Thompson, a world silver medallist in the 200m at Beijing in 2015, has a wildcard entry in the 100m as the reigning Diamond League Trophy winner and cruised to 11.20 secs (wind -1.3 m/s) in the preliminary round.

Thompson, who did not speak with reporters after her race, will not be selected for the 200 in London as per Jamaica Athletics policy.

The next best qualifiers to the women's 100m semifinals are Simone Facey, Olympic finalist Christania Williams and Jonielle Smith.

In the absence of Usain Bolt, who has a wild card entry to London, 2011 world champion Yohan Blake made easy progress to Friday's semifinals of the men's 100m with a time of 10.21.

Blake took control after 30m and cruised to the tape ahead of training partner Jevaughn Minzie.

"The plan coming in today was to just take it easy," Blake told Reuters, adding that he was delighted with his form.
