Olympic star Usain Bolt held off the field to win the 100 metres Friday at IAAF Diamond League Monaco event, while Canada's 4x100-metre men's relay team of Andre De Grasse, Aaron Brown, Brendon Rodney, and Gavin Smellie was disqualified after a bad exchange. 

Bolt edged American Isiah Young to win in a season-best time of 9.95 seconds.

"It's always good to get a win. My time is going down at the right time," the Jamaican said, looking ahead to the worlds. "Everything is coming together."

Young's time of 9.98 was 0.01 shy of a new personal best, while Akini Simbine of South Africa (10.02) beat out Chijindu Ujah for third place in a photo finish.

"I was so close to Bolt at the end of his great career. Couple of days ago I was told I will run the 200 in London, so this sub 10 is great preparation for that," Young said. "I need to execute well and then I can attack a medal in that event."

Bolt is retiring after the world championships in London next month.

De Grasse and the rest of Canada's team failed to finish in the six-team relay field. 

The disqualification came after a fumbled exchange between Rodney and De Grasse, the team's anchor.
