Murray through to US Open fourth round

Andy Murray had another frustrating afternoon on the Louis Armstrong Stadium court but did enough to defeat Andrey Kuznetsov and reach the fourth round of the US Open.

There was not the same drama as there had been in round one, when he cramped against Robin Haase and might have lost, but Murray again found himself embroiled in a fight having appeared in total control against a player ranked 96th in the world.
