Explanation:

During scapular protraction at the SC (sternoclavicular) joint, the roll - slide mechanism occurs. The scapula moves anteriorly. The roll is in the anterior direction as the scapula moves forward. The slide is also in the anterior direction to allow smooth movement and maintain joint congruency.
