South African speedsters Dale Steyn and Morne Morkel were on top of Watson and his opening partner David Warner (5) at the start of the chase. But once the star all-rounder cut loose, he was unstoppable.
Watson smashed eight fours and two massive sixes in his breathtaking knock. He got to his fifty by pulling one off Wayne Parnell over deep square leg in the 10th over. Three balls later, Parnell dropped Watson while fielding for Robin Peterson at deep square leg.
