Scotland's Andy Murray defeated Jo-Wilfried Tsonga 6-2, 7-6 (7-3) here Friday night at the Barclays ATP World Tour Finals to advance to the final four of this year-end event for the third time.

Murray needed only to win one set against the Frenchman to qualify for the semifinals after world No. 1 Novak Djokovic defeated Czech Tomas Berdych 6-2, 7-6 (8-6) in Group A action earlier in the day at London's O2 Arena.

Tsonga's chances of advancing to the semifinals slipped away quickly when he dropped the first four games of the match. He was officially eliminated from the tournament after losing the first set a few games later.

Playing for pride, Tsonga rallied from a 4-2 deficit in the second set to force a tiebreaker, which Murray won handily.

"In some ways, feels like you're serving for the match when you know you're through if you win that," Murray said of clinching the first set. "I was very focused from the start of the match. I got off to a good start."

"I'm somebody who never give up," Tsonga said about his second-set effort. "So sometimes you are not playing a good tennis, and you keep fighting, you keep believing in you, and then it comes better and better."

Djokovic finished as the top player in Group A and will play the No. 2 player from Group B in Sunday's semifinals.

Roger Federer, winner of this event a record six times, has already qualified for the semifinals from Group B. The Swiss will play Murray at that stage if he defeats Argentina's Juan Martin del Potro in his final round-robin match Saturday.

The other Group B match Saturday will pit Spain's David Ferrer against Serbia's Janko Tipsarevic.

Murray advanced to the semifinals of this event in 2008 and 2010 but has never reached the championship match.

The eight-man Barclays ATP World Tour Finals is the biggest tournament on the men's tennis calendar after the four Grand Slams.
