Australia won the toss and chose to bat. Archie Jackson edged Maurice Tate to slip in the first over and out walked Bradman. What followed unspooled across 448 balls and 383 minutes: 46 fours, six threes, 26 twos and 80 singles, almost no air-borne strokes, and a relentless milking of Tate, Larwood and Tich Freeman. By tea on day one he had 220; by close 309 not out from 105 overs of cricket. Yorkshire crowds, normally taciturn, stood as he passed Foster, Murdoch and Charlie Macartney's Headingley records.
On the second morning Bradman pushed past Sandham's 325 — the existing Test record set against West Indies in Kingston only a few months earlier — before Tate eventually had him caught behind by Duckworth for 334. Australia made 566. England, despite a Hammond hundred, were forced to follow on at 391, and rain saved them at 95 for 3.
The innings is the spine of the 1930 Ashes legend. Bradman's series sequence — 8, 131, 254, 1, 334, 14, 232 — produced 974 runs at 139.14, a series aggregate that has stood unbroken across the next 95 years of Ashes cricket. He averaged a Test innings every 21 deliveries, a cadence that left selectors and bowlers alike reaching for new tactics. Within two years those tactics would harden into Bodyline.
Bradman himself called the opening day 'the greatest of my cricketing life.' For Yorkshire, who would adopt the small Australian as a kind of honorary native, it began a love affair: he would return in 1934 and score 304 on the same ground.
