Defending champion Lukas Rosol is through to the semi-finals of the Nastase Tiriac Trophy in Bucharest after a straight-sets win over Gilles Simon.

A poor start by the Frenchman saw Rosol race into a 4-1 lead in the first set, however Simon fought back and managed to take the set to a tie break.

Simon took the first point, but Rosol the next six before the Czech secured the set 7-2.

Strong winds persisted throughout the match and Simon was very unhappy to be detained on court when the rain arrived early in the second set.

At 2-1, he had his way and there was a 15-minute stoppage.

However, the break favoured Rosol far more as the Frenchman won only one more game.

Rosol in the end completing a comfortable 7-6, 6-2 win.

A strong start from Denis Istomin in the day's second quarter-final tie.

The Uzbek broke Robin Haase's second service game and went on to take the opening set 6-3.

The momentum swung wildly in the other direction in the second though.

Haase swept the next five games, to race to take the set 6-1.

The Dutchman retained control in the decider, securing a 3-6, 6-1, 6-3 win.
