Perhaps some early nerves as Robson sends two early points long and trails 15-30 in the opener.
GAME NA 0-1 - Nightmare start for Robson as she loses the opening game with serve. Will want to bounce back straightaway as that was sloppy from the Brit.
GAME NA 0-2 - A dominant start as Li Na races into a 40-0 lead. But Robson rallied back to 40-30 only to force one just long to give the Chinese player a 2-0 first set lead.
Not many people in Arthur Ashe court this early (11am NY time), but a few woops of encouragement for Robson as she comes out to serve.
GAME ROBSON 1-2 - And Laura gets off the mark. Na Li had a break point chance but some good shots from the Brit ensures she holds serve.
This is the first tournament where Laura Robson has been seeded so for once she has not exceeded expectations at all by reaching this stage. Na looking confident so far.
First challenge of the day and it comes from Robson. The ball was called out and it was.... out. Just.
Can Robson turn it around or is Li Na's revenge mission going to be unrelenting? Set two underway now, Robson serving.
Li Na charging all around the court but much better from Robson with a little fist pump after Na goes long.
The crowd are certainly in Robson's corner, with good applause as she has break points for the first time in the match.
Mentioned earlier Mayer and Murray share the same birthday. That is pretty much where the similarity ends though in terms of what both have achieved in the game. Mayer has 1 career title, Murray has 28. Not to mention the two Grand Slam titles...
New balls! Mayer doesn't seem to be taking to them too well. Finds himself 0-30 down on serve. Could this be the first slip up from either player on their service game?
Change of shirt for Mayer. Fluorescent yellow to a white one. Could nearly get away with playing in that kit at Wimbledon. May have to change the socks though...
