South Africa’s 3-day rout of West Indies included an obscure record for captain Dean Elgar.
He is one of the few captains who won a Test without scoring a run, taking a wicket or a fielding dismissal. Here is the complete list of captains who achieved this:

Note that Babar Azam did the same earlier this year.
There are some famous names here (including Bradman in his last Test in 1948).
No Indian captain here, although Clive Lloyd did this against India in 1976. That was the Test famous for the bouncer barrage and India being 97 all out with 5 batsmen unable to bat due to various injuries.
Meanwhile, here is the short list of Indian players whose side won a Test without any contribution by them:

Ishant Sharma achieved this earlier in the year. There is also Pujara with one of his rare ducks.
Also note 3 separate players in the test against NZ at Chennai in 1955-56, which is remembered for the long-standing opening record of 413 by Vinoo Mankad and Pankaj Roy.
TAIL PIECE: If you have any connection with Maharashtra, you can create memes about the Elgar Parishad.
