The New Zealand openers, Devon Conway and captain Tom Latham, broke a plethora of records with their 323-run partnership in the Mount Maunganui Test match against the West Indies.
Latham and Conway put on 323 in 86.4 overs for the opening wickets after the former won the toss and opted to bat against the West Indies at the Bay Oval. By the time Kemar Roach dismissed Latham for 137 (246 balls, 15 fours, one six), they had already put on the highest opening stand in the history of the World Test Championship: they went past Rohit Sharma and Mayank Agarwal’s 317.
Conway batted until stumps to remain unbeaten on 178 (279 balls, 25 fours) along with night-watch Jacob Duffy (nine). New Zealand finished the day on 334-1.
