Why Nadal lost in Aus Open?

Dominic Thiem ended six years of Grand Slam frustration against Spaniard Rafael Nadal on Wednesday with a seismic 7-6(3), 7-6(4), 4-6, 7-6(6) upset that booked his maiden Australian Open semi-final spot.

After pulling off a nerve-shredding win that quashed doubts about his prowess on hard courts, the 26-year-old Austrian will face Alexander Zverev for a place in the final, a match-up scarcely imaginable at the start of the tournament.

Fifth seed Thiem will head into Friday’s clash against the young German brimming with confidence, having ended top seed Nadal’s bid for a record-equalling 20th Grand Slam title.
