AddForce() always throws towards the ground

I have a small test scene with a single model prefab and a single script applied to that prefab. In my scene the model picks up and throws a ball.

No matter how I modify AddForce the ball never throws forward. Here is my code:

GameObject[] ballsInGame;            
public Transform ballIAmHolding;
Rigidbody ballBody;
float throwPower = 50f;

void Start () {
            ballsInGame = GameObject.FindGameObjectsWithTag("pickupable");
}

    void Update () {

//pickup and throw
        if (Input.GetKeyDown("f")) {
            anim.SetBool("pickupBool", true);
        } else { anim.SetBool("pickupBool", false); }
        if (ballIAmHolding == null) {
            anim.SetBool("throwBool", false);
            foreach (GameObject ball in ballsInGame) {
                float distDiff = Vector3.Distance(transform.position, ball.transform.position);
                if (distDiff < pickupDistance && Input.GetKeyDown("f")) {
                    ballIAmHolding = ball.transform;
                }
            }
        }
        else {
            ballIAmHolding.transform.position = rightHandBone.transform.position;
            anim.SetBool("pickupBool", false);

            if (Input.GetKey("c"))  {
                Debug.Log("C DOWN");
                anim.SetBool("cockBool", true);
            }
            if (Input.GetKeyUp("c")) {
                Debug.Log("C UP");
                anim.SetBool("cockBool", false);
                anim.SetBool("throwBool", true);

                ballBody = ballIAmHolding.GetComponent<Rigidbody>();
                ballBody.AddForce(transform.forward * throwPower);                    
               

                ballIAmHolding = null;
            } 
        }
}

ballBody.AddForce(transform.forward * throwPower); should throw the ball forward from the player model that the script is attached to. The game throws the ball down every time.

Thanks!!
