WATCH: Canadians share touching moment of sportsmanship at US Open

It was a moment Canadian tennis fans were anxiously looking forward to, but in the end it was one the entire country can be proud of.

Up and coming tennis sensations, fellow Canadians and good friends, Denis Shapovalov and Felix Auger-Aliassime were facing off in the first round of the US Open Monday night.

After dropping the first set to the 19-year-old Shapovalov, 18-year-old Montreal native Auger-Aliassime took the second set 7-5. Both young men gave it their all as they went to the third set, unfortunately the match would end prematurely.

During the crossover, the stadium's medical staff tended to Auger-Aliassime after he said his heart was racing and was feeling faint. 

The Montrealer tried to go back out and continue, but did not look the same and ultimately retired from the match down 4-1 in the third set.

A visibly emotional Auger-Aliassime, who was making his Grand Slam main draw debut, hugged his good friend in the centre of the court. All Shapovalov could do was try to console the young man who he's known since he was eight. The exchange was an emotional and wholesome moment that was not lost on social media.

Many Canadians, some not even fans of tennis, admired Shapovalov's sportsmanship.

"It's really tough with the way it ended. Obviously I hope Felix recovers quick. I told him at the net that we're going to play a lot more times and we'll be back here playing in the finals one day," Shapovalov told TSN after the match.

The Ontario native will now face Andreas Seppi of Italy in second round action.
