Potgieter, 29, will arrive at the Ageas Bowl with Hampshire in a state of flux, following Wednesday’s red-ball retirement of stalwart Liam Dawson, and with Hampshire sitting rock-bottom of Division One, ahead of Friday’s home fixture against champions and current pace-setters Nottinghamshire.
He will remain with the club during their Blast campaign, which begins at Taunton on May 22, with his compatriot Tristan Stubbs due to arrive after the conclusion of his IPL stint with Delhi Capitals, and will also be available for their Championship fixtures against Surrey and Sussex in June.
Potgieter has a strong domestic record in South Africa, having taken 128 wickets in 50 first-class matches at 23.61, as well as 2,564 runs at 44.20, with five centuries and nine fifties, at an average of 44.20.
He has a pre-existing relationship with Hampshire’s head coach Russell Domingo, who was in charge of his at champions Gauteng in the recent CSA 4-Day Series, in which Potgieter scored 606 runs – the second-most for his team, at an average of 101 – and took ten wickets in seven matches.
In T20 cricket, he has scored 1,329 runs and taken 49 wickets in 97 matches, and picked up a best haul of 5 for 10 for MI Cape Town against Sunrisers Eastern Cape in the SA20.
