With Roger Federer unable to play in Cincinnati due to a back injury and Andy Murray also out of the event, Rafael Nadal is guaranteed a return to No. 1 next Monday, regardless of outcome at the tournament.
Nadal has spent 141 weeks at the top spot but hasn’t been No. 1 since July 6, 2014.
Rafa first reached No. 1 on August 18, 2008 at the age of 22, almost 9 years ago to the day.
Rafa will also be the top seed at the US Open for the first time since 2010, and first time at a Grand Slam since the 2014 French Open.
The 31-year-old Nadal is 47-8 on the season with four titles including a 10th French Open. He won Cincinnati in 2013.
