Yorkshire began their second day at 423 for none. By lunch the pair had passed J.B. Hobbs and Andrew Sandham's 1926 record of 428. They pressed on. At what the scoreboard showed as 555, Sutcliffe — who had moved to 313 — deliberately played on, allowing Yorkshire to declare with the world record secured. The crowd swarmed, the players shook hands, and only then did the scoreboard get rechecked: a missed signal had left the total at 554, one short.
A frantic conference produced a solution. Essex were persuaded to allow an additional ball to be bowled with the partnership reinstated; an extra was added to the total to take it to the agreed 555 before the declaration was reapplied. Yorkshire eventually declared at 555 for one, with Holmes 224 not out and Sutcliffe out for 313.
Essex, batting twice, scraped a draw. But the headline number — Yorkshire 555-1 dec — entered the record books and the partnership stood as the world first-wicket record for 44 years until 1976.
