Bernard Tomic and Sam Stosur suffer losses in opening Hopman Cup ties Bernard Tomic opened his Australian summer in disappointing fashion, suffering a straight sets defeat to Canadian Milos Raonic in the opener of the Hopman Cup. Bernard Tomic plays a forehand in the men's singles match against Milos Raonic of Canada during day one of the 2014 Hopman Cup in Perth. BERNARD Tomic was philosophical after beginning his Australian summer with a disappointing straight sets loss to big-serving Canadian Milos Raonic at the Hopman Cup. Raonic, the world No.11, blasted 18 aces as he defeated Tomic 7-6 (8-6) 6-1 at Perth Arena. Tomic conquered then world No.1 Novak Djokovic in an unbeaten singles run at the tournament last summer. But it was a disappointing first Hopman Cup loss for Tomic last night as he lost the second set in just 22 minutes following a dogged first set. Bernard Tomic wipes his face in the men's singles match against Milos Raonic of Canada during day one of the 2014 Hopman Cup in Perth. Sam Stosur also went down in three sets to teenager Eugenie Bouchard to cap a horror night for the Australians. The Aussie pair found some late consolation with a 6-2 6-4 win in the mixed doubles. Tomic, who was playing his first match under new coach Velimir Zovko, said he was still well placed ahead of his title defence at the Sydney International next week. It was good to get out and play that match. Obviously next week is where it counts," the 21-year-old said. It's very difficult to play well in the first match. He has the best serve, for me, in the world right now. There's no doubt about that. His serve was that good and I was struggling to get racquets on it. Tomic was broken in just the third game of the match, but broke back to level the first set at 3-3 before it went to a tiebreak. A nerveless Tomic pulled the trigger with a sensational off-forehand down the line to save Raonic's first set point, but the Canadian closed out the opening set with his next opportunity. Raonic took complete control in the second set, breaking the Australian to love to race to a 4-0 lead before serving out the match. Meanwhile, Stosur's home summer curse continued as the Australian veteran was stunned by rising Canadian star Bouchard. Glamour girl Bouchard, 19, showed off her power game, exploiting Stosur's mental demons as she fought her way back from a set down to triumph 4-6 6-2 6-3. It gave Canada an unassailable 2-0 lead in the tie. Stosur, the 2011 US Open champion and ranked 18 in the world, is burdened by her horror summer 12 months ago and decided to come to Perth in the hope a guaranteed three matches would provide a better lead-up to the Australian Open. The upset loss to Bouchard, the highest-ranked teenager in the world at 32, was not a part of the plan; however, Stosur will have the chance to make amends with further stern tests against Italy's Flavia Pennetta and Polish world No.5 Agnieszka Radwanska to come later in the week. Stosur's previous two visits to the mixed teams tournament, in 2006 and 2010, led to fourth-round appearances at the Australian Open, her best results at her home grand slam. Bouchard broke Stosur when the Australian served at 3-4 in the final set to set up her victory and served out the match on a night when both players struggled to hold. "It was my first match obviously so sometimes things feel a bit rusty and stuff, but it felt good having a good long battle with her and I felt like I improved towards the end of the match," Bouchard said. She has a really good forehand. She likes to run around it a lot and control the point, so I was trying to not let her do that and trying to be the aggressive one and step in and control the point. I think I overall kind of did that well. The young Canadian was crowned the WTA's newcomer-of-the-year in 2013 after her ranking soared from 144 to 32. But Bouchard refused to outline any lofty goals for the Australian Open, despite her star continuing to rise with another top-20 scalp. "I always believe in myself and I think I can do really well, but I have to take it one match at a time," she said. I'm going to use this week and next week as preparation, but also trying to win the matches that I want to win and go into the Australian Open feeling good. Milos Raonic plays a forehand to Bernard Tomic in their Hopman Cup clash. Raonic said he sensed Tomic's level drop off after he lost the tie-breaker. I changed a little bit, but I think it was more him just dropping off a little bit. He made some errors he wasn't making," Raonic said. But I felt like I was also putting on a bit more pressure so it was a little bit here and there. Last night's match was the most significant challenge of the tournament for Tomic, who will play Italy's Andreas Seppi, ranked 25 in the world, on Tuesday and Poland's late call up Grzegorz Panfil (288) on Thursday. Seppi had to withdraw during his singles match yesterday with illness but is hopeful of being fit to play for the rest of the week. Tomic, the highest ranked Australian male at 51, helped Australia back into the Davis Cup World Group but endured a poor ending to 2013 in other tournaments.
