4. Jim Laker's Test Match Bowling Figures of 19/90
That shorthand stands for 19 wickets, 90 runs. In other words, out of 20 Australian wickets to fall at Old Trafford in 1956, England off-spinner Jim Laker missed only one.
Ten wickets in a Test match is considered an exceptional achievement; 19 victims is absurd.
By comparison, Laker's England colleagues sent down 123 overs between them and only managed one wicket.
Ten wickets in a Test innings has been repeated - Anil Kumble did it 1999 - but 19 in a match? We'll almost certainly never see it again.
