There are 3 to 4 playing pitches in a cricket ground, Why?

 

1. All grounds have more than one pitch- this is a demand as a fresh pitch is needed for each match, and pitches take time to recover and prepare. Big grounds will have 20 to 30 pitches across the place, while indeed veritably small grounds

 will have 3 or 4. 

2. THE MIDDLE PITCH IS USED TO PLAY ALL KINDS OF CRICKET MATCHES

3. THE PITCHES AT THE SIDE ARE USED DURING THE TRAINING SESSION
