LAUSANNE — Former 100-meter world record holder Asafa Powell wants his 18-month doping ban reduced to three months, arguing that he only committed a minor offense. The Court of Arbitration for Sport (CAS) says it has received an appeal from the Jamaican sprinter, who has been suspended from competition since his doping case was disclosed last July. Powell and three-time Olympic medalist Sherone Simpson tested positive for the banned stimulant oxilofrone at Jamaica's national trials last June. They were banned by a Jamaican disciplinary panel last month. Simpson has also asked for her suspension to be cut to three months. — AP
