The bizzare superstition of Victor Trumper

VictorTrumper, the legendary Australian batsman from the golden era, had a bizarre superstition. While bowlers held no terrors for Victor, the sight of a clergyman wearing a "dog collar" worried the life out of him. Once the great S.F. Barnes got Trumper early in his innings and Vic said: "I knew I would not score with all those clergyman about…"

Which reminds me about superstition of another cricketer. Amar Singh from India.

Ram Guhawrote about it.

Amar Singh died in May 1940, six months short of his 30th birthday. (He was consumed by a mysterious fever: indeed, a month before he passed away he had been playing cricket). Even while he lived, however, he was obsessed with the idea of death. One who knew of this obsession was the great all-rounder, Learie Constantine, his colleague and rival in the Lancashire League. When Learie's club, Nelson, played
Amar Singh's team, Colne, the West Indian would come to the ground dressed in black. Naturally the Indian would ask what had happened, and Constantine would answer that he had just attended the funeral of a friend. This ruse was intended to put his opponent off his game, to so disturb him psychologically that he might not give of his best. Perhaps of all the tributes that ever came Amar Singh's way this was the most remarkable; that Constantine, a supremely gifted all-rounder himself, could not trust solely to his cricketing skills when playing against him.
