New Zealand captain Kane Williamson hit the highest Test score of his career on Friday with a majestic 251 as the hosts posted an imposing 519-7 declared on Day Two of the first Test against the West Indies here on Friday.

West Indies bowler Kemar Roach said Williamson's innings was one of the best he'd seen as the 30-year-old surpassed his previous record of 242 against Sri Lanka nearly six years ago. In reply, the injury-hit West Indies were 49 without loss with John Campbell on 22 and Kraigg Brathwaite on 20 after cautiously negotiating the 26 overs to stumps.
