The lesser-known South African bowler Wiaan Mulder took 3 wickets for 1 run against the West Indies.
Is this the record for the best 3-wicket haul in Tests? No, but it comes close.

The best is 3-0 by Benaud against India in 1959-60.
Mulder is one of three to take 3-1.
Here you can also see Alok Kapali’s hat-trick innings.
The best for India is 3-8 by RK Chauhan against SL in 1993-94. Three others have taken 3-9: Ravi Shastri (on debut), Maninder Singh and Umesh Yadav
