At the heart of the victory was Kagiso Rabada, the 21-year-old fast bowler to whom, for the past year, Steyn has symbolically been passing South Africa's pace baton. Here, Rabada simply ran away with it, destroying Australia in the second innings with pace, bounce, seam, conventional swing, reverse swing, searing yorkers, and the ability to target cracks in the pitch. In short, almost every weapon that makes a fast bowler dangerous. He finished with 5 for 92, and seven wickets in the Test.
