Roger Federer dominated Andy Murray yesterday at the ATP World Tour Finals and stretched his record to 2-0 at the season-ending event by winning 6-4, 6-2.

Federer looked unstoppable on the court at the O2 Arena, losing only eight points on his serve in the match — three in the first set and five in the second.

"It's a bit strange," said the second-ranked Federer, who won 63 points to Murray's 43. "Andy's a good returner, one of the best we have in the game."

Besides controlling play with his serve, winning 88 percent of the points when he landed his first serve, Federer also forced Murray into long rallies when he was receiving. Pulling forehands to his left and hitting them to his right with ease, the 16-time Grand Slam champion waited for his British opponent to make the errors or set up his winners.

"I don't think Andy played his best match for sure," Federer said of his opponent, who made 26 unforced errors.

Federer has won the season-ending event for the top eight players in the world four times, and he can certainly add to that if he keeps playing like he did Tuesday.

Murray, however, dropped to 1-1 and will have to improve if he is to reach the semifinals. He will face Ferrer in his final match tomorrow while Soderling takes on Federer.

Murray struggled from the start yesterday, forced to save a break point in the opening game. And it was his serve that was letting him down most of the way, landing only 44 percent of the first serves. That allowed Federer to take advantage of the much slower second serve.

"I returned poorly, served poorly," Murray said. "Against him, that's not going to win you the match."

Federer earned his first break in the third game of the first set, winning all four points played. He then won his next three service games at love.

In the second set, Murray saved two break points in the opening game, but Federer stayed alive through four deuces to earn a third break point, which he converted with a forehand that hit the top of the tape and zipped past Murray.

After holding at love yet again, Federer broke again to make it 3-0 and soon led 4-0.

"I tried to play quite aggressive. You're not going to hit winners every single time you go on the court," said Murray, who is 8-6 overall against Federer. "Today I made more mistakes than normal."

On Monday, top-ranked Rafael Nadal rallied to beat Andy Roddick 3-6, 7-6 (5), 6-4 and third-ranked Novak Djokovic defeated Tomas Berdych 6-3, 6-3.

Nadal will take on Djokovic today, while Roddick and Berdych play in the early Group A match.

In the other match from the Group, Sweden’s Robin Soderling obtained his victory beating Spaniard David Ferrer in two tightly contested sets.

In the end Soderling had the edge winning 7-5, 7-5. With this victory Robin Soderling remains in the hunt for a semi final place, even though his task will be an ardous one.

Having lost against Murray in the first match Soderling now needs to beat the already qualified Roger Federer, and hope in a David Ferrer victory in the other match against Andy Murray.

David Ferrer is completely out of contention having suffered two straight defeats against Federer and Soderling, and has yet to win a set in his first ever appearance in the end of season showcase.
