Ok kiddo, let me explain.
Have you ever played catch with a ball using your hands? Well, imagine playing that game but instead of a ball, you use a smaller and lighter ball called pelota.
Now, when you play this game with friends, you usually use your hands to catch the ball. But in bare-handed pelota first league doubles, the players are not allowed to use any gloves or mitts. That's why it's called "bare-handed."
This game is played with two players in each team, which is why it's called "doubles." The court is like a big rectangular box with walls on three sides that are really high. The court also has a net that divides it in two.
The players use their hands to hit the pelota against the front wall, and the other team has to catch it before it bounces twice or hits the ground. If they manage to catch it, they get a point. If they miss it, the other team gets a point.
But it gets trickier because the players can hit the ball in many different ways, such as making it bounce off the walls or using special moves to make it harder to catch.
So, in summary, bare-handed pelota first league doubles is a game where two teams of two players each use their hands to hit a small ball against a wall and try to score points by making the other team miss catching it. And they do all of this without using any gloves or mitts! Cool, huh?
