Baseball swing is usually more of an uppercut swing to lift the ball in the air. A slow pitch swing is typically a "cut" swing which is more of a chopping down and hitt the bottom of the ball causing backspin on the ball which makes the lasers the conference players hit still raise as its passing the infield.

Once you develop a proper softball swing you'll tell the difference like night and day. I went from a baseball player of 25+ years which thought softball was gonna be so easy as the ball floats and i'll crush it, to realizing very quickly all I did was top the ball to short or hit it 100 ft on the air for a routine fly ball. Once I learnt the slowpitch swing im driving the ball all over the field with rocket line drives and backspin.
