The World Championships were not yet a day old when news of the first two doping offences surfaced. 

Kelly-Ann Baptiste, a sprinter from Trinidad and Tobago who trains in the same Florida-based group as Tyson Gay, failed a drug test and was already on a flight back home before the first evening session was even underway yesterday. 

And Aaron Armstrong, also a sprinter from Trinidad and Tobago, missed two mandatory drugs tests.

Baptiste is the third fastest woman over 100m this year, clocking 10.83sec in Trinidad in June.It is not known what she tested positive for. 

This week, Britain's Dai Greene, the 400m hurdles defending world champion, said he feared that athletics was heading for a 'Lance Armstrong moment'. 

The number of athletes being found out is rising with alarming speed.

Turkey have 40 banned athletes and the World Championships' host country Russia have a similar number. 

Baptiste, the 2011 world championship 100m bronze medallist, joins Gay, Asafa Powell, Veronica Campbell-Brown and Sherone Simpson on the roll call of high-profile banned athletes.
