The life of Elena Baltacha, who died of cancer last month, was celebrated at Wimbledon as a pupil from her academy took part in the ceremonial coin toss.
Elle Robus-Miller, nine, joined womens' champion Marion Bartoli on Centre Court before Tuesday's opener between Sabine Lisicki and Julia Glushko.
The Elena Baltacha Academy of Tennis was set up to give children from all backgrounds the chance to play tennis.
Baltacha was British number one for nearly three years and retired in 2013.
"While she was still playing tennis, when most players want to go home to rest, Elena set up this academy to help kids to play tennis," said nine-time Wimbledon champion Martina Navratilova.
GB Fed Cup captain Judy Murray added: "It's not just in this country but all around the men's and women's circuit, people have been raising money to try and keep the academy going for many years to come."
Wimbledon are selling yellow "Rally for Bally" wristbands to raise money for Baltacha's academy.
White wristbands, produced specially for Wimbledon by British number two Laura Robson, were distributed among the players, keeping in line with the Championships' dress-code.
Traditionally, the ladies' singles champion opens play on the second day of Wimbledon, but France's Bartoli will not be defending her title following her retirement in August.
