World number 10 Hubert Hurkacz is poised to donate €2,000 (£1,700/$2,100) to relief efforts in Ukraine after pledging to make a contribution for every ace he hits at Wimbledon - but his ace tally will not grow any bigger after he was knocked out in round one.

Hurkacz hit 20 aces in a five-set defeat versus Alejandro Davidovich Fokina today.

The Spaniard won Wimbledon's first 10-point final-set tiebreak 10-8 to seal a 7-6, 6-4, 5-7, 2-6, 7-6 victory.

Poland's Hurkacz had been in good form entering Wimbledon, winning the grass-court Halle Open earlier in the month, but was the first seed to be knocked out.

Still, the 20 aces he hit will see Hurkacz donate €2,000 to aid those impacted by the war in Ukraine.

Hurkacz announced before the third Grand Slam of the year that he would donate €100 (£86/$106) for every ace he hit at the event.

Players from Russia and Belarus are banned from Wimbledon this year because of the conflict in Ukraine.

Russia launched a full-scale invasion on February 24, with Belarusian support, and since then at least 4,731 civilians have been killed in Ukraine, according to the United Nations (UN).

The UN fears the true figure is far higher and it does not include fatalities from a Russian missile strike on a busy shopping centre in Kremenchuk today.

More than 7.5 million refugees have fled Ukraine.

Russia and Belarus have largely been frozen out of international sport because of the war, but tennis players from the nations have been able to play on the Association of Tennis Professionals (ATP) and Women's Tennis Association (WTA) Tours sans national flags.

The decision to ban Russian and Belarusian players outright from Wimbledon led to the ATP, WTA and International Tennis Federation stripping the tournament of its ranking points.
