Andy Murray is through to the final of the Erste Bank Open after David Ferrer pulled out of their last-four meeting due to injury.

Top seed Murray, who has the chance to become world number one before the end of the year, was given a walkover because of a leg problem sustained by defending champion Ferrer ahead of Saturday's semi-final match in Vienna.

The top seed Scot will now face Jo-Wilfried Tsonga or Croatian Ivo Karlovic in Sunday's final.

Murray is chasing down Novak Djokovic at the top of the ATP world rankings, with one win in the Vienna Open edging him closer to that objective.

Should Murray win in Austria and back that up by winning the Paris Masters, with Djokovic failing to make the final of the ATP 1000 event, the Scot will be number one by November 7.
