SIBIU, Romania — Dimitry Tursunov beat Romania's Victor Hanescu 4-6, 5-7, 6-3, 6-4, 6-2 to give Russia an insurmountable 3-1 lead in their first-round Davis Cup series.

Russia will advance to the quarterfinals.

Tursunov only dropped three points on his serve in taking the fourth set, and broke Hanescu in the first game of the fifth to prevail in a match that lasted nearly four hours.

Russia won the Davis Cup in 2006, then lost the final to the United States the next year. Romania has never won the tournament, and played its first Davis Cup match under new captain Andrei Pavel.
