What are we feeling today, another convincing victory, or more of a struggle for Murray?
Lu has got some Wimbledon pedigree, reaching the quarter finals back in 2010 including a five-set win over Andy Roddick.
Clever shot from Lu to wrong-foot Murray. The Scot has a little stumble but looks OK.
Good smash from Lu who is far from over-awed by the occasion. 30-30.
@RobertC - He is certainly looking up for the challenge so far!
Laura Robson is preparing to face Colombia's Mariana Duque-Marino with the match scheduled to be next on Court Two.
Duque-Marino, 23, is a qualifier, ranked 117 in the world but did record an impressive victory over Germany's Julia Goerges in round 1.
Robson has never faced Duque-Marino, who has never been beyond the second round of any Grand Slam.
Play is currently delayed due to rain.
Let's try again! Welcome to the live Wimbledon blog for day five. Rain ruined our day yesterday with Laura Robson's match delayed but she is in action shortly.
The rain is still coming down at SW19 but Britain's number 1 has been moved to Centre Court so she will definitely be in action shortly against Colombian qualifier Mariana Duque-Marino.
People with Centre Court tickets today are in for a real treat with Andy Murray also in action later this afternoon, but first it is all eyes on Robson who also has a doubles match scheduled today!
Robson is looking a bit nervous as she comes out on court, but hopefully the home crowd will be a real help. It will be interesting to see how she copes with being favourite this time around.
Good news on the outside courts too, with covers coming off!
Mariana Duque-Marino won the toss but decided not to serve first. Time has been called and Laura Robson will serve soon.
Big applause for Robson as we get underway.
@daft Davey - Hopefully not involving our Brits though!
Duque-Marino has a heavily strapped upper thigh. Will see if that is a problem during the match.
@daft Davey - oh? Seems to have got some votes on it. Try refresh maybe?
Couple of unforced errors, sloppy start from Robson who finds herself 0-30 down.
