Linde, since his debut for Western Province in 2012, has featured in 75 T20s in which he has picked up 77 wickets.
A left-arm spinner and a handy lower-order batsman, Linde is currently in India with the South Africa 'A' team and will join the Proteas upon their arrival. He scored a quickfire 52* in the second game of the five-match series, and has picked up three wickets in as many games so far.
The rest of the squad is expected to depart for India on Friday.
