Andy Murray disappointed with Australian Open draw Federer, meanwhile, will play Jo-Wilfried Tsonga in tomorrow's night match starting at 7.30pm. As this will be his fourth successive night match, he will be well adapted to the conditions, which do change significantly depending on variables like temperature and humidity. The concern for Murray is that it may take him a few games to find his touch and timing on the court, just as it did when he went from a second-round match on Hisense Arena - Melbourne Park's second-string show-court - to a third round on Rod Laver Arena against Ricardis Berankis. Berankis was able to disconcert Murray early on with his fast feet and flat ball-striking, but as the world No. 110, this was never going to be more than a fleeting challenge. If Federer should leap out quickly into the lead, however, that is a very different matter. He is known to be the best front-runner in the business, and will take some catching. Speaking about the potential disadvantage, Murray said: "Once you get to the semi-finals or finals here, both matches will be in the evening. Ideally it would be nice to get a [quarter-final] match in the evening but if not you just get on with it. Sometimes the schedule works well for you and sometimes it doesn't work out perfectly. I've had scenarios like at the US Open where it worked in my favour. Wimbledon didn't necessarily work in my favour this year, or last year, and the first US Open final I played, it didn't work in my favour. But you don't dictate the schedule, you just try and play and deal with everything as best you can. Federer has won his last three meetings against Tsonga and there were signs on Monday night that his attention is already turning to that possible semi-final against Murray. Asked by TV presenter Jim Courier about the importance of fitness, he replied that "Muscle pain is part of the business - maybe I felt a little bit at the Olympics, but then again it's in the details and for instance Murray just played too good for me." Given that the Olympic final was their last meeting over five sets, and that Murray won it with unusual comprehensiveness, it was interesting that Federer should have chosen this moment to mention that he had been carrying a niggle.
