I am a power hitter, but lately i have been having a great deal of trouble getting huge hits because i keep on top-spinning the ball. I will crush a ball and it will land in front of the left fielder when a kid a third of my strength will use backspin to send a ball sailing 350 feet. I recognize that i swing much like piazza and edmonds in that i come up at the ball and love to drive low pitches. The thing that makes this difficult for me is that i dont want to change my swing a lot since i still hit for great power some of the time. Does anyone have any tips for practicing hitting the bottom half of the ball or any idea for somthing i can do to not topspin it?

> Bauer, If you are hitting the ball with overspin too often, you are probably rolling your top hand into the ball. Try and hit the ball with a palm up palm down approach. As far as aiming 1/4 inch under the ball, that is nonsense. If a guy is that good, just hit it dead center. If you swing into the path of the ball, you will hit your share of rising liners. Elbow into the slot and then palm up palm down at contact and you should show improvement.

Topspin is not (necessarily) caused by hitting the top of the ball. Underspin is not (necessarily) caused by hitting the bottom of the ball.
If the angle of the bat's path is steeper upward than the downward path of the ball, the rising bat will create topspin on the ball if the bat strikes up the back of the ball. If the ball is hit center-of-bat on center-of-ball a hard high popup or flyball will result.
If the upward swing hits above or near center a topspin grounder will result. If struck below center a topspin flyball will result - that's what you describe.
It is the 'brushing up' the back of the ball that causes topspin. Hitting through the ball (center on center) reduces excessive spin. But the more severe the swing angle the harder that is to do.

From what you describe you are uppercutting the ball too much.

If you change your swing plane to a smaller upward angle you will probably drive more balls with less topspin.
The upward angle may be caused by sitting back too much or simply swinging up too much.

Similarly brushing down the back of the ball by swinging down through it will create underspin. Where you strike the ball determines whether you get a grounder, liner or fly. All three can have underspin, created by the downward angle of bat to ball.
