Roger Federer fights back to reach Gerry Weber Open final

Federer,five-times champion at Halle,will play either Frenchman Richard Gasquet or Russian Mikhail Youzhny who contest the other semi-final later on Saturday.

8220;I felt good out there and as I had predicted it was a tough match,8221; Federer said in a courtside interview.

8220;I have not won a title this year,twice I have lost here in the final in the past years. It will not be easy but I am really looking forward to it.8221;

Federer8217;s unusually erratic forehand earned 35-year-old Haas his first break points at 3-2 and another long crosscourt forehand by the Swiss gave the world number 11 a two-game cushion.

Haas,whose 2012 final win over Federer was his first in 10 years against him,saved two break points at 5-2 to serve out the set when Federer pushed another forehand long.

The tables were turned in the second set with Federer racing to a 3-0 lead after breaking Haas,whose injury-free season has seen him win in Munich and reach the French Open last eight,with a much more aggressive game.

After drawing level,Federer kept up the pressure to earn yet another break when Haas double-faulted twice in a row to go 3-1 up and he clinch victory on his second match point.
