BIRMINGHAM, (Reuters) - Before Imran Tahir left his native Pakistan in 2006 he was approaching 30 and international cricket was passing him by. But a chance meeting with a South African woman changed his life and the fortunes of Graeme Smith's team. After following her to South Africa, he became a citizen there and soon came to the notice of the selectors. Now he could become their World Cup saviour, guiding the team to the title for the first time. Tahir was sad as he was forced to watch from behind the boundary ropes.
