Dubai, United Arab Emirates (SportsNetwork.com) - Multiple champion Novak Djokovic and former runner-up Andy Murray were a pair of second-round winners Wednesday at the $2 million Dubai Tennis Championships.

The world No. 1 Djokovic drubbed Kazakhstan's Andrey Golubev 6-1, 6-2, while the third-seeded Murray mauled Portuguese Joao Sousa 6-0, 6-2 at this lucrative hardcourt event.

The Wimbledon champion Djokovic beat Murray in last month's Australian Open final.

Djokovic is a four-time champion in Dubai, winning three straight titles here from 2009-11 and prevailing again in 2013. Murray was the runner-up here in 2012.

Fourth-seeded Tomas Berdych captured his 500th career match victory by holding off Italian Simone Bolelli 7-6 (9-7), 5-7, 6-0. Berdych lost in the previous two Dubai finals, including last year against six-time champ Roger Federer.

Meanwhile, former top-10 Frenchman Richard Gasquet derailed seventh-seeded Spaniard Roberto Bautista Agut 6-4, 3-6, 7-6 (8-6).

Additional second-round results saw Ukrainian Sergiy Stakhovsky best Uzbekistan's Denis Istomin 6-4, 3-6, 6-4 and rising Croatian teenager Borna Coric get past former Aussie Open runner-up Marcos Baghdatis 6-4, 3-6, 6-6, as "Baggy" retired before the start of the third-set tiebreak.

This year's Dubai champ will earn $505,000.
