Top seed Stanislas Wawrinka has lifted his second Chennai Open Tennis trophy. In the final at Chennai on Sunday, the Swiss star recorded a convincing win over Frenchman Edouard Roger-Vasselin. World number eight Wawrinka won in straight sets 7-5 6-2. The match lasted one hour and 35 minutes. Wawrinka had earlier won his first Chennai Open title in 2011. The Swiss star has now lifted five ATP World Tour titles. Roger-Vasselin was trying to win his first ATP title but going past an opponent, who came into the tournament after a phenomenal season, was more than a difficult job.
