Speaking ahead of the second Test, Hazlewood said the abrasive nature of South African wickets was key to generating reverse swing, in contrast to the green seamers common in Australia.
"With [wickets in] Australia being the green seamers, it just doesn't get talked about at all," Hazlewood said. "The ball still looks new late in the innings if it gets that far. So it's more, you know, if you go back to SCG years ago, we definitely got reverse there every year, and then here in South Africa, [they're] just abrasive wickets."
Hazlewood's performance in the first Test included the dismissals of David Bedingham (lbw) and Wiaan Mulder (caught behind) through sharp movement off the pitch. According to CricViz, it was the most old-ball movement Hazlewood had produced in a Test since the corresponding Durban Test in 2018.
The bowler emphasised that the methods being used this time are entirely legal. He said the balance between hardness and reverse swing is important: "You probably want the ball a little bit harder and a little bit of reverse swing, rather than a lot of reverse swing and the ball soft. It's much easier to navigate as a batsman."
Hazlewood predicted similar conditions at St George's Park, though heavy rain is forecast for the first two days. "The conditions sort of dictate it," he said. "So there's probably more grass and seam movement if it's not reversing."
The second Test also looms as a potential recall for South African quick Kagiso Rabada, who missed the first match.
