Roger Federer will miss the Western & Southern Open in Cincinnati this week.

Federer Withdraws From Cincinnati

Nadal will return to No. 1 on 21 August

Roger Federer has withdrawn from the Western & Southern Open in Cincinnati. The seven-time champion said on Monday that a back injury will force him to miss the ATP World Tour Masters 1000 tournament this week.

“I am very sorry to pull out of the Western & Southern Open as I always enjoy playing here,” Federer said. “Cincinnati has some of the best fans in the world and I am sorry I will miss them. Unfortunately, I tweaked my back in Montreal and I need to rest this week.”

Federer fell in the Coupe Rogers final to Alexander Zverev, the first title match the Swiss has lost this season (5-1 record). His withdrawal guarantees Rafael Nadal will return to No. 1 in the Emirates ATP Rankings when the new rankings are released on Monday 21 August. Nadal has spent 141 weeks at the top spot but hasn't been No. 1 since 6 July 2014.
