His first couple of homers on a legit field occurred in 14u. They cleared 315/10-12 foot fence down the line. Most of the high school JV fields freshman year didn’t have fences. He hit a couple into the bushes. His first varsity homer came in (I think) his fourth game soph year. He hit it into moving traffic way behind the fence. The field was too close to the street more than he hit it a cannon shot.
My son wasn’t a power hitter, per se. He was a line drive hitter who hit a number of pitcher’s mistakes out. None of his homers from LL through college ever went to the left of the gap.
