Tennis: Cool Fed Haas no fear after tough tie.
ROGER FEDERER never doubted he would reach the Australian Open tennis quarter-finals - despite being taken to a deciding set by Tommy Haas.
The world No.1 looked on course for a straight sets victory after an emphatic start but the German hit back to level the match and entered the decider with all the momentum.
However, Federer showed all his class to hit 18 winners and make only six unforced errors in the final set to claim a 6-4 6-0 3-6 4-6 6-2 victory.
Federer said: "In the first two sets I played perfect tennis but after that he played pretty good.
"I'm happy with the way I played in the end and I was never too nervous. I just tried to focus on my own service and thought if I could get one break it would change the match and it did."
After securing the first set, Federer raced through the second in just 28 minutes and at 2-2 and 40-15 down Haas looked finished before winning 11 straight points.
The German served out the set and took the fourth to set up a decider but Federer took advantage of a close line call to go 3-2 ahead before closing out the game to clinch a clash with fifth seed Nikolay Davydenko.
A frustrated Haas highlighted his inability to come up with the big shots at critical times.
He said: "I thought towards 2-2 in the fifth it was very open but he took it to another level and played some awesome tennis."
Russian Davydenko battled back from two sets down to claim a 4-6 4-6 6-4 6-2 6-3 victory over Dominik Hrbaty of Slovakia.
