Trent Boult's seven for 34 helped New Zealand conquer the second one-day international (ODI) against West Indies by 204 runs at the Hagley Oval cricket ground in Christchurch, on Saturday. Boult's career-best skittled the tourists for just 121 runs, clinching their three-match series with a game still to play. Lockie Ferguson took the remaining three wickets for just 17 runs. West Indies had a dismal start to their chase of a humongous 326 set by the Kiwis. In the absence of star batsman Chris Gayle, who withdrew from the match with an unspecified illness, Windies were immediately in trouble when Boult ripped through the top order. The West Indies struggled throughout their reply with Shai Hope's 23 and Ashley Nurse's 27 being their best performers with the bat. Windies played strong to reduce Kiwis to 186 for 5 in the 33rd over, but they let off the sixth-wicket pair, Henry Nicholls and Todd Astle, that turned the game. The pair kept the scoreboard ticking and went to add 130 runs off 108 balls. The third and final match in the series will be at Hagley Oval on Tuesday.
