Animator transition help

I've created some animations for my enemy including transitions to animations such as "IdleToChase". What I want is to play the animation with a script using: "anim.Play("IdleToChase"); and then once that animation has finished, it will switch to the connected animation which is the Chase animation but it doesn't correctly.

This is my animator:

I can't figure out why but that's most likely due to my lack of knowledge of the animator so i was wondering if someone could help me understand what's wrong and how to fix it?
