Marcos Daniel ensured a second Brazilian presence in the semi-finals with a fine 6-4 7-6 (7/1) win over France's Florent Serra, including a comeback from 1-4 behind to take the first set.

Daniel's next opponent will be the world number 51 Andreas Beck, who earned his place in the last four with a 6-4 7-6 (7/5) win over the unseeded Romanian Victor Crivoi.
