Making a good accurate throw is an important part of playing baseball. The best way to learn to throw is to practice. Go out and play catch with your friends or parents. The more you throw the better you will get.
Stance
Anytime you make a throw in baseball it is important to be set and balanced. Don't try throwing off of one foot or while you are running, this will just result in a bad throw and the runner will not only be safe, but will likely get to advance another base.
Gripping the Ball
The ball should be gripped with two fingers and the thumb. Some young players with smaller hands may need to use three fingers. Try to hold the ball out on your fingertips and not back in the palm of your hand.
The Throwing Motion
The throwing motion is complex and the best way to learn it is to practice. Here are some of the steps to a good throw for a right handed thrower (reverse for left handed):
Get a good grip on the ball using two fingers and your thumb.
Stand sideways with your left shoulder pointed toward your target.
Plant your right foot solidly on the ground.
Step forward with your left foot, pushing off with your right foot.
Focus your eyes on your target.
Throw the ball overhand using your entire arm and your wrist.
Follow through with your arm always pointed toward the target.
Overhand Not Sidearm
Many young players tend to throw the ball sidearm. This takes away power, accuracy, and can strain the arm. When you practice work on throwing overhand.
Your Whole Body
Your entire body should be a part of your throw. Don't just throw with your arm. Your shoulders, legs, torso, should all work together with your arm to throw the ball.
Aiming the Ball
One thing you should never do is "aim" the ball. You "throw" the ball. With enough practice throwing an accurate ball come naturally. Once you start trying to "aim" the ball you are sure to miss your target.
Where to Target the Ball
When you throw the ball you throw it directly at the other player's glove or chest. You should throw through their glove. Don't try to get the ball to land on their glove. You want to throw a straight line-drive ball right through their glove. If you are very close to the other player, then throw the ball underhand.
