Bowling changes – in a 20-over innings- after the mandatory first and second over, there can be 18 maximum bowling changes. Minimum 3 bowlers required to bowl in that inning.
e.g the first over is bowled by A-bowler followed by B-bowler in second over, now C-bowler takes over in the third over(replacing A). Below table explains the process.
