Roger Federer’s withdrawal means Nadal will replace Andy Murray as world number one

Rafael Nadal moved into the Cincinnati Open quarter-finals with victory over fellow Spaniard Albert Ramos.

Both players were wearing black ribbons on their shirts in memory of the victims of the attacks that took place in Barcelona and Cambrils on Thursday.

Nadal, 31, won 7-6 (7-1) 6-2 to set up a quarter-final tie with Australia’s Nick Kyrgrios.

Kyrgrios and Nadal will play their quarter-final match later on Friday (not before 02:00 BST on Saturday).

Roger Federer’s withdrawal from the tournament means Nadal will return to world number one for the first time since July 2014, taking over from Andy Murray who is also injured.

Meanwhile, Karolina Pliskova solidified her world number one ranking by beating Camila Giorgi and Caroline Wozniacki.

The Czech defending champion beat Italian qualifier Giorgi 6-3 4-6 6-0 in their third-round match, before defeating world number five Wozniacki of Denmark 6-2 6-4 in a schedule reshuffled after Thursday’s rain delays.

The 25-year-old now faces Spain’s Garbine Muguruza in the last four.

Wimbledon champion Muguruza beat Russian eighth seed Svetlana Kuznetsova 6-2 5-7 7-5 and also made a special tribute to victims of the attacks in her country’s Catalonia region.
