Nigel Mansell was edged out of pole position by Al Unser Jr late in yesterday's qualifying session for today's Cleveland IndyCar Grand Prix, writes Toni Toomey. When the session began Paul Tracy set the pace, but Mansell appeared to have the pole locked up until Mario Andretti, his team-mate, pushed him off the track. As Mansell tried to regain the balance of his car, Unser Jr, who had been labouring in the slower Penske, snatched the pole from him by four-thousandths of a second. Meanwhile, rumours have cooled regarding Mansell's possible return to Formula One next year. 'Wherever I am, the competitive juices will be flowing,' Mansell said. 'Right now I have a major challenge right here.'
