An unbeaten 43-ball 102 from Shreyas Iyer powered India's winning start to the T20I series as the hosts comfortably chased down West Indies' 171 in the opening T20I in Lucknow. Iyer's maiden T20I ton included 6 sixes and 10 fours as India raced to the target in only 14.4 overs, with Ishan Kishan (37* off 27) supporting his skipper in an unbroken 137-run stand for the third wicket to take India over the line. Abhishek Sharma hit a six and two fours off Matthew Forde in the first over, and Sanju Samson hit a boundary off Akeal Hosein, to get India going quickly in the chase. Before getting out to the spinner for a 10-ball 21, Abhishek also got a four from Roston Chase. Samson handed a catch back to Hosein in the next over, leaving India at 35 for 2 in the fourth over. Iyer ensured that the remainder of the Powerplay remained profitable in terms of runs, striking four boundaries to take India to 62 for 2 after six overs. West Indies attempted to slow things down with a few quiet overs, but Romario Shepherd's costly 19-run over was followed by three fours from Iyer and a boundary from Kishan. India needed only 70 more runs in the second half to reach 102 for 2 by the end of the 10th over. Kishan got lucky after Iyer hit a 28-ball fifty because the third umpire thought Forde didn't get his hands under the ball when he took a diving catch at sweeper cover in Shamar Springer's over. Iyer also hit his first six in the same over, going straight to the ground. Iyer's innings kicked off with a six from Springer. The Indian T20I captain then hit a six and a four from Hosein in the 13th over, followed by three sixes and a four from Forde, during which he also got a break. By putting Chase over long-on, he reached his 42-ball century, which was the second-quickest T20I century by an Indian captain after Rohit Sharma's 35-ball effort against Sri Lanka in 2017. India won their 10th T20I in a row with a victory in the 15th over thanks to Iyer's winning single, which Kishan enjoyed from the non-striker's end. Earlier, after being asked to bat, Shai Hope helped West Indies off to a quick start with regular boundaries, including four fours in the second over off Mayank Yadav. Arshdeep Singh ended his stay in the fifth over, ending Kamil Pooran's chances at the other end with a couple boundaries. West Indies suffered further setbacks as Shimron Hetmyer was run-out for 5, and Rovman Powell was bowled by Axar Patel for a duck, with the left-arm spinner ending the Powerplay with a maiden. Hope was spared when a slower ball from Mayank hit the off stump without dislodging the bails. With Sherfane Rutherford for company, the West Indies captain powered the team forward as both dealt in fours and sixes. In the ninth over, Kuldeep Yadav scored two sixes, and in the eleventh over, Axar scored 18, including a six from Rutherford. Hope then scored a fifty off 36 balls, but the innings soon fell apart. Hope fell to debutant Naman Dhir, who also picked up the wicket of Shepherd, while Kuldeep accounted for Roston Chase. Kuldeep's second wicket was thanks to a fine catch from Kishan to send Forde back, and Dhir bagged his third by having Springer caught at deep midwicket. From 107 for 3, West Indies slipped to 135 for 8. Rutherford and Hosein's 36-run stand in the final overs was the reason West Indies scored more than 1700 runs. Rutherford scored a fifty off 31 balls by hitting two fours off Mayank and one more boundary off Arshdeep. Arshdeep gave Hosein a six, Mayank got a four, and Rutherford gave Hosein a six as well. However, Mayank was able to mitigate the damage with Rutherford's wicket. West Indies were bowled out with five deliveries remaining in their innings when Axar took the wicket of Hosein in the final over.
