Roger Federer has overcome a poor start to brush aside Tomas Berdych in straight sets to make another Australian Open semi-final at Melbourne Park.
The 7-6 (7/1), 6-3, 6-4 victory put the superstar a step closer to his 20th grand slam title, setting up a match against unseeded South Korean Hyeon Chung, a victor earlier in the day over American Tennys Sandgren, for a place in the final.
The opening set essentially turned on a few moments late on, where the 19-time major title winner found his form in a hurry to come from behind and deliver a devastating psychological blow to his opponent.
Berdych — whose last win over Federer had come at the US Open in 2012 — had started out looking far sharper. He broke in the second game, and was leading 5-3 on his serve, with a chance to go a set up.
The Swiss master had two break points in the ninth game, but he was still visibly tense.
