Montreal Masters: Nick Kyrgios, Juan Martin del Potro move into second round; Lucas Pouille ousted

Montreal: A still-hurting Nick Kyrgios cruised into the second round of the ATP Montreal Masters on Monday with a 6-1, 6-2 victory over Viktor Troicki.A 51-minute outing was just what the doctor ordered for 16th-seeded Kyrgios, who had retired from his three prior matches because of injuries.[caption id="attachment_3906617" align="alignleft" width="380"]

"I wake up, I want to play. And then I wake up and, I don't know, some days I don't."I felt good today, obviously. I didn't feel like I hit the ball extremely well. I didn't serve great. I thought I served OK. But he played far from his best tennis," Kyrgios said.Troicki has struggled of late with injury as well, also retiring from his first-round match at Wimbledon."We're kind of in the same boat," Kyrgios said.Kyrgios broke Troicki twice in each set while never facing a break point. Even so, he needed seven match points to finally put the 45th-ranked Serb away.Kyrgios's run of injury trouble has derailed what started out as a promising season for a player whose talent has often been overshadowed by his tantrums.He reached the semi-finals at Marseille, Acapulco and Miami, and notched impressive victories over Novak Djokovic at Marseille and Indian Wells.But illness forced him out of his scheduled Indian Wells quarter-final against Roger Federer, and he withdrew from Monte Carlo with elbow trouble and Rome with the hip injury that continued to dog him through Wimbledon."I'm getting a lot of treatment, trying to do my rehab every day," Kyrgios said. "I'm doing everything I can, I guess."In later games, Juan Martin del Potro withstood 24 aces from John Isner to knock off the big-serving American 7-5, 7-5. Del Potro, a 2009 finalist at Montreal, broke Isner’s service while tied at 5-5 in both sets to advance. Isner had been red hot after capturing back-to-back tournaments in July. “I got lucky to win tonight,” Del Potro said. “Hopefully I can get another draw in the next tournament because nobody wants to play against John in the first round.” Roberto Bautista Agut rolled past Tim Smyczek 7-6(4), 6-1, while American Jared Donaldson, 66th in the world, provided the first upset of the tournament by knocking out French 13th seed Lucas Pouille, twice a title winner this season, 7-6(5), 7-6(8).With inputs from agencies
