New Zealand's Devon Conway became just the seventh batsman in Test cricket's 144-year history to make a double century on debut with a score of exactly 200 against England at Lord's on Thursday.
The South Africa-born opener's marathon effort of more than nine-and-a-half hours was the cornerstone of New Zealand's first-innings total of 378.
Conway was in sight of becoming the first player to bat throughout their very first Test-match innings.
But with only last man Neil Wagner for company, he was run out after lunch on the second day of this two-match series, having faced 347 balls, including 22 fours.
But he had still joined an exclusive club, with Mathew Sinclair the only other New Zealand batsman to have made a double century on his Test bow.
Left-hander Conway had already broken the record for the highest innings by a batsman making their career Test debut at Lord's when, on Wednesday, he surpassed the 131 made by India's Souray Ganguly in 1996.
Conway's innings, which ensured a place on the famed dressing room honours board at the 'home of cricket', was also the second highest by a New Zealand batsman in a Test at Lord's behind Martin Donnelly's 206 in 1949.
