Sport in brief: America's Cup rivals end their legal battle

Sailing: One of the bitterest chapters in America's Cup history has officially ended with the new and old champions agreeing to drop their legal claims against each other.

The agreement comes a month and a half after BMW Oracle Racing, owned by American software tycoon Larry Ellison, routed the defending champion Alinghi of Switzerland in Valencia, Spain. In the settlement announced yesterday, San Francisco's Golden Gate Yacht Club, which backs BMW Oracle, says it will drop its breach of fiduciary duty claim against Société Nautique de Genève, which backs Alinghi.

Canas decides to retire

Tennis: Argentina’s Guillermo Canas has announced his retirement at the age of 32 due to a persistent right wrist injury. The former world No 8 made the news public at the Sony Ericsson Open in Miami yesterday. “I wanted to be 100 per cent sure when I made the announcement,” Canas said. “I tried again at the US Open and I felt too much pain. I played two exhibitions in Argentina in December, but it was not good. My wrist just won’t let me play.”
