Relieved Federer through, Jankovic falls at Open

By Ossian Shine

MELBOURNE (Reuters) - A roar of relief marked Roger Federer's comeback from two sets down at the Australian Open on Sunday while women's world number one Jelena Jankovic was mute and ineffectual in a fourth-round defeat.

The whole of Melbourne Park shook with an explosion of home-town roars, however, when Yugoslav-born Australian wildcard Jelena Dokic buried years of personal pain to reach the quarter-finals of the first grand slam of the year.

The 25-year-old, whose split from domineering father Damir and subsequent struggle with severe depression and injuries was played out in front of the world's media, wiped tears from her eyes after her 7-5 5-7 8-6 win over Russian Alisa Kleybanova.

"I'm just really fighting," Dokic said. "I'm really determined and fighting. That's sometimes what keeps it going.

"I think (my coach) might have a few drinks tonight. I think I might as well," she smiled.

Swiss Federer dug himself out of deep trouble against Czech Tomas Berdych, prevailing 4-6 6-7 6-4 6-4 6-2 to keep alive his hopes of a record-equaling 14th grand slam crown.

WEATHER STORM

"I fought as hard as I could, tried to weather the storm... he pushed me to the limit," the second seed smiled courtside afterwards.

"I enjoy those kind of fights because they don't happen very often. I am still in great shape, feel like I could play another couple of sets so that's a good sign."

There were no good signs for Jankovic who was blown off court by French typhoon Marion Bartoli 6-1 6-4.

"When I'm on the top of my game it's very hard to beat me, because you really have to kind of spill blood if you want to win the match," Jankovic mused afterwards.

"But at the moment, I'm not there yet. I still need to get better, to improve, be much, much tougher out there. Nobody likes to lose. Today was a tough day for me."

Jankovic's tough day was a jubilant one for Bartoli.

"I knew I could beat Jelena on a good day, it was just a matter of executing," she told reporters.

Bartoli next plays Vera Zvonareva after the seventh seed beat her 10th-seeded fellow Russian Nadia Petrova 7-5 6-4.
