Though he’s sitting out the clay-court season for a second consecutive season, Roger Federer has reclaimed the No. 1 ranking after Rafael Nadal fell in the quarterfinals of last week's Mutua Madrid Open.
Nadal, who won the Masters 1000 event in Madrid last year, needed to defend all of his champion’s points to hang onto the ATP tour's top spot, but those hopes were cut short by a 7-5, 6-3 loss to Dominic Thiem.
The Spaniard had won a record 50 sets in a row on clay going into that match.
And so Federer will now begin his 309th career week at No. 1. His first 308 career weeks at No. 1 came in four stints: February 2, 2004 to August 17, 2008 (237 weeks); July 6, 2009 to June 6, 2010 (48 weeks); July 9 to November 4, 2012 (17 weeks); and February 19 to April 1, 2018 (6 weeks).
The Swiss will miss the French Open for the third straight year and then make his return to the tour for the grass-court season with scheduled stops in Stuttgart, Halle and, of course, Wimbledon.
