How are you doing? My name is Kris Totten, with Akadema Sports Equipment, I'm here for About.com. I'm going to show you how to throw a two-seam fast ball.

What's the Purpose of a Two-Seam Fastball?

The two-seam fast ball is designed to move and deceive the hitter. It's a little slower than the four-seam fast ball, generally 1 - 2 miles an hour.

Setting Up for a Two-Seam Fastball

You are going to want to put your fingers on the seams. Your middle finger and your index finger are going to be sitting right on top of the seams. You are going to go through all the motions the same, just like you are throwing a four-seam fast ball, a curve ball, a change-up. The motion stays the same, the only thing your are change is the grip on the baseball.

Ready Position for a Two-Seam Fastball

We are going to get into our ready position, square up your shoulders to the target. Now we are going to take that step back, get that momentum going this way. Now you are going to pivot. That's going to help you get to your balance point, which is step three, and explode toward your target with that two-seam grip.

Balance When Throwing a Two-Seam Fastball

Now, one of the common problems that kids have today is that they aren't maintaining a proper balance point. They are getting up and rushing to their target and their arm is dragging behind them. They have to keep their weight back on that back leg to allow that arm to get up into a healthy arm slot. Keeping that weight behind them and get out in front of the target instead of losing your balance and falling toward your target. You've got to stay back on that back leg, get that arm up, and explode toward your target.
