Although one effective baseball swing can deviate from another in a few areas, there are always some traits the powerful swings have in common. Contrary to popular belief, things like one's stance or first step are not all that important. Instead, the perfect swings all have a good shift of weight, a drop of the rear elbow, a solid hip turn, and a quick flick of the wrists. These factors allow one to get the bat from a starting point to the point of contact as quickly as possible. Any physics major will tell you this is the way to generate as much power as possible. While the perfect baseball swing can be accomplished only with countless hours of practice, there are still some things to learn about it prior to hitting the field. After all, hours of practice means nothing if you are practicing the wrong technique. Prior to grabbing your bat, read below for information on the perfect baseball swing technique.
While most people tend to stand with their knees slightly bent and shoulder-length apart prior to swinging, this does not really matter. If you look in Major League Baseball, you will see a plethora of different stances, all of which have obviously been effective. Your stance should be about comfort. As long as you feel comfortable in a stance and it will allow you to eventually shift your weight, it is fine. Worry about getting the bat to the point of contact as quickly as possible from your personal stance, not altering your stance in an effort to quicken your swing. The latter event is unlikely to happen.
The First Step
Your first step is important to your baseball swing, but the manner in which you do it is actually trivial. You do not need a giant step forward to generate power. Actually, the first step is not used for power at all, but rather as a timing mechanism. Professional baseball players have all sorts of first steps, including backwards and, for some, no step at all. Step however you feel comfortable, as long as it allows you to time your swing effectively.
When you are going to swing, you will start by simultaneously bringing your rear hip forward and dropping your rear elbow to that hip. The movement of your rear hip is really where all of your power is generated, so it should truly fly forward as fast as possible. Only after this hip is rotated forward should your hands follow. Until you alter the placement of your bodyweight through a hip turn, your hands and head should remain relatively still.
As your hip flies forward, your hands can then follow suit. A flick of the wrists will allow the bat to come through the hitting zone with maximum power, and a turn of the wrists gets the bat into position to hit. Turning your wrists over also allows you to garner more power. As you finish the swing, make sure your bat ends high near your shoulders. Your bat should come through the hitting zone near your hips, but then end up much higher as a result of you dropping your elbow.
