What I see is the back elbow getting ahead of the back hand. Some call this dipping the back shoulder. This is very common with young kids who have timing issues. In terms of hitting a high or low pitch. We adjust the bat angle. On a high pitch we start the elbow higher and have less bat angle. Elbow and hands must always be above the plan of the pitch. Our team faced a rise ball pitcher this weekend in the gold showcase. Last year this team beat us and we got one hit. This year I worked with the girls on how to hit a rise ball. We had 10 hits and beat the same team 7-2.
