Cricket is a bat-and-ball game played between two teams of eleven players on an oval-shaped field, usually between 150 and 200 yards in diameter, at the centre of which lies a 22-yard long pitch. One team bats, trying to score as many runs as possible, while the other team bowls and fields, trying to dismiss the batsmen and thus limit the runs scored by the batting team. A run is scored by the striking batsman hitting the ball with his bat, running to the opposite end of the pitch and touching the crease there without being dismissed. The teams switch between batting and fielding at the end of an innings. In professional cricket, the length of a game ranges from 20 overs of six bowling deliveries per side to Test cricket played over five days. The Laws of Cricket are maintained by the International Cricket Council (ICC) and the Marylebone Cricket Club (MCC) with additional Standard Playing Conditions for Test matches ("Tests") and One Day Internationals (ODIs).
William Joseph "Bill" O'Reilly, often known as Tiger O'Reilly, was an Australian cricketer, rated as one of the best spin bowlers ever to play cricket. He delivered the ball from a two-fingered grip at close to medium pace with great accuracy, and could produce leg breaks, googlies, and top spinners, with no discernible change in his action. As well as his skill, O'Reilly was also known for his competitiveness, and bowled with the aggression of a paceman.
