Federer survives massive scare in Melbourne

By Simon Cambers

MELBOURNE (Reuters) - Champion Roger Federer survived a massive scare before scrambling to a 6-7 7-6 5-7 6-1 10-8 third-round victory over Serb Janko Tipsarevic at the Australian Open on Saturday.

With the world number one and top seed strangely off-color, a huge shock looked a real possibility when world number 49 Tipsarevic led by two sets to one but the Swiss came through a tense final set to take his place in the last 16.

"What a great battle. Fair play, he's a nice guy -- pity somebody has to win, wish we could have draws sometimes too," Federer said in a courtside interview.

"This is where you get grey hair early in life. Pity for him, but what a great victory for me."

A sluggish Federer lost the first set, having served for it at 5-3. It was the first set he had dropped at the Australian Open since 2006.

Federer hit back to level the match by cruising through the second set tiebreak, only to lose the third after holding two set points on the Tipsarevic serve in the 10th game.

But Federer, chasing his 13th grand slam title, leveled and in a tense final set, broke in the 17th game and served out to line up a clash with Czech 13th seed Tomas Berdych or Juan Monaco, the 21st seed from Argentina.

Having looked supremely confident in his opening two matches, Federer was expected to breeze past Tipsarevic, who had won only two matches in three visits to the Australian Open until this year.
