Jansen's gritty knock of 85 and hauls of five for 33 and one for 34 have, in fact, helped him advance in all three lists of the Test Player Rankings as he has also gained 13 places to reach 56th position among batters.
The left-arm fast paceman is the first Proteas bowler to occupy the top spot since Kagiso Rabada in November 2024 and the first from his country to become the top-ranked Test all-rounder since Vernon Philander in August 2014.

Bavuma is now only behind England's Harry Brook and with a chance to become the first South Africa player to top the Test batting rankings since AB de Villiers in November 2015.
Others to move up the Test rankings include Australia fast bowler Scott Boland, who is up three places to sixth position for a haul of five for 81 while South Africa's Wiaan Mulder is up 10 places to 43rd after finishing with five wickets across the two innings.
