Newport, Rhode Island :American Mardy Fish beat Frank Dancevic of Canada 6-7 (8/6) 6-4, 6-4 to reach semi-finals at the Hall of Fame Tennis Championships on Friday.
Fish, the fifth seed, reached his fifth ATP semi. He'll play Richard Bloomfield of Great Britain, a 5-7, 7-6 (7/3), 7-5 winner over 18-year-old Ryan Harrison in the grass court event.
Qualifier Bloomfield will be making his first ATP semi-final appearance. He was ranked 552 in the world.
The Briton's first-round win over Christophe Rochus was being scrutinized by tennis officials after online gambling exchange Betfair reported that the match attracted unusual action.
The 28-year-old Fish, who is ranked 79th, had knee surgery in September.
"I feel fine physically. When I had the knee injury I was hurting and I was too heavy," he said. "I worked extremely hard with it - harder than anything I have my whole life. The results are showing."
Dancevic, playing just his second tournament of the year after being sidelined by back surgery, said the long match wore him down.
"I felt the heat a little bit in the third set," he said.
