Pateo la pelota

The correct sentence would be:

Soy parte del equipo de fútbol Americano. Para poder lanzar el balón mejor, pateo la pelota.

This sentence means:

I am part of the football team. In order to throw the ball better, I kick the ball.

So this sentence uses the verb ser conjugated as soy that matches the first person singular. On the other hand, pateo is the conjugation of the verb patear that also matches the first person singular. Another important verb is lanzar which is given in infinitive, the most basic form of Spanish verbs.
