Serbia's Novak Djokovic beats Czech Tomas Berdych to level Davis Cup final at 2-2

Novak Djokovic kept alive Serbia's hopes of winning its second Davis Cup title in four seasons by beating Tomas Berdych of the Czech Republic in the first reverse singles match Sunday to even the final at 2-2.

Second-ranked Djokovic won 6-4, 7-6 (5), 6-2 to improve his career record against Berdych to 15-2.

The best-of-five series will now be decided in the final match between Radek Stepanek and Serbian cup rookie Dusan Lajovic.

Djokovic, who improved his winning streak to 24 matches since September, converted his first match point with an ace, bringing cheers from the boisterous Serbian crowd at Belgrade Arena.

The Czech Republic is defending the title. Serbia won its only Davis Cup title in 2010, beating France in Belgrade.
