- No 2 seed books spot in last four with 7-6(1), 7-6(0), 2-6, 6-1 win
- German to face Novak Djokovic or Carlos Alcaraz in semi-final
Alexander Zverev has survived an extraordinary meltdown to sink Tommy Paul in four sets and charge into the Australian Open semi-finals.
Second-seeded Zverev, chasing an elusive grand slam title, was almost knocked down by, of all things, a feather before he steadied to prevail 7-6 (1), 7-6 (0), 2-6, 6-1. Zverev will next face either world No 3 Carlos Alcaraz or 10-time champion Novak Djokovic, who play on Tuesday night, in his third Melbourne Park semi-final.
