The 2005 WTA Tour was the elite professional tennis circuit organized by the Women's Tennis Association (WTA) for the 2005 tennis season. The 2005 WTA Tour included the four Grand Slam tournaments, the WTA Tour Championships and the WTA Tier I, Tier II, Tier III, Tier IV and Tier V events. ITF tournaments were not part of the WTA Tour, although they award points for the WTA World Ranking. Season summary Singles Going into 2005, Lindsay Davenport was holding the No. 1 ranking and therefore was the top seed at the year's first Grand Slam, the Australian Open. She reached the final for the first time since she won the event in 2000, coming back against Alicia Molik in the quarterfinals and Nathalie Dechy in the semifinals. Molik had a successful warm-up by winning the tournament in Sydney. Meanwhile, Serena Williams came through in the bottom half, beating Amélie Mauresmo and Maria Sharapova. In the final, Williams won her seventh Grand Slam title, and first since Wimbledon 2003. Justine Henin-Hardenne and Kim Clijsters both continued to struggle with injuries and skipped the event. The following week, Sharapova won the event in Tokyo, beating Davenport in the final. Moving into February, Mauresmo proved strong, winning in Antwerp and reaching the Paris final before losing to Dinara Safina. Sharapova also won the event in Doha, with Davenport winning in Dubai. Molik reached the semifinals of Antwerp and the final of Doha to continue her strong start to the season. Clijsters returned to competition in Antwerp, losing to Venus Williams. Clijsters then won 14 straight matches to take back-to-back titles in Indian Wells and Miami. In the former, she beat Davenport (who had defeated Maria Sharapova 6–0, 6–0 in the semi-finals) in the final. In the latter, she beat Sharapova in the final. Clijsters was only the second woman to achieve the feat of winning both tournaments, after Steffi Graf in 1996. Henin-Hardenne returned to competitive tennis in Miami, where she lost to Sharapova, but she then went on to dominate the clay season, winning events in Charleston, Warsaw and Berlin and building a 17-match winning streak. In the other big clay tournament in Rome, Mauresmo came out as the champion. Also enjoying good results in the clay season were Nadia Petrova, who reached the final of Berlin and the semifinals of Amelia Island and Patty Schnyder, who reached the semifinals of Berlin
