Getting measured on the speed gun can be particularly embarassing. I bowl seam up, and on occasion feel like I can get a bit of pace up. I did a Pitchvision event where they had speed guns set up, and the fastest I could manage was 62mph. We (recreational cricketers) bowl an awful lot slower than we think we do. The fastest kid at the event, who looked relatively nippy, was only closkced at about 71mph.
I did the NatWest bowling thing at the Oval last summer and bowling off about 4 paces (there was a tree right in the middle of the "Run Up") achieved 55mph. The quickest was a 17 year old, bowling off the same kind of run who achieved 79mph!
do you remember what this kid looked like by any chance?
