Thanks, Voo! I really appreciate it
Can't believe I was so daft, after all - it reads 0-3 in TB challengers further down the Sampras page
Interesting, by the way. By "normal" ATP standard those challenger TBs shouldn't have been counted as they were played before 1991. I checked Nastase's page to see if stats made entirely before 1991 were correct, but his TB status is 14-6....I have no idea which 20 they count, certainly not his last 20.
This is because the ATP count the TB where they have the scorelines, by this is than older players have some TB in their own page.
