Opener Lokesh Rahul's crisp 50 off 65 balls came after the visitors lost Shikhar Dhawan and captain Virat Kohli cheaply.Earlier, the hosts won the toss and decided to bowl first. West Indian teenage paceman Alzarri Joseph enjoyed a dream debut and claimed 2 wickets for 38 runs. India lead the four-test series 1-0.
