The week behind us brought one change in the Top 10 but we could see a change at the top of the men's rankings next Monday, as Roger Federer chases world number 1 spot in Rotterdam! While we were speculating about his participation in Dubai later this month, the 36-year-old surprised everyone when he announced that he took the wild card in Rotterdam and he needs to win three matches to become world number 1 for the fourth time in his career, the first since November 2012. After he successfully defended his Australian Open crown, Roger is just 155 points behind Rafael Nadal and he couldn't miss a chance to enter Rotterdam and try to pass his great rival, needing a semi-final result to sit on the ATP throne once again, as by far the oldest world number 1 since 1973! Nadal opened his 167th week at the top and he is just three weeks shy of John McEnroe who was world number 1 for 170 weeks.
Still, the Spaniard lost the points in Melbourne after playing in the final 12 months ago and his destiny is in Roger's hands now. Of course, even if he loses the first place Nadal will have a chance to get it back in March as Roger defends 2000 points from Indian Wells and Miami, and it should be a wild chase between two tennis titans for the year-end number 1 spot that Nadal grabbed at the end of 2017.
Marin Cilic remained 3rd, far behind Nadal and Federer, and he will not improve his tally this week, deciding to skip ATP 250 tournament in Buenos Aires due to fatigue. Alexander Zverev managed to pass Grigor Dimitrov by 25 points in 4th and 5th and they will continue their battle for the ranking positions this week in Rotterdam, joining Roger in a strong field.
Nothing changed between positions 6-12, with Dominic Thiem, David Goffin, Jack Sock, Juan Martin del Potro and Pablo Carreno Busta closing the Top 10 group.
Stan Wawrinka reached the semi-final in Sofia and he gained two positions to be 13th, five points ahead of Novak Djokovic. Quito finalist Albert Ramos-Vinolas entered the Top 20 and he ousted Andy Murray from that group for the first time since April 2008, almost 10 years ago! Sofia champion Mirza Basic entered the Top 100 after gaining 52 positions while Quito champion Roberto Carballes Baena stands just in front of him, making a 31-spot progress.
Quito semi-finalist Thiago Monteiro jumped for 22 places and Sofia finalist Marius Copil also had a great week in terms of rankings, equalling his career-best position. Top 20 ranking:
