Glamorgan have signed South African international batsman David Miller as an overseas player for the NatWest T20 Blast campaign.

Miller arrives on Saturday and will be available for six T20 Blast matches, starting with Essex Eagles on July 23, with his last match set to be against Surrey only 12 days later in a packed schedule.

Miller is available because he has not being included in the South Africa A 50-over squad that will compete in a triangular series against India A and Afghanistan A which starts on July 26. It is expected he will be part of the four-day squad that play India A in two four-day matches, starting on August 12.

He has played 52 T20 internationals and 99 one-day Internationals for South Africa with previous experience in the NatWest T20 Blast for both Durham Jets and Yorkshire Vikings in previous campaigns. The white-ball specialist has enjoyed successful spells for St Lucia Zouks in the Caribbean Premier League and in the IPL for the Kings XI Punjab.

He adds to a strong South African contingent in Glamorgan's middle order which also include Kolpak-registered Colin Ingram and overseas player Jacques Rudolph.

Miller's last outing in Cardiff was at the end of June for South Africa in the third NatWest International T20 when England were victorious.

"We are delighted to sign David Miller for a six-game stint," said Hugh Morris, Glamorgan's chief executive and director of cricket. "David is a fine batsman, with a wealth of experience in T20 cricket. He is a match-winner and a finisher, proven to be one of the most destructive batsmen in the game at both domestic and international level.

"Hopefully his signing will add depth to our batting and boost our prospects of replicating last season's form when we secured a home quarter-final in the knockout stages.

After four matches Glamorgan currently sit in a qualifying position from the South Group having won two games against this weekend's opponents in Cardiff: Sussex Sharks and Essex Eagles.
