Bad match from both teams on the whole - the Murray brothers played a patchy match, although they got better after a dreadful first set and were just the better team in the end, but Nestor had one of his worst matches of the season and he dragged Niemeyer down as well.
They got lucky, but they'll have to play better in the next round, which won't be tomorrow, but on Wednesday.
They'll probably face Clement/Llodra who led 6-4, 5-4 when rained stopped play... and it's unlikely to get back on today, so will be continued some point tomorrow night, after Llodra plays his singles match.
And they need to sort out whatever went on between them, as they didn't look happy with each other - they barely talked throughout the match and when they did it wasn't very happy, and Andy walked off the court straight away after winning... something isn't right between them, but at least they got through
