Tennis stars past and present will take part in a fundraising event at Eastbourne next month in memory of Elena Baltacha.
The former British No. 1 has died of liver cancer, aged 30.
Baltacha was a stalwart of the Aegon International at Devonshire Park, played the week before Wimbledon.
Andy Murray, Martina Navratilova, Tim Henman, Greg Rusedski, Jamie Murray and Heather Watson are among the players who have agreed to take part in a fundraising event, The Rally Against Cancer - Rally For Bally, which will now be held in her memory on June 15.
The traditional mixed doubles exhibition matches at Eastbourne, at the Aegon Championships at Queen's Club and the Aegon Classic in Birmingham will raise money for the Royal Marsden national cancer charity and Elena Baltacha Foundation.
Baltacha almost pulled off a first round surprise as a wild card at Eastbourne last year, pushing Russian sixth seed Maria Kirilenko to three sets.
Baltacha, a regular at the Sussex showpiece since 2001, reached the quarter-finals in 2010.
Eastbourne-based British colleague Johanna Konta tweeted: "Words can't describe..you inspired and humbled everything you touched. I know you're in heaven because that's where angels belong.
"Rest in peace Bally. You will never be forgotten."
