Murray into last four

Britain’s Andy Murray set up a potential semi-final meeting with top seed Andy Roddick after beating Stefan Koubek 6-3 6-2 in the quarter-final of the Morgan Keegan Championships in Memphis.

Having beaten Denmark’s Kristian Pless in two sets to secure his showdown with Koubek 24 hours earlier, Murray was already showing the kind of form that brought him victory at the SAP Open in San Jose last week.

The 19-year-old was quickly into his stride and while his own serve looked strong he soon broke his Austrian opponent.
