“To really break a barrier, one young player has to win a Slam," Dominic Thiem said following his four-set triumph over Rafael Nadal. Thiem had defeated the Spaniard four times prior, but never at the Grand Slam level and never on hard courts.

Alexander Zverev's 1-6, 6-3, 6-4, 6-2 win over Stan Wawrinka provided a bit of relief, after carrying an overwhelming amount of expectations on his shoulder. "This is a Grand Slam, and this is where you're supposed to play your best tennis and I’m doing that," Zverev said. He'll face Thiem for a spot in the final.

Zverev's girlfriend Brenda Patea joined the player box alongside the German's father/coach on Wednesday. As would be expected, she seemed tense during Zverev's quarterfinal clash against Wawrinka, but once Zverev sealed the deal she was all smiles.

"I gave myself an opportunity until the last point, so I'm happy for that," Nadal said in his post-match press conference. The Spaniard faced many questions concerning his performance level and frustration on the court, but Nadal had nothing negative to say about his game or Thiem.

Aussie duo John-Patrick Smith and Astra Sharma rallied their way back to defeat Lukasz Kubot and Iga Swiatek, 3-6, 7-6 (4), 10-3. The hometown duo will next face 2019 US Open champions Jamie Murray and Bethanie Mattek-Sands for a spot in the Aussie Open final.
