Early on my playing career my swing did not translate from baseball to softball. In baseball there is no such thing as DBO's, naturally you swing for the fence/gaps/etc. When I first got into E ball I had my fair share of DBO's, these weren't moon shot homeruns, they were hard line drive home runs. Regardless a home run is a home run. I don't think moving up a level changes anything. Good teams save there homeruns for when they need to use them. I rarely see the best teams in our area every hit solo homeruns. They string hits together and do not waste there homeruns. It might help you in certain situations, but I have found these things to be true.
1. Know your swing, I absolutely hate when people aren't accountable for their swing and say OOPS. You know your swing. You know what you're capable of. If you are in a game and there are no homeruns or homeruns left make an adjustment, which leads me to my second point...
2. Bat control. Since my swing was all or nothing I had to learn to have BAT CONTROL. Often, mostly new players want to go up there and swing as hard as they can. This isn't some pick up game where people can see who hits the ball the farthest. When I first got into the game, I struggled because I had an all or nothing swing (good chance of it going out or total weak swing). I got scared to swing hard because I knew there was a chance of it going over, but since I had no bat control if I tried to alter my swing it was a lame pop up or ground ball. Learn to do both. BP BP BP BP, can't stress this enough. Work on line drive swings. Back side swings. Situational hitting.
3. Make adjustments. I think this is an often overlooked part of the hitting game. You can start to get tendencies of how the pitcher is throwing to you. Is he constantly throwing you low pitches, high pitches, quick pitches etc. Where do you often hit the ball out? Do you naturally hit certain pitches differently, pop up, home run, line drive, grounder, etc? Personally, I like the low ones and hate high ones. I try to stand back in the box to get that low pitch adjustment. If I have a guy throwing low balls I can move up.
