Few things to clarify, for a midway action what is the exact foot positioning for the delivery, where is the front foot in relation to the back foot as the back foot lands?
How to prevent the front foot twisting as it lands through the crease?
It should be pointing straight down the wicket but sometimes as I bowl it will twist to the batsmen's off stump and my delivery will follow in that direction.
What is a good speed for a bowler between the ages of 13-15?
I will be uploading a video but I forgot to take the camera to the nets today, luckily I go to the nets every day and play cricket every day!
