Johannesburg - Proteas rookie Faf du Plessis joined the International Cricket Council's Test rankings for batsmen in 56th position on Monday after a spectacular debut against Australia in the drawn second Test in Adelaide.
Du Plessis, called up as a replacement for injured all-rounder JP Duminy, made 78 in the first innings and an unbeaten 110 in the second to save the match and keep the series square at 0-0 with one match to play.
However, while Du Plessis made an impressive first appearance in the latest global rankings, South Africa's top order batsmen slipped in the table.
