Belarus, mainly thanks to their ultra fast court, hasn't lost a DC tie at home since 1995, at least according to this site
However, Söderling beat Voltchkov 6–3, 7–6 (7–3), 6–1 and ToJo def. Mirnyi 6–4, 6–4, 6–4yesterday, so the streak could very well end here. Funny detail: Björkman against Mirnyi in today's doubles, will Jonas again be his partner's nemesis? (He leads their h2h in singles 10-1!)
I didn't see any of the matches, nice if someone could add comments.
