Maria Bueno, a Brazilian tennis great who won three Wimbledon singles titles and four at the U.S. Open in the 1950s and 1960s, and helped usher in modern women's tennis, has died after battling mouth cancer. She was 78.
Bueno was admitted to the Nove de Julho hospital in Sao Paulo in May. The hospital released a statement on Friday afternoon confirming her death, but declined to provide more details out of respect for her family.
"A very sad day for sports. Brazil and the world lost a true tennis legend," tweeted the International Olympic Committee, one of several sports organizations and professional tennis players to praise Bueno's contribution.
