A hamstring injury to Morne Morkel means Kleinveldt will earn his fourth cap.
Rory Kleinveldt will get a chance to impress the South African selectors when he replaces the injured Morne Morkel like-for-like.
Kleinveldt is also a pace bowler and, although South Africa have already won the Test series against Pakistan, it will give the player a chance to show his ability.
It is a difficult time for fast bowlers to make it into the national side for the Proteas, with the pace attack of Dale Steyn, Vernon Philander and Morkel currently the best in the world.
Yet this is a good opportunity for Kleinveldt, who has been at best a fringe player for his country.
He made his début in 2012 against Australia, alongside the other three fast bowlers and last appeared in the Test side when Philander was unfit to face New Zealand. He has taken eight wickets in the five-day game to date, but has a high average of 42.50.
South Africa will be aiming to whitewash Pakistan to affirm their ranking as the number one Test side in the world. So when the match begins at Centurion on Friday, Kleinveldt should have a good chance of getting amongst the wickets.
Dolphins’ fast bowler Kyle Abbott has also been added to the squad as cover.
