[1] A right-arm fast-medium bowler and effective lower-order batsman, Amar Singh Ladha played in seven Tests for India before World War II.

Against England at Madras in 1933–34, Amar Singh Ladha scored 48 in the second essay after taking 7 for 86 off 44.4 overs in the visitors' first innings total of 335.

Amar Singh Ladha along with Mohammad Nissar formed part of a duo of fast bowlers for India.

[3] According to English cricket legend Wally Hammond, Amar Singh was "as dangerous an opening bowler as I have ever seen, coming off the pitch like the crack of doom".

Amar Singh also had an elder brother, Ladha Ramji, an aggressive fast bowler, who played a test for India against England in Bombay.

With his bowling partner Nissar, the two fast bowlers were the centre of attraction on the first day of the match being played at Lord's.

It was first Nissar who wreaked havoc with the English top order, dismissing the openers, Percy Holmes and Herbert Sutcliffe to reduce England 1 for 8 and 2 for 11.

At 19 for 3, England were in deep trouble, but the legendary Wally Hammond, who would later go on to praise Singh lavishly, mounted a recovery with his Captain Douglas Jardine, the pair added 82 runs for the third wicket before giving Amar Singh his first wicket in test Cricket, later, Nissar carried on his fine work and took three more wickets, cleaning up the middle order, while CK Nayudu (who was the Indian Captain, and who took two for 40 in England's first innings), and Singh mopped up the tail as England were shot out for 259.

In Wisden's report of the test, it was noted that, "Amar Singh bowled almost as well, making the ball curl in the air either from leg or from the off and causing it to come off the pitch at a tremendous pace."

From that point on, Jahangir khan, another Indian fast bowler, ran through England's middle order, taking 4 for 60.

However, Wisden heaped praise on the Indian fast bowler, stating, "When England went in a second time, Amar Singh bowled even better than before".

Amar Singh was also said to have had the ability to exploit the new ball well, making it swing both the ways, and when the shine was off, his "devastating breakback often penetrated the defense of well set batsmen, castling them comprehensively".

However, it is highly debatable whether India's other fielders were as good, as it is reported that many edges of Nissar's and Singh's bowling were dropped [citation needed].
