Game Set and Match to GB - last game held to 15.
GB win the tie by 3 points to 1
Looks like the 5th match is going to be played, even though the outcome of it will be of no real significance as far as the Tie is concerned. Personally it will be great for Dan Evans if he can beat the Australian.
GB to serve first.
Off to a good start as GB win the first game quite easily.

Game and first set to Australia
Great effort from GB and Andy Murray in particular.
Hopefully Argentina win to give GB home advantage for the final.
They only played 2 sets in the end, both won by Australia.
Belgium have won the other semi-final against Argentina. So the final for GB will be an away match.
News this morning that because Belgium is likely to go for clay courts to have a better chance against Andy Murray that he may decide to miss the World Tour finals at the O2 arena in London played a few days before the Davis Cup final putting playing for GB ahead of personal financial gain.
