Andy Murray to face Mardy Fish in midday heat again
Cincinnati Masters - Murray v Fish Coverage: Live on Sky Sports at 1700 BST, live text commentary on BBC Sport website and updates on BBC Radio 5 live
Murray will try to win his first Grand Slam title at the US Open next month
Andy Murray will have to endure the fierce afternoon heat in Cincinnati once again when he takes on Mardy Fish in the quarter-finals on Friday.
The Briton struggled in temperatures of over 30C as he battled past Ernests Gulbis in three sets on Thursday.
But Murray's request for a later start on Friday was unsuccessful and he takes on Fish at 12pm local time (1700 BST).
Andy Roddick and Roger Federer are also in action, with Rafael Nadal playing Marcos Baghdatis in the night match.
Murray is on a seven-match winning streak after beating Nadal and Federer on his way to taking the Toronto title last week, and that run appeared to be taking its toll against Gulbis on Thursday.
"Every match since the first one in Toronto has been between 12pm and 3pm and it was really warm on the court today," he told BBC Radio 5 live after the match.
"I got a bit burnt on the face and also, because of the exercise, a bit dehydrated as well, which probably doesn't help. I'll try and make sure I recover as best as possible for tomorrow."
However, the Scot's hopes of getting a helping hand from the tournament officials were dashed as he was scheduled for the opening match on Friday.
"I think it's fair to request (a later start) after the last eight or nine days," he said before hearing the order of play, "but you never know what's gong to happen. It would be nice to play at 5pm or 6pm, that would help me out a little bit."
And despite the US Open starting on 30 August, Murray insisted that he was keen to continue his winning run, saying, "You want to try and wins as many matches as possible".
