Which Czech player beat Rafael Nadal in the 2015 Australian Open quarterfinals?

Tomáš Berdych defeated Rafael Nadal in the 2015 Australian Open quarterfinals.

Berdych, the Czech Republic’s seventh seed, beat third-seeded Nadal 6–2, 6–0, 7–6(7–5) at Melbourne Park. The straight-sets victory ended Nadal’s run in the tournament and sent Berdych into the semifinals, where he lost to eventual champion Novak Djokovic.

The result was notable because Nadal had dominated their earlier rivalry, especially on clay. Berdych used aggressive first-strike tennis, a powerful serve, and flat groundstrokes to prevent Nadal from settling into his usual patterns. The second set was particularly lopsided: Nadal did not win a game.

This match is sometimes confused with Nadal’s other Australian Open defeats. Stan Wawrinka beat him in the 2014 final, while Novak Djokovic defeated him in the 2012 final. In 2015, the Czech opponent was Berdych, not Lukáš Rosol, Jiří Veselý, or Radek Štěpánek.
