No, just me forgetting that Rafa was on the top 10 list already. What's the explanation for that discreprency with Sampras? He was very close (about 50 points), from dropping to 7th.
It is a simple case of an ATP typo, I guess.
The week in question is week of the WTF. In the WTF Sampras was ranked 5, and grouped with Agassi (1), Kuerten (3) and Lapentti (8). So there is no doubt he was 5th not 7th. Even though, as you say, he was very close to dropping out.
No sweat for Roger, though. He has long since passed Sampras' corrected total. Only Connors and Lendl ahead of him.
