The Japanese will go up against Wawrinka on Thursday for a place in the quarter-finals. The winner could play Rafael Nadal. Wawrinka beat Argentina’s Guido Pella 6-3, 6-4, with a break in each set proving enough for the three-time Grand Slam champion. Nishikori has lost his last two meetings with Wawrinka, including a three-set defeat in Rotterdam in February, when his Swiss opponent went on to reach his first final since undergoing knee surgery in 2017. The pair have reached 12 grand slam semi-finals between them. Nishikori’s compatriot and world number one Naomi Osaka is through to the quarter-finals of the women’s tournament for the first time after she eased past Belarusian Aliaksandra Sasnovich 6-2, 6-3. Osaka pulled out of the semi-finals in Stuttgart last month with an abdominal injury but has said she is no longer feeling discomfort during matches. “The ab injury was always sort of in the back of my mind, but that was more in the first round and now I feel fine, so that’s great. I’m at a really good place right now. I feel like I’m having fun playing tennis again which is always a good thing for me. I always play well if I have that mentality,” Osaka said. In the last eight, the two-time major champion will face either Switzerland’s Belinda Bencic who beat Ukraine’s Kateryna Kozlova 6-0, 6-2. A potential semi-final foe for Osaka is world number three Simona Halep, who annihilated Slovakian Viktoria Kuzmova 6-0, 6-0 in 44 minutes. Halep is chasing her third Madrid title after winning the tournament in 2016 and 2017.
