Create an Enemy Animation

Hi! I´m new in Unity. I'm trying ti create an Enemy which can throw a ball to an object. I created tow animations for that. One is the "waiting" animation that is a loop and repeats over and over again. Between this loop there is a "fire" animation which the Enemy Throw a ball to this object. The enemy have to spawn the ball in the hand of it every time it was thrown... Probably because I'm new it is hard... Can someone help me? Thanks!! PD: Sorry for my english...
