Fed faces Seppi in Halle final

Roger Federer reached the Halle grass-court final for the 10th time after beating giant Croatian Ivo Karlovic 7-6 (7/3), 7-6 (7/4) in Saturday's semifinals.

The Swiss, who has won the title seven times, will go on to face Italy's Andreas Seppi, who advanced at the expense of Kei Nishikori after the Japanese world number five retired injured when trailing 4-1 in the first set.

World number two and top seed Federer needed two tie-breaks to claim a 13th win in 14 meetings with Karlovic.

"It is always difficult to play against Ivo but the important thing was that I remained calm," Federer said.
