Spain's David Ferrer has been eliminated from the Barclays ATP World Tour Finals after a 6-4, 6-4 loss to Czech Tomas Berdych in the round-robin phase of the tournament.

The world No. 3, who has played for seven consecutive weeks at events in Asia and Europe, also offered less resistance than usual in a 6-3, 6-2 loss to top-ranked Rafael Nadal on Tuesday in Group A.

In Wednesday evening's match, Berdych frustrated Ferrer with big serves and also rock-solid consistency and defense when the Spaniard was able to take the initiative in the rallies.

Although Ferrer had admitted feeling fatigue after his loss to Nadal, he came out strong and struck his ground strokes with authority in the early part of the match.

Berdych's power, however, allowed him to control his service games and eventually create break-point opportunities against the Spaniard, finally capitalizing on his fourth chance to give himself the decisive edge in the first set.

Ferrer stayed close in the second set, but a costly service break at 4-4 ended the Spaniard's London hopes.

Nadal claimed a berth in the semifinals by defeating Swiss Stanislas Wawrinka on Wednesday. Either Berdych or Wawrinka will secure the other Group A spot depending on their results on Friday.

Play in Group B resumes on Thursday with Swiss Roger Federer taking on Frenchman Richard Gasquet and world No. 2 Novak Djokovic of Serbia squaring off against Argentine Juan Martin del Potro. EFE
