Andy Murray wins but Heather Watson & Laura Robson lose
Andy Murray continued his quest for an Olympic singles medal by crushing Finland's Jarkko Nieminen to reach the third round at Wimbledon.
The Scot beat Stanislas Wawrinka under the Centre Court roof on Sunday and did the same with a 6-2 6-4 win over 43rd-ranked Nieminen.
Murray next plays Cypriot Marcos Baghdatis, who he beat in the third round of Wimbledon last month.
Heather Watson lost to Maria Kirilenko and Laura Robson to Maria Sharapova.
British number one Watson was beaten 6-3 6-2 after Robson went down 7-6 (7-5) 6-3 earlier in the day.
"It was tough today," said an emotional Watson. "Maria played really well - she doesn't give anything away. She definitely made me play that extra ball. I wasn't aggressive enough and consistent enough.
"It hurts that I've lost because this is my first Olympics. I feel just disappointed, the support was amazing, I feel like I kind of let everyone down as well. I gave it my all."
Asked about the fact that she will not play in the mixed doubles, after Laura Robson was selected to play with Murray, she added: "I was hoping to get in.
"I thought I might have deserved a spot in the mixed because of my ranking, because of how well I've been doing, especially winning a title last week.
"I'm just upset that I didn't get picked, but there's not much I can do."
Robson put up a good fight against Sharapova, and the 18-year-old Briton said: "It's always tough playing the number three in the world.
"She won the French Open so she's obviously in great form and I had chances I didn't take. It's definitely disappointing.
"It's tough playing against someone like that because you have to go for so much on your serve, otherwise she's just going to start ripping returns. She definitely puts you under pressure."
Murray outclassed Nieminen in an hour and one minute and has now won all four meetings between them.
After securing an early advantage, he raced into a 3-1 lead and secured the double-break with a crunching backhand volley.
Murray fended off Nieminen's only opportunity before serving out the first set and striking in game one of the second with a defensive lob.
Nieminen scrambled to remain in contention but he could not deal with the power, precision and variety of his opponent.
Murray received loud support from the spectators all match and he saluted them after wrapping up victory with an ace out wide.
"When you play in front of packed crowds it helps," said the 25-year-old. "When it's home support and it's with you it helps a lot.
"The atmosphere has been great since the first match. Hopefully I can keep going because it's fun to play in an atmosphere like this."
