TOKYO -- Canadas Milos Raonic advanced to the semifinals of the Japan Open with his 40th victory of the season Friday. Raonic, seeded third, cruised past Slovakias Lukas Lacko 6-3, 6-3 in just over an hour. The 22-year-old from Thornhill, Ont., once again used a dominant serve to beat his opponent, with 11 aces to only two for Lacko. Raonic said taking the early lead was key following an overnight change in the weather. "I felt I started really well, right from the beginning which allowed me to get into the match and continue from there," said Raonic. The quarter-final was played under the closed roof of the Ariake Coliseum after to a cold front moved in bringing drizzle and chilly temperatures. "I felt like I dealt with the conditions well today," said Raonic. "Confidence is a big part of it and helps you in those adjustments to the difference in conditions. "Despite the weather changes from hot and humid to cold and not so humid the court has remained relatively the same -- fast," he added. "But I just felt that I was aggressive through the match and that paid early dividends." Raonic will next face Croatian Ivan Dodig, who defeated Finlands Jarkko Nieminen 6-2, 7-6 (3). Dodig has won two of the pairs three matches, including a second-round victory over Raonic last June on grass at Eastbourne and a Barcelona win in 2011. A win over Dodig would mark a return for Raonic to the Tokyo final where he lost a year ago to Kei Nishikori. "It will be another tough match against Ivan," said Raonic. "Im focused on what I need to do for the next one." Raonic, ranked 11th in the world, is coming off a win at the Thailand Open on Sunday and improved his season record to 40-17. Hes trying to earn one of the last spots in the World Tour Finals in London next month. Raonic never faced a break point against the 81st-ranked Lacko.

He took early control against Lacko with two breaks to earn the first set in 25 minutes. Raonic went up a quick break in the second for a 2-0 advantage, and later closed his match with a service winner. Meanwhile, top-seeded Juan Martin del Potro overcame Alexandr Dolgopolov of Ukraine 4-6, 6-4, 6-2 to reach the semifinals.
