Rafael Nadal fended off his fellow Spaniard Albert Ramos-Vinolas as the world number one elect reached the quarter-finals of the Western & Southern Open on Friday.
He teed up a clash with Nick Kyrgios for later in the day after coming through the rain-delayed clash with Ramos-Vinolas a 7-6 (7/1) 6-2 winner.
Nadal will go top of the world rankings on Monday, overtaking Andy Murray, and could hit the summit with a fifth title of the year.
Kyrgios, like Nadal, had been due to play his third-round match on Thursday, but it too carried over into Friday because of the wet weather.
There was a scare for Kyrgios as he dropped the opening set to big-serving Croatian veteran Ivo Karlovic, but the Australian scrambled to retrieve the match and take a 4-6 7-6 (8/6) 6-3 win.
