Roger Federer in line to become oldest man to hold No.1 ranking

Roger Federer could become the oldest man to hold the world No.1 one ranking after accepting a late wildcard to the ATP tournament in Rotterdam.

The 36-year-old Swiss won his sixth Australian Open title and 20th grand slam last month and reaching the semi-finals of the Rotterdam Open in Holland would return him to top spot in the ATP rankings.

He would also surpass Andre Agassi as the oldest world No.1 - the American was 33 when his sixth stint at the summit of men's tennis ended in September 2003.

Federer, who won the Rotterdam Open in 2005 and 2012, told his official website: "The tournament is special for me.

"I remember playing for the first time in 1999 as it was one of the first events where I got the chance to play at the highest level."
