Indian rowers Swarn Singh Virk along with Manjeet Singh and Sandeep Kumar yesterday booked berths in the upcoming London Olympics after winning their individual events in the Asian Olympic Qualifiers at Chung Ju, Korea. Virk qualified in the men's single sculls (M1X) while Manjeet and Sandeep made the cut in the lightweight men's double sculls (LM2X) after staving off stiff competition from the other Asian giants. London will be Manjeet's second appearance in the Olympics, having rowed in the same event at the Beijing Games in 2008. This is the fourth time in a row Indian rowers have qualified for Olympics.
