He said he's chatted to Leon about it, and they'll decide nearer the time. It's a possibility, but as someone already said in this thread, without a decent #2, it's probably better for British men's tennis long-term for Andy to achieve big, headline making personal goals, than for him to prop up the Davis Cup team - even Leon said as much.
Part of it is the timing, which looks promising compared to some of them, but there's also the change of surface to consider, and whether or not adding an extra one into the mix (as well as reducing prep time) is likely to cause bother with Andy's knee etc. I think he'd love to play, and even though he should win his matches easily, they are all three setters. I sometimes think they should reduce them to two sets, except for the finals, especially in the lower groups where mis-matches are more likely.
My apologies if I've misread your post, but the matches are best of five here, although Andy might be expected to win in three, but in the lower groups, and by that I mean Groups III and IV where you have countries like Bermuda and Iraq playing, it's a round-robin set up with matches best of three.
I'm not sure if the surface would be a problem because the tie will be played indoors, so Andy would only be moving from one hard court surface to another, and then onto clay, although I do realise that hard court surfaces can vary.
It's good to know that he has spoken to Leon about playing though, and at least Leon won't put any pressure on him like John Lloyd did.
