Tennis is an international sport and each year there is a regular programme of tournaments and championships. Player's performance in these events determines their seeding, or world ranking.

If you play or are interested in tennis it's always a good idea to watch the professionals in action whenever you can. You'll start to see how they use tactics to outplay their opponents.

It's also interesting to see how play differs on different court surfaces. Some players prefer the slower game of the clay courts, others excel at the high-speed play of the grass court.
