The Latvian was made to work hard to defeat FilippoVolandri 6-2 3-6 7-6 and next faces Spaniard Feliciano Lopez, who progressed when opponent Ivan Ljubicic withdrew with a side strain.
The top quarter of the draw has a surprising look following the early exit of top seed Roger Federer, with his conqueror Ernests Gulbis beating FilippoVolandri 6-2 3-6 7-6 (7-4) to set up a clash with Feliciano Lopez, who had a walkover after Ivan Ljubicic pulled out with a back injury.
