PITCH & ROLL

Rolling is an important process in cricket - it improves pitch performance by compacting the soil, reducing live grass cover and making the pitch more smooth and uniform. This improves both pitch performance and pitch safety. Good preparation ensures that all results are possible but that the pitch does not decide the result of the game. Just as under-rolling a pitch can have an effect on the game of cricket, over rolling can have negative effects too.
? The more a pitch is rolled the harder and better it plays
? Rolling slowly helps compact the pitch
? Heavier rollers help get the pitch harder at depth
? Any pitch problem can be cured by just rolling it more
