by ousting the reigning US Open champion at Hard Rock Stadium and 20-time Grand Slam champion Djokovic stays number one.

Hurkacz, now 2-2 all-time against the Russian, faces Carlos Alcaraz for a place in Sunday's final after the 18-year-old Spanish sensation produced a scintillating display to beat 48th-ranked Serbian Miomir Kecmanovic in three sets in one of the best matches of the tournament.

Medvedev said he found it hard to breathe at times and was cramping so badly in the locker room he was like "a fish on a sofa."

"All match, I wasn't feeling my best," Medvedev said. "After the tough points I was struggling to get my breath. I wasn't recovering fast enough. You just have to fight but in the second set I felt strange.

"I don't often feel like this but it happens sometimes when it's hot. Maybe it was the heat but I was feeling dizzy and tired and there was one game where I couldn't serve anymore. In the locker room I was cramping."

Medvedev called for medical trainers in the second set.

"The physio gave me something," he said. "You never know. You're hoping it will be like a magic thing but it doesn't always work like this."

'Cramp, cramp, cramp'

Hurkacz played well, taking full advantage of Medvedev's struggles, which lasted well after he walked off the
