With wood bats a hitter can’t muscle a fisted pitch over the infield. He’s more likely to end up with a bat handle in his hand.
A lot of times the difference between a D1 and other level isn’t the swing. It’s a combination of metrics. I can think of two local kids who had sweeter swings than my son. In fact, I would have put their swings up against anyone. I saw both repeatedly each year in travel ball and one in high school. One went on to be All Centennial and a D3 All American. The other was All PSAC.
What these players didn’t have was foot speed, strong arms and size. They were both 5’9”. But they were strong and could drive the ball. But if you can only play first in D1 your options will be limited.
The fields are usually somewhat in correlation with the quality of the league.
Back when I played college summer ball I had a teammate who played for a CWS team. He hit .300+ with some power over the college season. He hit about .140 in summer ball. He didn’t want to be there. His coach set him up with the team. He just wanted to go home and relax after the CWS.
