Roger Federer, Novak Djokovic and Simona Halep made quick work of their rain-delayed matches Friday afternoon and advanced to the quarterfinals of the Western & Southern Open in Mason, Ohio, facing the daunting challenge of playing a few hours later in extremely humid conditions.
Several days of rain turned the quarterfinals into an endurance test. Six men’s and three women’s singles matches were held over from Thursday because of rain.
Federer — the top player left in the men’s bracket after No. 1 Rafael Nadal withdrew to get some rest — needed only 72 minutes to beat Leonardo Mayer 6-1, 7-6 (6).
