Questions & Answers
It is the 16th birthday of my son. He uses this, along with a 4.5 oz baseball and a regular (5.5 oz) baseball, as part of his off-season For an 8 year old, I would not suggest a training program using weighted balls. In my opinion, he would be better off practicing good mechanics and throwing long. Our training program began when our son was 14 years old with weighted balls. Training with weighted balls can be found on the Internet. Some very good information can be found on this website.
A little over half an ounce. There is a slight difference in weight between a regulation ball and this fanny My shoulder surgery has left me with the need for this.
