Roger Federer vs. Andy Murray: Score and Recap from 2014 ATP World Tour Finals

Andy Murray's ATP World Tour Finals came to an abrupt end at the O2 Arena in London on Thursday, as he was categorically outplayed by a magnificent Roger Federer. The Swiss recorded the 6-0, 6-1 victory.

Murray needed to beat Federer in straight sets to advance from the round-robin group stage—he lost to Kei Nishikori but defeated Milos Raonic his two previous matches—but he was on the back foot from the match's third point.    

Federer had already been confirmed as a semi-finalist pre-match, but he secured top spot in Group B with the win and took Nishikori through with him to the knockout rounds.

Federer won the coin toss and chose to serve first, and Murray got into a strong position as the Scot went 30-0 up.

However, a long third-point rally eventually ended with Murray netting, and, though early, it proved to be a key moment of the match.

The Swiss legend grabbed the advantage, eventually winning his opening service game and bulldozing Murray from that moment on.

The 17-time Grand Slam winner produced stunning variety with a selection of fantastic backhands and beautifully executed net play to break Murray three times and claim the opener 6-0. That first set loss effectively knocked Murray out of the competition, per the BBC's Russell Fuller:

Federer was relentless in the second set as he continued to put the Scot on the back foot.

The 33-year-old had praised Murray's recent form before the match but seemed to have little trouble Thursday, per Paul Newman of The Independent:

"[There were] matches he needed to win down the stretch at the end of the season, which he did," said Federer. "That’s why I’m sure his belief is higher now again."

While Murray had more than a few unforced errors, Federer's quality of play was so high there was little way back no matter how well the Scot played.

Federer's serve was almost flawless, as he cruised 3-0 into the lead in the second set, per BBC Tennis:

Murray finally won a game in the sixth game of the second set, coming back from 15-30 down. He got himself on the board with an unreturnable serve and avoided an ignominious personal record, per ESPN UK: 

However, Federer sailed through his final service game, as he forced Murray to send a backhand wide to win the match 6-0, 6-1.

Federer marches on into the semi-finals where he will likely face Stan Wawrinka or Tomas Berdych. The Swiss is attempting to win a seventh ATP World Tour Finals title.

A final against Novak Djokovic is almost inevitable at this point. It would be a fitting end to the season since the two have been phenomenal throughout the year.
