In the final two ODIs against the West Indies, the 24-year-old Iyer scored two consecutive half-centuries and played 125 and 120 runs in the second and third ODIs with captain Kohli respectively to help India win the series 2–0. Kohli also scored centuries in both matches.
In the third ODI, Iyer came out to bat when India lost three wickets for 91 runs in the 13th over, chasing a revised target of 255 in 35 overs. He played an aggressive inning of 65 off 41 balls and reduced the pressure on Kohli, who remained unbeaten on 114 runs.
After the third ODI on Wednesday, Iyer said in an interview to Chahal, “I am very happy. I wanted to come to bat only in such a difficult situation when everyone is nervous in the dressing room. I like it because the match can change and the position of the team can change.
