Why Roddick did not get any points from Lyon?
Only the top 18 results count for the race, with 4 the Grand Slams and 9 the Masters Series.
Roddick's other 5 best:
San Jose 35
Since he earned just 11 points at Lyon, it does not count as part of his top 18, and doesn't help him at all. He would have needed at least a final to increase his points.
