Shapovalov upset in Dubai semifinals; Russia's Rublev makes anti-war plea

Canada's Denis Shapovalov fell to Czech qualifier Jiri Vesely in a wild semifinal that saw all three sets go to tiebreaks on Friday at the Dubai Tennis Championships.

Shapovalov was serving for the match up 5-4 in the third set before Vesely came back to complete a 6-7 (7), 7-6 (2), 7-6 (3) victory in three hours 12 minutes.

Vesely, who advanced to the semifinals with an upset of top seed Novak Djokovic, will face Russian star Andrey Rublev in Saturday's final.

Rublev defeated Poland's Hubert Hurkacz 3-6, 7-5, 7-6 (5) in the semifinals, then wrote "No War Please" on a TV camera moments after the match.

In the first matchup between the two players, Vesely often had the sixth-seeded Shapovalov on his heels.

Vesely fired 19 aces and had nine break point chances and converted two, the most crucial being the break in Game 10 of the third set Shapovalov was serving for the victory.

Shapovalov had seven aces and four break point chances. He converted two of those, including a break to put him up 5-4 in the third that he subsequently gave right back.

Vesely forced Shapovalov into three errors in the final tiebreak.

Compatriot Daniil Medvedev spoke Thursday at the Mexico Open about waking up to news that his country had invaded Ukraine.

"Watching the news from home, waking up here in Mexico, was not easy," said Medvedev, who will become the No. 1 men's
