Top seeds Mahesh Bhupathi and Max Mirnyi of Belarus continued their winning run on the ATP Tour, advancing to the doubles semi-finals in the $2.2 million Tennis Masters Tournament in Cincinnati, USA.

The duo beat eighth seeds Martin Damm and Cyril Suk of Czech Republic in two close sets, 7-6 (7/4), 6-4.

The pair is now third in the doubles Champions race. In the individual doubles ranking, Mirnyi is ranked No. 1 while Bhupathi is No. 2.

The Wimbledon runners-up, who won their third title of the season in the Montreal Masters Tournament in Canada last week, will take on seventh seeds Wayne Arthurs and Paul Hanley of Australia for a place in the final.

But before his doubles match, the 6'5" Belarussian will be first out on centre court to challenge American Andy Roddick in the singles semi-finals. Mirnyi is the first player to reach both the semis at Cincinnati after Russian Yevgeny Kafelnikov achieved the feat in 1998.

In the other doubles semi-final, second seeds Bob and Mike Bryan of United States will meet third seeds Mark Knowles of Bahamas and Daniel Nestor of Canada.
