On a sweet-sour day for India, Mahesh Bhupathi and Mark Knowles cruised into the semi-finals of the men's doubles but the top-seeded mixed doubles pair of Leander Paes and Cara Black were shocked in the second round of the Australian Open today.

The third-seeded Indo-Bahamian duo of Bhupathi and Knowles overcame a second set deficit to beat the Spanish pair of Feliciano Lopez and Fernando Verdasco 6-1, 2-6, 6-4 in one hour and 28 minutes.
