LONDON — Roger Federer and Andy Murray easily secured spots in the semifinals of the ATP World Tour Finals on Thursday with straight-sets victories in their last round-robin matches.

Federer continued his dominance over Robin Soderling, beating the Swede 7-6 (5) 6-3 to earn top spot in Group B of the season-ending tournament. Murray followed up by recovering from a shaky start to beat David Ferrer 6-2, 6-2 to hand the Spaniard his third straight loss in the group phase.

Their semifinal opponents will be decided today, when the last round-robin matches in Group A are played.

Federer won his third straight group match and improved his career record against Soderling to 15-1, with his only loss to the Swede coming in this year's French Open quarterfinals.

"(Soderling) always brings out something different every time he plays me, because he has to try different things," Federer said.
