Three-time Australian Open finalist Murray ended the run of Robert, wasting match points in the third set and smashing his racket after the tiebreaker before advancing 6-1, 6-2, 7-6 (6), 6-2.

“He’s a fun player to watch, but not a fun player to play,” Murray said of Robert’s assortment of drop shots and deft groundstrokes.

The racket smashing was pure frustration.

“Losing that set was frustrating because it obviously means you’re out there another 30, 40 minutes at least, when I would preferably had been in the locker room,” Murray said. “My racket bit the dust. Unfortunate for it.”

Murray said he’s expecting a tough match against Federer, regardless of the Swiss player’s recent drop in the rankings that has seen him seeded sixth here.

“I think last year you could see at periods he was struggling with his back,” Murray said. “And if he’s fully fit, I’ve said all along, he’s always going to be there or thereabouts in the majors, and he’ll give himself opportunities to win more because he’s that good.”

Federer lost to Murray in the semifinals last year in five sets after beating Tsonga in five in the quarterfinals.

“It’s the same draw just one round earlier for me,” Federer said. “I’m happy this time I didn’t play five sets.”

On Tuesday, the first of the quarterfinals begin when Ivanovic plays Eugenie Bouchard and two-time Australian Open finalist Li Na takes on Flavia Pennetta.

In men’s quarterfinals, three-time defending champion Novak Djokovic plays Stanislas Wawrinka and No. 3 David Ferrer takes on No. 7 Tomas Berdych.
