Andy Murray was among a number of players to stand on court and pay tribute to former British number one Elena Baltacha with a minute's silence at the Mutua Madrid Open on Monday.
A number of high-profile players, including Murray and his brother Jamie, observed the tribute on Centre Court at the Manolo Santana Stadium before the start of the tournament's night session.
Baltacha was diagnosed with the illness in January, just two months after retiring from tennis and only weeks after she married her long-time coach Nino Severino.
"We are heartbroken beyond words at the loss of our beautiful, talented and determined Bally," Severino said in a statement released by her family.
"She was an amazing person and she touched so many people with her inspirational spirit, her warmth and her kindness."
The statement said Baltacha died peacefully at home.
