In one sentence, describe what the following article is about:

Adjust the ball so that one surface is on top with the horseshoe-shaped stitching around it. Place your middle and index fingers over the ball. These fingers should cross over stitching twice. Pull your thumb back behind the ball and place your ring finger beside it. This grip makes your throws stronger and more accurate, which are essential qualities of good shortstops. Practice by throwing the ball up in the air. Catch it and quickly rotate the ball so the stitching is near the top. Finish by applying the four-seam grip. Start with your body sideways. Point the shoulder on the mitt side of your body towards the target. Move the foot on your throwing side back, firmly planting it behind you. You’ll need to use this stance to generate power and accuracy. Practice the mechanics until they feel comfortable. As you plant your throwing foot behind you, draw back your arm. Hold the ball so it faces the ground instead of your target. When your arm travels back as far as it can go, you can fire the ball at the target. Balance is essential to a hard, accurate throw. Don’t rush. Bring your arm forward. As you do so, the face of the ball will turn inward until it faces the target. Your arm functions like a whip. Use your fingers and wrist to generate power. Remember that you’re throwing the ball with your entire body. Follow through by bringing your throwing arm forward after you’ve released the ball. The middle of the body is a big target. Balls thrown to this area are easier to handle. Don’t try to land the ball in the person’s glove. Instead, pretend that you’re throwing the ball past them, since you’ll need to throw harder and faster. Practice this by picking a spot on a wall and trying to hit it. To hit a moving target, you’ll need to anticipate where the glove will be. Aim the throw so that it’s a little ahead of the target. To get out quick runners, you’ll have to change your style sometimes. For a slow-rolling ball, you can try plucking the ball with your bare hand. Spread out your fingers so you have the best chance of getting the ball and adjusting your grip. This throw is often inaccurate, so you’ll need to judge whether or not you can get the ball to the target before the runner. Keep your throwing hand near your glove. Plant your front foot when the ball hits your glove. Move the ball into your throwing hand. You may have to use a side-arm throw to get the ball away sooner. Plant your throwing foot as the ball leaves your hand. This kind of throw is useful for balls on the edge of your range. Catch the ball in your glove. Spin away from your target. When your eyes find the target again, throw the ball as you normally would. This throw is tough to get right, so practice finding first base after spinning.
