Cape Town - The Proteas have added off-spinner Dane Piedt to their squad for the third Test against New Zealand, set to take place in Hamilton on March 25.
Piedt is expected to join the Proteas in Wellington - the venue for the second Test - sometime over the weekend, subject to visa approval.
The Proteas initially opted to go into the series with just one specialist spinner in the form of Keshav Maharaj, but looking ahead they have decided that they need another option for the series decider.
The first Test in Dunedin was drawn last week, but it did see New Zealand field two spinners in Jeetan Patel and Mitchell Santner.
Piedt will obviously not arrive in time to be considered for the second Test, which gets underway on Thursday morning (SA time).
The 27-year-old has played in 7 Tests for South Africa, the last of which came against the Black Caps at Centurion in 2016.
Piedt had fallen out of favour in the longer format, with selectors backing Maharaj and Tabraiz Shamsi in Australia. He has taken 24 Test wickets.
