Opener KL Rahul hit his second test century, powering India to a respectable 319/6 on day 1 of the second test in Colombo. India lost two early wickets of Vijay and Rahane, but a 164 run stand between Kohli (78) and Rahul (108) for the third wicket and Rohit Sharma's third test half-century (79) helped India recover.
