Cincinatti - Unseeded American Mardy Fish toppled world number four Andy Murray of Scotland 6-7 (7/9), 6-1, 7-6 (7/5) on Friday to reach the semifinals of the Cincinnati Masters.
Fish sealed the victory and became the first unseeded player since Lleyton Hewitt in 2007 to reach Cincinnati's final four when Murray dumped a forehand into the net to end a gruelling encounter in torrid temperatures.
Murray, who triumphed last week in Toronto, received massages on both legs during several changeovers, but was able to take a 4-2 lead in the second tie-breaker.
Fish then reeled off four straight points, the last when Murray went wide with a forehand passing attempt.
The miss had Murray belting a ball out of the court in frustration, and Fish soon advanced to a meeting with either ninth-seeded compatriot Andy Roddick or second-seeded Novak Djokovic of Serbia.
