Good morning. It's the second day of the Tennis Masters Cup in Shanghai. First Roger Federer plays Gilles Simon, and then Andy Murray will face Andy Roddick.

Federer lost his first match after Wimbledon this year to Simon, in Toronto, and they have not played each other since. This was their only encounter to date.

Andy Murray's head-to-head with Andy Roddick is 4-2, but they haven't played each other since Miami in 2007, which Murray won when Roddick was forced to retire. It's always interesting when these two play each other: the serve versus the return of serve, and the fact that they have both been coached by Brad Gilbert.

Please use this thread to discuss the matches in Shanghai as they unfold. After the tennis is over, it's OK to drift off-topic.

I took today's picture in Paris two weeks ago. Not many ATP players appear to have eyelashes that long.

As always, enjoy the tennis.
