hitting control

Question
I'm thirteen and I just moved up to the big fields. The pitcher's are much better when I hit the ball I hit it decent. But my problem is I tend to strike out a lot mostly because I swing at bad pitches and watch good ones. How can i fix my control problem and learn at witch pitches to swing?

Answer
When you say you moved up that most likly means you are facing kids who throw better breaking balls and you started swing at those in the dirt and letting the good fast balls go.look to hit fastballs and take anything slow.You have started to worry about  hitting the offspeed and your mind locks up on fastballs sometimes.If you begin to take those offspeed and watch them you will start to know which is a ball and which is a strike.But if you swing at them you dont really see them.
