I have voted for Andy in straights, but I doubt the time will be exact.
Christophe Rochus had a very bad year last year, he beat Beto Martin reasonably easily though in the first round, and Martin is ranked higher than he is. Andy should be too much for him unless he plays really badly.
im not sure whether a seperate thread is needed but the murray brothers will play their doubles match 3rd on court 1, with play commencing at 3.15 Qatar time, the match should start around 4.30pm GMT
