- World No 1 drops a set to American but wins 7-6 (3), 4-6, 6-2, 6-3
- Djokovic has always won Australian title after reaching last four
Novak Djokovic fought off a strong challenge from Taylor Fritz to reach the Australian Open semi-finals for the 11th time.
The world No 1 has never lost in Melbourne once he has made it beyond the last eight, and there is no doubt how much he wants a 25th grand-slam title.
