“The glorious uncertainty of the law” was a toast made in 1756, after Lord Mansfield overruled some old legal decisions. Several sports and games have been noted for their “glorious uncertainties,” with the term usually applied to the game of cricket.
 
“This innings amounted to only 28, thus losing the match by 11; and fully proving the glorious uncertainty of cricket” was printed in Bell’s Life in London and Sporting Chronicle (London, UK) on June 21, 1835. “The Sheffielders then took the bat, appearing confident of success; but the ‘glorious uncertainty’ of this noble and manly game (cricket—ed.) was again made apparent” was printed in the Sheffield (UK) Independent on July 1, 1837. “Nothing could shew the ‘glorious uncertainty’ of ‘cricket’ as well as ‘law’ than the result of two Matches in the same week” was printed in The Sporting Magazine (London, UK) in August 1840.
 
“Cricket is an uncertain game”—without “glorious”—has been cited in print since at least 1848.

Cricket is a bat-and-ball game played between two teams of 11 players each on a field at the centre of which is a rectangular 22-yard-long pitch. The game is played by 120 million players in many countries, making it the world’s second most popular sport after association football. Each team takes its turn to bat, attempting to score runs, while the other team fields. Each turn is known as an innings (used for both singular and plural).

Is Cricket generally more ‘gloriously uncertain’ than other popular sports?
October 14, 2015, 5:39 AM IST

‘Glorious uncertainties of the game.” The original cricket cliché, the one which you can’t even blame on Ravi Shastri. The earliest use of the phrase in cricket writing that I could trace was an article by the great Neville Cardus on Don Bradman in 1930, and scores of other writers and commentators have appropriated the phrase, including an extremely irritating gentleman with a fake Aussie accent on All India Radio.
