World No. 1, Roger Federer celebrated becoming the oldest man to reach the world number one by making the Rotterdam Open final on Saturday with a 6-3, 7-6 (7/3) victory over Italy's Andreas Seppi despite losing sleep watching early-morning coverage of the Winter Olympics. The 36-year-old Federer wipeout up his 14th win from 15 matches with 33-year-old Seppi, the world number 81 who had enjoyed a memorable week in the Dutch port city 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.

Federer said that despite not getting much sleep due to the excitement of his latest achievement and draining more energy by watching the Pyeongchang Winter Olympics in the pre-dawn hours, he expects to be fighting fit for his Sunday showdown which could result in a 97th career trophy. The two-time Rotterdam champion, who guaranteed a return to the world top spot by seeing off Robin Haase in the quarter-finals on Friday, added that he will be ready to go for his first afternoon match of the week after playing the night showcase slots.
