You have lost weight, and this problem will occur without corresponding exercise strength. /kloc-more than 0/80 times, your shooting power only needs the power of raising your hand, plus a little inertia. Now that your inertia is small, it is natural to increase your strength accordingly. If it is heavy, you should play lower, and if it is light, you should jump higher. So you have to strengthen your strength, and then do the corresponding shooting practice, and soon your hand will come back.
The most important thing is to have confidence. The most important thing for a pitcher is to keep telling himself "I can shoot".
