Having been a member of many cricket forums, this is the most knowledgeable and most active so best ask this here.
I am quite knowledgeable at cricket, but pitches baffle me completely. What I know so far is that pitches with grass on them are frightfully slow and also move off the pitch quite a lot off the seamers. Spinners hit the seam, so why does it not spin on green wickets?
What I know so far:
- Hard, green and light (orange) coloured pitches are good for pace bowling. Good carry as the ball kisses the surface.
- Grass creates seam movement because the grass and the roots creates miniscule undulations in and under the surface of the pitch for the seam to grip off and create an uneven movement.
- Lots of grass creates a slow pitch as the grass creates friction with the ball and slows it.
- The drier the pitch, the slower the ball comes off the pitch.
- The drier the pitch as the ball comes of it slower, the ball by a spinner has fractionally longer on the surface and grips and turns more.
- Dry tracks crumble as the day(s) goes on. Crumbled areas (which can be caused by footmarks or the ball landing) give the ball a great uneven area to purchase off and spin.
Whether a pitch is hard or soft depends largely on the soil type and also how wet the soil is. However, you can still get a dry, soft surface if the soil is of that type.
