Rafael Nadal will replace Andy Murray as the new world No. 1 next Monday (21 August) as Roger Federer has withdrawn from the Western & Southern Open in Cincinnati citing a back problem.
Our champ missed out on an opportunity to become No. 1 in Montreal when he was beaten by Denis Shapovalov.
Rafa, who has spent 141 weeks at No. 1 in his career, last held the ranking in 2014.
