They hit 22 winners to 14 and served remarkable well, winning 81 percent on their first serve and converted three of their eight break point opportunities.
The pair will next face Korean wildcards Min-Kyu Song and Ji Sung Nam for a place in the third round for the second straight year. The pair of 30-year-old Koreans are both ranked outside the top 100 but upset New Zealand-born Ben McLachlan, who represents Japan, and India’s Rohan Bopanna in the first round.
