Wahab won widespread plaudits for a fierce spell of fast bowling which forced Watson to duck into and under a series of short-pitched deliveries in the game at the Adelaide Oval.
Wahab even applauded the Australian and blew him a kiss as Watson survived on his way to helping the co-hosts to a six-wicket victory.
"It was a good battle on the field. U played well. @ShaneRWatson33 . Wishing u best of luck for the semi's . #Respect," tweeted Wahab, who was fined 50 per cent of his match fee for his exchanges with Watson.
Watson ended Friday's game on an unbeaten 64 off 66 balls but he was dropped on four by Rahat Ali at fine leg off a 145kmh Riaz bouncer.
