Nikolay Davydenko seals Masters semi spot

Nikolay Davydenko swept past Juan Martin del Potro 6-3 6-2 to book his place in the Masters Cup semi-finals.

With a win apiece in the Gold Group, there was all to play for and the pair swapped breaks in a sluggish first set.

But Davydenko soon took control, breaking Del Potro again to take the opener before a double break in the second saw him stroll to victory.

Novak Djokovic advanced as the Group winner though he lost his final game 1-1 7-5 6-1 to Jo-Wilfried Tsonga.
