I am predicting a repeat of his heat win time of 10.10 will be enough. Maybe a 10.06- 10.08 gets him safer if he finishes third. Simbine is a lock to go through if not injured or a DQ.
Other chances are Cejhae Greene of Antigua [10.02 sb but ran out of Worlds heat in 10.17 then 10.16 in his heat to win a time qualifier here],
Edoburun of England. slow heat time of 10.27 but has a 10.07 this year
Conroy Jones of Jamaica, 10.28 in his heat but 6th at nationals in 10.10 and a 10.00 PB this year
E. Harrison Jr of Trinidad. Ran his PB of 10.08 this year but lucky to run a time qualifier here in the heats with 10.37
and Oghenebrume of Nigeria: 10.12 PB this year but slow heat run of 10.36
