This meet was announced as the last competition for Usain Bolt . The race was won by Justin Gatlin of the United States, ahead of Gatlin's team - mate Christian Coleman, with Bolt finishing third . </P> <P> In the first semi-final Justin Gatlin qualified but seemed to struggle, losing to Akani Simbine . In the second semi-final, 2011 champion Yohan Blake barely held off the home town Reece Prescod . Run into slight headwinds those semis were unimpressive, slower than ten seconds . In the third semi-final, Christian Coleman was out to a significant lead, but Bolt got into his running form and made up the gap, then eased off at the finish . The crowd sensed there ws a lot more in the tank, Coleman's 9.97 the fastest semi . </P>
