Soeda stuns champion Wawrinka in Chennai Open

Japanese qualifier Go Soeda upset defending champion Stanislas Wawrinka of Switzerland to storm into the semi-finals of the ATP Chennai Open on Friday. The 120th-ranked Soeda outwitted world number 17 Wawrinka 6-4, 6-4 to enter his first semi-final on the tour where he will play top-seed Janko Tipsarevic of Serbia. World number nine Tipsarevic overcame Belgian wildcard David Goffin 6-2, 3-6, 6-2 in a late night match that lasted two hours. The other semi-final on Saturday will feature second seed Nicolas Almagro of Spain against number four Milos Raonic of Canada. World number 10 Almagro saved three match points in the second set and wasted three himself in the third before beating another Japanese qualifier Yuichi Sugita 4-6, 7-6 (10/8), 6-4. Big-serving Raonic blasted 15 aces to oust Israel's number one Dudi Sela 7-6 (7/4), 6-3. Soeda said he was living a dream after winning six matches in a row -- three in the qualifying and three more in the main draw. "I am so excited to be in a semi-final and that too after beating such a high-ranked player," the 27-year-old Soeda said. "Hope I get to play on the centre court now. All my matches so far have all been on the outside court." Wawrinka, who beat Xavier Malisse of Belgium in last year's final, said he was short of confidence at the start of the season. "You win some, you lose some, that is life," he said. "He (Soeda) played really well, but I am not confident enough yet. I am sure I will improve as the season goes on." Sugita was a step away from joining compatriot Soeda in the semi-finals when he secured three match points in the tie-breaker of the second set, but failed to convert any. Almagro seized the chance to win the tie-breaker and then also took the decider, despite wasting three match points on 5-4. The Spaniard, who was given a bye in the first round and earned a walk-over in the second, was delighted to come through unscathed in his first match of the season. "It was tough out there and I am happy to win my first match this year," Almagro said. "I took time to settle down, but he played really well." Raonic, who was named the ATP's newcomer in 2011 after rising from number 156 to 31, was relieved to defeat Sela. "There were lot of things to be happy about, but also a lot of things still to be addressed," the 21-year-old said. "I served better today than in my previous match, but I struggled with my overall game. I was a bit hesitant in deciding when to attack. There was a lot of confusion in my mind." "Hopefully I will do better in the semi-final."
