Play Turn Animations with mouse axis??

I have an animator of type generic, containing 1 blend tree which is 2D Cartesian, the player can walk forward, backward, strafe and jump. I have 2 turn animations that I would like to get played as the player moves the mouse left or right(like TPS games), how would I accomplish that??? EDIT: I kept trying several times, one try was making a 1D blend tree containing the 2 turn animations and another 2D blend tree containing all other animations
