ROTTERDAM – Roger Federer celebrated becoming the oldest man to reach the world number one ranking by making the Rotterdam Open final on Saturday with a 6-3, 7-6 (7/3) victory over Italy's Andreas Seppi.
The 36-year-old Federer racked up his 14th win from 15 matches with 33-year-old Seppi, the world number 81 who had enjoyed a memorable week by reaching the semi-finals as a 'lucky loser'.
Top-seeded Federer will face Grigor Dimitrov in Sunday's final.
Dimitrov, the second seed, advanced to the semi-finals when Belgian opponent David Goffin was forced to retire after injuring his eye when the ball flew off his own racquet.
Dimitrov was leading 6-3, 0-1 at the time.
