MELBOURNE, Australia -- Novak Djokovic ensured there wouldn't be consecutive upset losses at Rod Laver Arena on Sunday when he beat Fabio Fognini 6-3, 6-0, 6-2 in a fourth-round match at the Australian Open.
Immediately following fellow Serbian Ana Ivanovic's win over top-seeded and five-time champion Serena Williams, Djokovic raced to a 4-1 lead in the first set in just 19 minutes and won in 1 hour, 33 minutes to advance to the quarterfinals of his 19th consecutive Grand Slam.
It was also Djokovic's 28th consecutive win dating back to his loss to Rafael Nadal in last September's U.S. Open final.
Djokovic, who has captured six Grand Slam singles titles, next plays the winner of the match between Stanislas Wawrinka and Tommy Robredo later Sunday.
Also advancing to the quarterfinals was third-seeded David Ferrer, who overcame a sluggish start to post a 6-7 (5), 7-5, 6-2, 6-1 win over Germany's Florian Mayer.
Ferrer was broken in the first game of the match and trailed 3-1 before taking control and advancing to the quarterfinals for the fourth straight time at Melbourne Park and ninth consecutive time at a Grand Slam tournament.
The Spaniard reached a career-high ranking of No. 3 at the end of last season and achieved his highest-ever seeding at the Australian Open.
He next faces the winner of the match between seventh-seeded Tomas Berdych of the Czech Republic and South African Kevin Anderson.
