Rana Naved-ul-Hasan, the former Pakistan bowler, has signed for Derbyshire for the Flt20. He turned down the chance to join Hampshire or return to Sussex, where he has played for six seasons.
Having taken 107 T20 wickets, Naved is regarded as specialist in the short format of the game. He was the top wicket-taker in Australia's Big Bash League, with 15 victims for Hobart.
Naved, 33, will be available throughout the Flt20 alongside Australia batsman Usman Khawaja who joins for the whole of the 2012 season. Khawaja could be called up for Australia A in July, in which case Naved would be available for County Championship and CB40 cricket.
"We wanted our second overseas player to be a match-winner," Derbsyhire head coach, Karl Krikken, said. "Rana's performances throughout his career demonstrate we have ticked those boxes with this signing."
Chairman Chris Grant added: "To beat the attention of opposition counties to the signature of a standout overseas player in Naved is a massive coup for the club. He has proved to be an inspirational performer in T20 cricket around the world, as well as boasting exceptional pedigree at one-day international level with Pakistan."
Naved played 74 ODIs for Pakistan, taking 110 wickets at 29.28, his last match coming in 2010 against Australia at Perth. He also helped Sussex to T20 finals day in 2007.
"Not only do I expect him to help us win matches, he is also a very entertaining player to watch," Grant said. "His skills and larger than life personality have added an extra dimension to T20 nights in Hobart of late and I'm sure that will be replicated at the County Ground this summer."
