Wimbledon glance

Tuesday lookahead: Seven-time champion Serena Williams will meet Camila Giorgi of Italy in a quarterfinal match. Williams has won all three of their prior meetings, with the most recent coming in the first round of the 2016 Australian Open. With the top 10 women having all been eliminated, No. 11 Angela Kerber is the highest-seeded player left in the tournament, and she will face 14th-seeded Daria Kasatkina. Kerber beat the Russian two weeks ago in a third-set tiebreaker on the grass courts of Eastbourne, tying their head-to-head record at 3-3. The only fourth-round match that wasn’t completed on Monday — fifth-seeded Juan Martin del Potro against Frenchman Gilles Simon — will be played to a finish. Del Potro led 7-6 (1), 7-6 (5), 5-7 when play was suspended because of darkness.

Tuesday forecast: Partly cloudy, with a high of 74 degrees. harder,” Mannarino said. “This is what is not easy to handle.”

He showed up wearing a plain white T-shirt, bereft of any obvious sponsor’s logos, looking like someone out for a casual hitting session in a public park.

It took Mannarino so much toil and trouble to win one game, saving four break points to hold to begin the second set. He was able to tread water until 5-all, when Federer returned a 123 mph serve, quickly gained control of a baseline exchange, then hopped and screamed, “Come on!” as a backhand flew long for the break. Federer also broke, then held to end the match.

“I think,” Federer said when it was over, “I can be very pleased.”
