The build-up to Wimbledon was overshadowed by scandal yesterday after Dan Evans, the British No3, confessed that he has tested positive for cocaine.
Evans has a reputation as a rule-breaker, but this offence is on another level. He faces the theoretical maximum of a four-year ban, and will be lucky to get away with anything less than two. At 27, his career must be in doubt.
It is hard to remember a comparable instance in British tennis. It's true that Greg Rusedski tested positive for the steroid nandrolone in 2004, but he later cleared his name after a tribunal ruled that he had ingested the substance inadvertently.
Rusedski offered Evans a vote of support, saying "hopefully he can clean up his life and get help," but other former players were more critical. "He has chucked his career away," said the former British No1 Andrew Castle. "A massive mistake."
John Lloyd, who had been Evans' first Davis Cup captain in 2010, said: "The bottom line is how many chances do you get? He has had so many in his career, got in trouble and then came back. At some stage, it has to change."
