Jamaican sprinting superstar Usain Bolt put his arm around Canadian upstart Andre De Grasse as the pair embraced the crowd at Rio's Olympic Stadium after the menā€™s 100 meter final on Sunday; a moment many are hailing as a passing of the torch to the next generation of Olympic sprinting.

While Boltā€™s exodus from competition is still a matter speculation, De Grasseā€™s first track coach believes the 21-year-old Markham, Ont.-native will become a leading force in the marquee event as he evolves as an athlete.

ā€œAs Andre continues to mature physically and gets a little stronger, he will definitely get faster,ā€ former coach Tony Sharpe told Ā鶹“«Ć½ Channel. ā€œThere are lots of big things ahead for Andre in terms of lowering his times.ā€

Sharpe discovered De Grasse at a Southern Ontario high school track meet. De Grasse was supposed to watch a friend from the sidelines that day, but couldnā€™t deny his competitive side. He placed second wearing borrowed cleats and basketball shorts.

ā€œI said, ā€˜Who is that?ā€™ Typically you donā€™t see walk-ons that compete that well,ā€ said Sharpe, himself a former 100- and 200-metre Canadian champion and Olympic teammate of Ben Johnson.

De Grasse was initially reluctant to embrace sprinting, but Sharpe convinced the high school student of his potential.

ā€œI got introduced to him later on and told him I could help him. He joined the club and the rest is kind of history,ā€ he said.

De Grasse won the bronze medal for Canada in Sundayā€™s menā€™s 100 meter final. Bolt overpowered second-place American Justin Gatlin, winning his third straight Olympic gold in the event.

Sharpe says De Grasse went into the race believing he would win. De Grasseā€™s qualifying time was four one-hundredths of a second quicker than Bolt - the reigning fastest man in the world.

ā€œYouā€™re not running for second, youā€™re not running for third, youā€™re running to win the hundred meters,ā€ he said. ā€œI thought Andrew could win.ā€

Sharpe says De Grasse is a mentally tough athlete known for keeping calm and performing well in competition.

ā€œI donā€™t remember Andre going to any major competition where he didnā€™t do well, like had a bad day. It just doesnā€™t seem to happen,ā€ he said.

Sharpeā€™s biggest concern was De Grasse getting a good start to the race, since heā€™s not known for being fast off the blocks. He delivered an impressive 9.91 second personal-best time.

ā€œA lot of athletes might perform well, but itā€™s more important to perform at the right time ā€¦ thatā€™s the kind of character he is.ā€

Remuro Henry, De Grasseā€™s coach at Wayland Baptist University in Plainview, Texas, also hailed the young sprinterā€™s performance in a chat with Ā鶹“«Ć½ Channel.

ā€œIt was just amazing,ā€ Henry said of De Grasseā€™s bronze medal finish on Sunday. ā€œYou know, I Just broke down in tearsā€¦ I was sweating more than he was. I was going to pull my hair out!ā€

Henry says that when he first met De Grasse, the Canadian runner was far from being the dedicated athlete that he is today.

ā€œHe was just a laid back guy,ā€ Henry reminisced. ā€œHe didnā€™t really know how talented he was -- and he really didnā€™t care too much for it.ā€

That blasé attitude was gone on Sunday, Henry said. In its place was confidence, bravery and toughness.

ā€œI told everybody heā€™s going to get better as he goes,ā€ Henry boasted. ā€œOnce heā€™s up and running, other than Bolt, I donā€™t think anybody can touch him.ā€

ā€œIā€™m just proud of him,ā€ Henry beamed. ā€œI canā€™t say it enough.ā€
