He's only played one tie a year since 2003. He lost several doubles rubbers and his singles were all against low ranked opps, except Czech Republic.
He played 15 matches without losing. This is not so bad, considering the fact he was always under enormous pressure, because Stan is not a very reliable Daviscup partner to say the least.
As I have said before, Roger could never count on a team with strong players like many other nations.
