Canada's Gabriel Diallo goes from wild card to champion at Granby National Bank Championship

Gabriel Diallo entered the Granby National Bank Championship to gain some experience for down the road.

It's safe to assume the 20-year-old Montreal athlete is a quick learner.

On Sunday, the six-foot-seven wild-card entry won his first title on the ATP Challenger Tour, upsetting the sixth-seeded Juncheng Shang in the tense final 7-5, 7-6(5) in Granby, Que.

In the championship final, Diallo played extremely well behind his serve — even though he failed to serve out the match up 6-5 in the second set. The Canadian kept 70 per cent of his first serves in play, winning 76 per cent of those points and delivering 10 aces. He also attacked Shang's second serve, winning 63 per cent of those points.

Diallo would only lose one point on serve in the second-set tiebreaker and managed to clinch the title with a mini-break on Shang's final serve.
