Brazil's top-ranked tennis player Thomaz Bellucci has ended his partnership with Gustavo Kuerten's former coach Larri Passos.
Bellucci says they reached an agreement to part ways after a series of disappointing results. Passos was Kuerten's coach when the Brazilian won three Roland Garros titles.
Since hiring Passos about a year ago, Bellucci has won 25 matches and lost another 25, without winning a title.
The 36th-ranked player said in a statement late Wednesday that he was grateful for all that he learned from Passos but that it was better to end the partnership.
