In Tennis World Tour's Career mode, your main goal with your avatar is to become the best in the entire world. To do that, you'll have to learn to manage both your schedule and your form. Take part in an exhibition match or a tournament, train or rest — your choices are crucial and will have an impact on your career. If you string multiple matches together, or travel relentlessly around the globe, fatigue will sneak up on you, your performance will be affected, and you risk injuring yourself.
