After soph year of high school ball and travel the coaching staff convinced my son to do something he had been tuning out from me for a year. They convinced him he had to stop pulling everything. He was hitting flies and grounders to the right side on pitches he should have been ripping to left center.
He started training in November. He didn’t feel right with it until January. It was undoing a process that had been in place from when he started playing. He has always been able to pull everything in the past.
Going with the pitch didn’t change pulling the ball or affect his power. What changed is outside pitches that were soft flies or groundouts to the right turned into line drives to left center. His average went from .340 to .520 (part of the improvement was getting stronger).
Before this change if I was coaching against my son I told him only the third baseman would be on the left side to prevent the bunt for a hit.
