Perfect Djokovic makes semis

Novak Djokovic powered into the semi-
finals of the ATP World Tour Finals with
a perfect record after beating Tomas
Berdych for a third win out of his three
round robin matches.
The world number one was in
impressive form as he saw off Tomas
Berdych 6-2 7-6 (8-6), after saving
three set points in the second set.
Djokovic is now guaranteed to top
Group A while Berdych is out, and
Andy Murray only needs a set against
Jo-Wilfried Tsonga tonight to ensure he
will also qualify for the last four.
Berdych had beaten Djokovic only once
in 11 previous meetings, in the semi-
finals of Wimbledon in 2010, and he
was soon under pressure.
Djokovic's famed returns were rushing
the Czech and, although he clawed his
way back from 0-40 in the third game,
a fourth chance arrived and the world
number one took it.
Djokovic, whose best performance at
the O2 was a semi-final appearance in
2010, looked extremely sharp and he
made it five games in a row before
Berdych finally stopped the rot.
The top seed comfortably held to win
the set, though, and with that assured
himself qualification for the last four.
Berdych appeared to have no answer
when Djokovic broke again in the third
game of the second set but he began
to take the fight to his opponent a bit
more and hit back to level at 2-2.
Berdych made a flying start to the tie-
break, winning five of the first six
points, but Djokovic did not give up
and saved two set points on his own
serve before another trademark return
at Berdych's feet levelled matters at 6-6.
The top seed then added a fourth
point in a row and clinched victory
when Berdych fired a return long.
