Federer trailed early on, but 19th seed Berdych faltered when serving for the first set at 5-3 when Federer was infuriated by the malfunction of the Hawkeye video replay. Berdych had one set point which Federer saved with a sweetly-struck backhand and another backhand went past him to give the Swiss the break back.He's done it again, Roger Federer is through to the #AusOpen semi-finals.

Second seed Federer turned on the style in the tiebreak, allowing Berdych a solitary point, and then wrapped up the second set with a single break of serve. Berdych could have thrown in the towel when he fell behind in the third set, but kept Federer on his toes by breaking back.
