After a 12-month scouting trip paid off, the Melbourne Renegades are planning to unleash 15-year-old Afghan spinner Ahmad Noor on the Big Bash. Noor, born in Kabul , Afghanistan in 2005, has signed on for the full season and is expected to play as many games as the latest BBL fixture requires before Christmas, when Imran Tahir of South Africa will also join the squad. “Noor is someone we have kept tabs on for over a year,” Renegades coach Michael Klinger said.
