Second seeds Mahesh Bhupathi and Max Mirnyi entered the quarterfinals of the men's doubles competition at the Australian Open in Melbourne on Sunday.

The Indo-Belarussian pair defeated Hicham Arazi of Morocco and Nicolas Mahut of France in straight sets 6-3, 7-6 (7-4).

The duo will take on fifth-seeded French pair of Michael Liodra and Fabrice Santoro in the quarter-final.

In the mixed doubles, however, Bhupathi, paired with Elena Likhovtseva of Russia and second seeded, could not keep the momentum and lost in an exhausting first round match.

Bhupathi-Likhovtseva were upset by the unseeded pair of Russian Jeff Coetzee and Slovakia's Tina Krizan 7-6, (7/5), 4-6, 7-6 (10/8) in a long-drawn match.
