Federer leaves Murray reeling

The 29-year-old Federer, bidding for a record-equalling fifth title at the year-ending showpiece had often struggled against Murray in their 13 previous encounters but he cruised to victory with a minimum of fuss.

The writing was on the wall for Murray when he had to save break points in the opening game but Federer broke to love on the Scot's second service game -- an advantage he never looked like relinquishing.

His usually trusty groundstrokes lacking bite and accuracy, Murray managed only three points on the world number two's serve as the opening set slipped by in 36 minutes.
The crowd hoped for a response from Murray but they were to be disappointed as the 23-year-old unravelled before their eyes and he quickly went 4-0 down in the second set.

On Monday, Rafael Nadal registered a compelling round robin victory over Andy Roddick. Novak Djokovic’s win over Tomas Berdych had provided the day's biggest talking point until world number one Nadal slugged out a 3-6, 7-6, 6-4 victory. A razor-sharp Djokovic outclassed a disappointing Berdych 6-3, 6-3.

Paes-Dlouhy lose

Leander Paes and Lukas Dlouhy’s chances suffered a setback due to defeat in the opening group match.

Paes and Dlouhy, seeded third, though went down fighting 3-6, 6-7 (3-7) against Mariusz Fyrstenberg and Marcin Matkowski.

Paes and his Czech partner will have to win the remaining two matches as only the top two teams from each group will advance to the semifinals.
