Defending champion Andy Murray beat Tomas Berdych 6-3 6-2 to progress to the semi-finals of the Madrid Open.
The Scot produced arguably his best performance of the season to record a first win over the Czech on clay.
Murray, who beat 16th seed Gilles Simon to reach the quarter-finals, won 92% of his first-serve points and denied eighth-seed Berdych any break points.
The world number two, 28, will next face either Rafael Nadal or Joao Sousa in the last four at La Caja Magica.
Home favourite Nadal, who is looking for a third successive tournament victory following his wins in Monte Carlo and Barcelona, meets Portuguese world number 35 Sousa later on Friday.
