Gibbs achieved the feat in the Caribbean, in St Kitts during the 2007 ICC Cricket World Cup, when he dispatched Netherlands leg-spinner Daan van Bunge over the ropes six times in a row.
And while four other players — including Barbados and West Indies legend Sir Garry Sobers — have done it before or since in professional cricket, Gibbs was the first man to hit six sixes on the international stage.
“I am really looking forward to playing in the first CPL. I love the Caribbean and have great memories of touring there. The people are lovely and although each nation is different, they all have that same warmth and charm that makes everyone want to go there,” said the 39-year-old.
“Many of the West Indies players have become my friends over the years and playing alongside them in their home countries will really be special.”
Gibbs joins fellow international stars Ricky Ponting, Adam Gilchrist, Ross Taylor and Pakistan Twenty20 International captain Mohammad Hafeez as big-name signings for the inaugural tournament that will take place across six countries in July and August.
Also confirmed are six West Indies franchise players — Dwayne Bravo, Chris Gayle, Sunil Narine, Kieron Pollard, Darren Sammy and Marlon Samuels.
“Despite some speculation in the press the announcement of which players will be playing for which countries, this information is still to be announced by the CPL. So as with the others the country Gibbs will be playing for is not confirmed,” the tournament organisers said in a release.
Gibbs’ international career spans 15 years and includes 90 Tests, 248 One-Day Internationals (ODIs) and 23 T20Is.
He has 35 hundreds for his country, 21 of them coming in ODIs — the most by a South African player. Gibbs has played a total of 164 Twenty20 matches around the world.
