Former champion Mikhail Youzhny booked his place in the second round of the St Petersburg Open on Tuesday with victory over Vasek Pospisil.
The 30-year-old top-seeded Youzhny, who won the title in 2004 and has also twice been runner-up, battled through a tight first set and then broke the Canadian twice in the second for a 7-6 (7/4) 6-1 win.
Slovakian fifth seed Lukas Lacko was a surprise casualty, beaten 6-3 6-2 by Slovenia's world number 69 Grega Zemlja, who broke his opponent's serve five times in the course of their match.
Sixth seed Yen-Hsun Lu of Chinese Taipei also fell, 6-4 6-2 to Spain's world number 87 Roberto Bautista-Agut, while another Spaniard, Daniel Gimeno-Traver, beat Florent Serra of France 7-6 (7-5) 6-2.
