But Powell and Shai Hope (32) together forged a 65-run partnership for the second wicket and took West indies past the 80-run mark. Just when things seemed good in the middle for the Windies, opener Powell (51) was dismissed by Khaleel Ahmed in the 15th over. In the next over, Samuels was also sent packing by Yuzvendra Chahal.Hetmyer then arrived in the middle and stitched crucial partnerships with Rovman Powell and Jason Holder (38) before getting out in the 39th over.Holder also played sensibly before getting out and towards the end, Bishoo and Roach forged a 44-run partnership for the ninth wicket to guide West Indies to a challenging total.For India Chahal took three wickets, while Shami and Jadeja took two wickets each.Brief scores: 322/8 (Shimron Hetmyer 106, Kieran Powell 51; Yuzvendra Chahal 3/41) against India.
