LONDON - New Zealand cricket captain Brendon McCullum confirmed Tuesday he has signed for the Birmingham Bears for the defence of their T20 Blast title. McCullum joins the Bears -- Warwickshire's T20 name -- on a seven-match deal after playing a major role as New Zealand reached the World Cup final, where the Black Caps lost to co-hosts Australia. "The Birmingham Bears had a great season last year, including winning the T20 Blast, and hopefully I can make a big contribution and ensure that we can progress in the tournament," said McCullum.
