process. Her greatest success was Scottsdale 2003. Beating Lindsay Davenport in the second round, she went on to defeat Eleni Daniilidou to progress to the semifinals. Scheduling problems forced both the semifinals and finals matches - for both singles and doubles - to be played on the Sunday of the tournament. Thus in a single day, Sugiyama managed to save a matchpoint in the semifinals against Alexandra Stevenson, rally from a set down to defeat doubles partner Kim Clijsters in the final, and then secure victories in both doubles matches to raise both trophies. The year 2003 proved to be her best year ever, pushing Serena Williams to the limit at Roland Garros and reaching the round of 16 in Wimbledon and US Open where her fourth round loss to Francesca Schiavone at Flushing Meadows was rather controversial. She finished the year ranked tenth, having defeated world No. 1, Justine Henin, in the round robin section of the season-ending championships.

Sugiyama also reached the final in doubles with Hantuchová, losing to Virginia Ruano-Pascual and Conchita Martínez. She broke her Grand Slam "curse", reaching the third round before losing to Clijsters, the eventual champion. That year, Ai had better results in doubles than in singles. Partnering with Elena Dementieva, she reached the finals of her first tournament, Sydney, losing to Bryanne Stewart and Samantha Stosur. They reached the round of 16 at the Australian Open. She entered a few tournaments with Anastasia Myskina and Elena Likhovtseva, but with poor results. In Berlin, she played again with Daniela Hantuchová, reaching the semifinal, losing to Black and Huber. At the French, they lost to Birnerová and Vanc in the second round. They won their next tournament, in Birmingham over Daniilidou and Russel. At Wimbledon, Hantuchová and Sugiyama reached the quarterfinal, losing to eventual champions Black and Huber. At the Canadian Open in Toronto, they lost the semifinal to eventual
