New Delhi: World number two Caroline Wozniacki powered past Russia`s Ekaterina Alexandrova 6-2 6-2 to reach the second round of the Istanbul Cup on Tuesday. Denmark`s Wozniacki was barely troubled by world number 101 Alexandrova as she converted five out of six break points to win her first claycourt match of the season in 68 minutes. The reigning Australian Open champion, back in Istanbul after four years, next meets the winner of Wednesday`s match between Kirsten Flipkens and Sara Errani. "It was tricky, for sure," Wozniacki said. "The first match on clay is never easy, but I`m happy with the win. It`s great just to get a match in and feel better with the movement. It`s all about fine-tuning in matches like these.
