Macartney's batting style — open stance, wristy pulls and cuts, and an air of complete disdain for the bowler — earned him the Sydney crowd's nickname 'The Governor-General' from his Trent Bridge 345 of 1921 onward. The nickname survived him into multiple cricket histories. The most-quoted of his on-field remarks came in the Headingley Test of July 1926. Walking in at 1 for 1, he was dropped second ball at slip off Maurice Tate by Arthur Carr.
The story, related by Tate himself in a 1934 magazine piece, was that Macartney turned to Carr and said something like, 'That's torn it.' Tate's version of the rest is well-known: Macartney scored 100 before lunch, finishing with 151 in 172 minutes. Whether or not the exact phrase was used, the substance — that Macartney took the dropped catch as a personal insult and proceeded to demolish the bowling — is supported by every contemporary account.
Macartney's persona was as much part of his cricketing reputation as his batting average. Wisden, in his Five Cricketer obituary in 1958, said: 'He was the most arrogant batsman of the inter-war period, and his arrogance was justified.' Charlie Walters, his 1920s Sydney club teammate, said: 'When he had bat in hand he honestly believed he was the best in the world. And when he had bat in hand, he generally was.'
