LONDON -- The 2003 and 2004 tennis masters cups will be staged at the Westside Tennis Club in Houston, Texas, the Masters Cup Committee said at Wimbledon on Saturday.

The cup is the season-ending men's tournament contested by the world's top eight players and is co-owned by the ATP, the Grand Slams and the International Tennis Federation (ITF).

For the first time the year-ending doubles championship will also be staged with the elite men's event.

"We'll be putting the year end doubles championship together with the singles and are delighted to be back in the United States for the event," ATP chief executive officer Mark Miles said at Wimbledon on Saturday.

The inaugural tournament in 2000, won by Brazil's Gustavo Kuerten, was held in Lisbon, while Lleyton Hewitt blasted through the draw to win the 2001 event staged in Sydney, Reuters reported.

This year's competition will be in Shanghai from 11-17 November.

The tournament replaced the ATP world championship and the Grand Slam cup which was held from 1990 till 1999.
