For years, Roger Federer had been the leader of the pack with 528 weeks in the top-2, becoming the first player with at least 200 weeks at both no. 1 and no. 2 positions. For the first time since 2002, Federer couldn't enter the top-2 throughout 2019, allowing Rafael Nadal to catch him and become the second player with 528 weeks in the top-2, set to pass Roger and hold the record by himself on Monday.
Nadal will become world no. 1 again on Monday, moving in front of Novak Djokovic and battling with the Serb for the year-end no. 1 spot in Paris and London. After incredible progress in the last couple of years, Nadal became world no.
2 for the first time in 2005 after conquering the title in Stuttgart, claiming no less than 11 ATP titles that year as a teenager and standing as the closest rival of Roger Federer who was miles in front of all the opponents in those years.
In 2006 and 2007, Nadal accumulated more than 100 wees as world no. 2 before finally passing Roger in August 2008 when he became world no. 1 for the first time, ready to embrace his eighth stint on the ATP throne on Monday and to finish the season there if he delivers a few more triumphs in Paris and London.
Nadal's first stint in the top-2 had lasted for four years, never leaving the top-10 since April 2005 and enjoying another long run in the top-2 that has been on for more than two years after entering there following the title at Roland Garros.
If he defends 1200 points in Melbourne in January, Nadal should stay in the top-2 for many more months next year, not enjoying the most successful clay-court swing in the first couple of tournaments and having a chance to earn the points there and add more fuel to his ranking milestones that stand second to none in many aspects.
