LONDON (Reuters) - Roger Federer chalked up another monumental milestone to reach the Wimbledon semi-finals on Wednesday, recovering to beat Japan's Kei Nishikori in four sets and become the first man to record a century of singles wins at any Grand Slam.

Federer, who won 4-6 6-1 6-4 6-4 and now faces Rafa Nadal in a mouthwatering contest, was so poor in the first set that the eighth-seeded Nishikori may have felt the 37-year-old Swiss's advancing years had finally caught up with him.
