Top seed Grigor Dimitrov eased into the semi-finals of the Nastase Tiriac Trophy with victory over Sergiy Stakhovsky.
The 22-year-old Bulgarian needed less than 70 minutes to see off Stakhovsky, recording a fairly comfortable 6-3 6-4 win.
Dimitrov, ranked 16th in the world, will now face third seed Gael Monfils in the final four after the Frenchman overcame compatriot Paul-Henri Mathieu.
Qualifier Mathieu started brightly, securing the first set and taking the second to a tie-break before Monfils fought back to level the match. He then eased to success in the decisive set to win 3-6 7-6 (10/8) 6-2.
Gilles Simon could not make it three Frenchmen in the semi-finals as he fell to Lukas Rosol 7-6 (7/2) 6-2 with Robin Haase waiting for the Czech on Saturday.
Haase had beaten second seed Mikhail Youzhny on Thursday and the world number 47 continued his good form to beat Denis Istomin.
Istomin looked to have the beating of Haase as he took the first set but the Dutchman stormed back to progress 3-6 6-1 6-3.
