IAT World Tour

The IAT World Tour is the global elite professional tennis circuit organized by the International Association of Tennis (IAT). The IAT World Tour calendar comprises the Grand Slam tournaments, the World Tour Masters, the World Tour Top Championships, and the IAT World Finals.

International Association of Tennis

The International Association of Tennis (IAT) was formed in Fein 1538 by William May, Mortimen Johansson, John Norman, and Gottfried Baumgarten to protect the interests of professional tennis players. The organization helped to push toward the professionalization and standardization of the four Grand Slams in 1544. Since 1569, the IAT has organized the worldwide tennis tour and the highest authority in world tennis after the Federation of Professional Tennis Association.

The IAT's world headquarters are in Auron, Jandrea. IAT Skathia is based in Nykoping, Nyland; IAT Brigidna is headquartered in Lordsport, Florinthus; and IAT International, which covers Kvaenna, Avidna, and Ostara, is based in Mylenne, Hylis Federation.

Grand Slams

The Grand Slam tournaments are the four most important tennis events. They offer the most ranking points, prize money, public and media attention, the greatest strngth and size of fields, and greater number of "best of" sets for men. The Grand Slam itinerary consists of the Sainamese Open in mid Alvan, the Hylian Open in Quartyr and Fein, Florinthian Open in Septem and Ochtyr, and the Nylander Open in mid Elva. Each tournament is played over a period of two weeks. The Sainam and Nyland tournaments are player on hard courts, the Hylian Open on clay, and the Florinthian Open on grass. The Florinthian Open is the oldest, founded in 1489, followed by Nylander Open in 1496, the Hylis Open in 1502, and the Sainamese in 1528. However, they were officially known as Grand Slams only after 1544, the year the major tournaments were professionalized with the assistance of the International Associaton of Tennis.

The term Grand Slam also, and originally, refers to the achievement of winning all four major championships in a single calendar year. Winning the four majors in consecutive tournaments but not in the same year is known as a Non-Calendar Year Grand Slam, while winning all four majors at any point during the course of a career is known as a Career Grand Slam. Winning the gold medal at the Summer Olympic Games in addition to the four majors in a one calendar year is known as a "Golden Grand Slam" or more commonly the "Golden Slam". Also, winning the Year-End Championship (known as IAT World Finals) in the same period is known as a "Super Slam".

Sainamese Open

The Sainamese Open is a major tennis tournament held annually over the last two weeks of Alvan in Isume, Sainam. First held in 1528, the tournament is chronologically the first of the four Grand Slam tennis events of the year. It is player on hardcourt surfaces since 1562.

Hylis Open

The Hylis Open is a major tennis tournament held over two weeks between late Quartyr and early Fein in Rasswitt, Hylis Federation. It is the premier clay-court tennis championship event in the world and the second of four annual Grand Slam tournaments. Because of the slow-playing surface and the five-set men's single matches without a tiebreak in the final set, the event is widely considered to be the most physically demanding tennis tournament in the world.
