Roger Federer 4-6 7-6(2) 6-4 4-6 *5-5 John Millman: Everyone in Rod Laver Arena is feeling the nerves right now, but Millman showed his mettle by coming through another service game with everything on the line. This time, a couple of sloppy errors reduced Millman’s 30-0 lead to 30-30. Instead of panicking, the Aussie calmly pounded a point-ending forehand down the line before finding an unreturned serve to hold. 1.21pm GMT
Roger Federer 4-6 7-6(2) 6-4 4-6 5-4* John Millman: The nerves from Federer are so palpable and this time they affected his serve: he threw in two double faults and found himself at the precarious score of 30-30. However, the Swiss steadied himself with two good first serves to keep himself ahead. He stands one game away from crawling over the line.
