Indian tennis ace Sania Mirza will spearhead the Asia-Pacific challenge in the World Team Challenge tournament in Hong Kong in 2009.

The January 7-10 tournament, a new concept and warm-up competition for the Australian Open, will feature four teams representing Europe, Russia, the Americas and Asia-Pacific.

Each team will be represented by three players who would compete in both singles and doubles.

There will be a semi-final draw for the teams, with each tie consisting of singles and doubles rubbers. The two teams which scores the most number of wins overall will progress to the final.

World number one Jelena Jankovic will lead Team Europe, Venus Williams will head the Americas, while Maria Sharapova will be leading Russia. The rest of the field will be announced later.

The tournament will replace the JB Group Classic exhibition, which is traditionally a warm-up event for women in the run up to the first Grand Slam of the season in Melbourne in January.
