Canadians Erik Chvojka and Vasek Pospisil won their opening matches on Tuesday at the $35,000 ATP Rimouski Challenger tennis event in Quebec.
Pospisil, from Vernon, led 3-0 in the opening set when his Belgian opponent, Alexandre Folie, was forced to retire because of a right shoulder injury that hampered him on his serve.
Pospisil, the tournament’s second seed and a 2011 semifinalist in Rimouski, will play Germany’s Jaan-Frederik Brunken in the second round on Friday.
Montreal’s Chvojka took on Haydn Lewis, a qualifier from Barbados. He saved all three break points he faced and broke his opponent’s serve once in each set en route to a 6-3, 6-4 victory.
