Paris: Andy Murray's heroics for Britain in the Davis Cup at the weekend have seen him rise back up to fourth in the ATP world rankings.

Murray defeated both Donald Young and John Isner as he spearheaded his side to a win over the United States in Glasgow in a World Group first round tie. That helped the Scot move back ahead of Kei Nishikori who won both of his singles for Japan against Canada but still finished up on the losing side.
