Tomas Berdych is into the last four of the Stockholm Open following a routine win over Grigor Dimitrov.
The top seed came through in an hour and 29 minutes against the fifth seed, prevailing 7-5 6-4 in the Swedish capital.
Berdych faced just two break points and won 85 per cent of his first serve points in a solid display, with a sole break in each set enough to set up a semi-final with Marcos Baghdatis.
Baghdatis outlasted eighth seed Gilles Muller to progress 7-6 (7-5) 4-6 6-3 after two hours and 24 minutes.
Second seed Richard Gasquet was also made to work hard for victory in the all-French quarter-final as he beat Jeremy Chardy in three sets.
Having seen Gasquet fight back from losing the first set to force a decider, Chardy displayed some resiliency of his own by breaking back to level the third at 5-5 and then stood firm to force a tie-break.
But world number 12 Gasquet’s quality told in the shoot-out as he secured a 2-6 6-3 7-6 (7-4) success.
Gasquet will face Jack Sock in the last four after the American saw off another Frenchman in Gilles Simon, 7-5 7-6 (7-5).
