Tomas Berdych has kept alive his hopes of making it through to the semi-finals of the ATP World Tour Finals with a three-set victory over Jo-Wilfried Tsonga.
The win was Berdych's first of the tournament, while Tsonga has now lost both of his opening two matches.
Tsonga saved three break points in the opening set, but he wasn't able to stave off a fourth as Berdych broke before seeing it out 7-5.
The Frenchman levelled the match by taking the second 6-3, only for Berdych to then break twice and power through the third 6-1.
