Singles matches may be given pride of place at Wimbledon, but the mixed doubles drew the attention of social media when Andy Murray and Serena Williams paired up at SW19.

It had been 724 days since Murray last competed on Centre Court, and as such mum Judy was among the first to settle down for the game.

"Dear Andy and Serena. I'm ready," she tweeted.

Meanwhile tennis great Billie Jean King replied to Judy's message with Murray's famous "Let's go!" shout.

And it didn't take long for nicknames to start flying around, the WTA's Instagram page going with "SerAndy".

British tennis player Katie Boulter gave her followers some idea of how intimidating a pairing it was.

"Genuinely though, how do you prepare to play against Andy Murray and Serena Williams at the same time?!!" she tweeted.

Murray and Williams showed their class in the first set, but, as ever with mixed doubles, entertaining moments were never far away.

And some spectators were quick to notice how easy the relationship between the two Wimbledon champions was.

MP John Woodcock took to social media to describe the "privilege" of watching Murray and Williams play together, while Olympian Chris Hoy said of his day at the tennis: "managed to catch some of the 'Andy and Serena Show' which was an added bonus!"

Twitter was the place to be for King, who commented "Bravo!" on Murray and Williams' first-set win.

And when the convincing 6-4 6-1 triumph was complete, the pair sealed it with a kiss.

"Well that was fun" Murray tweeted shortly afterwards.

It's fair to say a mixed-doubles pairing has rarely commanded the attention of social media in the way that 'SerAndy' did on Saturday evening.
