Nadal, Federer advance at Australian Open

Former No. 1-ranked Jelena Jankovic beat Chang Kai-chen of Taiwan 6-4, 6-2

Eighth-ranked Mardy Fish became the first top 10 player on the men’s side to lose, falling 7-6 (4), 6-3, 7-6 (6) to Colombia’s Alejandro Falla.

No. 7 Tomas Berdych beat Olivier Rochus of Belgium 6-1, 6-0, 7-6 (4) and 2009 U.S. Open champion Juan Martin del Potro, No. 18 Feliciano Lopez and No. 30 Kevin Anderson also advanced.

Qualifier Lukas Lacko of Slovakia beat American Donald Young 6-3, 6-1, 3-6, 6-3 to earn a match against Nadal.

Nalbandian had several run-ins with the chair umpire during the often tense match. The Argentinian was enraged when a tournament official refused to overrule the chair umpire’s decision to decline a review of a line call late in the fifth. He later smashed his racket to the ground in disgust when he netted a backhand on match point.

“It’s ridiculous playing this kind of tournament with this kind of umpires,” Nalbandian said. “I didn’t understand in that situation, 8-all, break point.”

Ivo Karlovic of Croatia beat Carlos Berlocq of 7-6 (4), 3-6, 6-3, 6-4 and will play Federer in the third round, while 13th-seeded Alexandr Dolgopolov of Ukraine defeated Tobias Kamke of Germany 4-6, 6-1, 6-1, 3-6, 8-6.

Australian teenager Bernard Tomic beat another American Sam Querrey in the first night match on Rod Laver Arena, 3-6, 6-3, 7-6 (3), 6-3. Tomic will play Dolgopolov in the third round.

No. 21 Stanislas Wawrinka beat 2006 finalist Marcos Baghdatis of Cyprus 7-6 (3), 6-4, 5-7, 6-1.

Nadal figures he’s in strong shape to add a second Australian Open title to the one he captured in 2009, one of his 10 Grand Slam singles titles.

“I’ve been practicing well, I’ve had a very good preparation in my opinion,” Nadal said. “I’ve won two matches in straight sets with positive feelings.”
