English cricket chiefs have confirmed the playing conditions for a new 100-ball cricket format known as The Hundred, which is due to start in 2020.
Eight new city-based teams will play in the domestic competition over a five-week period, the England and Wales Cricket Board (ECB) said, adding that the white-ball contest would consist of 100 balls per innings with a change of ends after every 10 deliveries.
Bowlers can deliver either five or 10 consecutive balls, with each bowler allowed a maximum of 20 deliveries per game.
"The Hundred will help cricket to reach more people," ECB Chief Executive Tom Harrison said, after the first-class counties had voted 17-1 in favour of the playing conditions.
The new competition will also feature a 25-ball powerplay start for each team, with each bowling side allowed to take a strategic timeout.
