Ferrer books semis spot

David Ferrer got his season off to the perfect start as he came from a set down to beat Nikolay Davydenko and reach the semi-finals of the Capitala World Tennis Championship in Abu Dhabi.

The Spaniard, who only claimed a place in the exhibition event after Jo-Wilfried Tsonga was forced to withdraw with a wrist injury, struggled in the opening set as ATP Tour World Finals champion Davydenko prevailed 6-2.
