Three-time defending champion Novak Djokovic cruised into the third round of the Australian Open with a 6-0, 6-4, 6-4 victory Wednesday afternoon over Argentina's Leonardo Mayer.

Djokovic was focused from the start, no doubt eager to avoid a long match in brutally hot conditions on Rod Laver Arena.

Mayer's serve posed no threat early on to the Serbian world No. 2, who had a perfect conversion rate on break points en route to a first-set "bagel." For the set, the Argentine won just four of his 17 service points.

The world No. 98 improved his serve in the second set and made the score more respectable, but he made errors when hitting for the lines and the Serbian took advantage to take the set 6-4 and grab a commanding lead in the contest.

Djokovic's superiority was evident once again in the third set, which he won by an identical 6-4 score line.

"The conditions were not easy for both my opponent and myself. You know, I started the match really, really good. I was set and a break up only after, you know, 40, 45 minutes," the four-time Australian Open winner said in the post-match press conference.

"As you said, you don't want to spend too much time in the heat. You want to try to win as quick as possible. You know, he started to play better as the match progressed, in the second part, especially in the third set. But, you know, I felt like I was serving well and I was in the control."

Next up for Djokovic in the third round will be Uzbekistan's Denis Istomin, a 7-6 (7-3), 4-6, 6-1, 6-4 winner over 30th-seeded Russian Dmitry Tursunov.

In other action Wednesday in the men's draw, third-seeded Spaniard David Ferrer pulled away in the third and fourth sets for a 7-6 (7-2), 5-7, 6-0, 6-3 win over Frenchman Adrian Mannarino.

Czech Tomas Berdych, the No. 7 seed, also advanced comfortably to the third round with a 6-4, 6-1, 6-3 win over Frenchman Kenny De Schepper.

In women's action on Wednesday, top-seeded Serena Williams of the United States trounced Serbian Vesna Dolonc 6-1, 6-2. EFE
