Roger Federer is just three matches away from the No. 1 ranking. He can reclaim the top spot in Rotterdam—surpassing Andre Agassi as the oldest-ever men's No. 1—by making the semifinals. 

Here is the 36-year-old's most likely path to the top:

Round 1: Ruben Bemelmans 

While this is the best-possible first round for Federer, 30-year-old Bemelmans could be dangerous since the two have never played each other. Let's not forget that it was a qualifier, Evgeny Donskoy, who shocked Federer in Dubai last year.

Round of 16: Philipp Kohlschreiber

Federer is 12-0 for his career against world No. 36 Kohlschreiber. The 34-year-old German outlasted Karen Khachanov in a third-set tiebreaker in his first round. Given Federer's record and fresh legs, he probably won't have too much to worry about. 

Quarterfinals: Robin Haase

Provided the draw held up, the last player between Federer and the top ranking was going to be Stan Wawrinka. Wawrinka has never beaten Federer on a surface that isn't clay—not that it matters though, Wawrinka was ushered out in the first round by wildcard Tallon Griekspoor.

Federer's now most-likely quarterfinal opponent is going to be Robin Haase, against whom Federer is 2-0.  

In Montreal last year, Haase had to correct the fans, who kept saying "Come on, Roger!"  

If Federer reaches the semifinals—becoming No. 1 for the first time since 2012—he'd then be projected to play Alexander Zverev in the semifinals and No. 2 seed Grigor Dimitrov for his 97th career ATP title.
