Middlesex 138 for 1 (Stoneman 62*, Holden 24*) trail Glamorgan 620 for 3 dec (Northeast 335*, Ingram 132*, Carlson 77, Root 67) by 482 runs

By the time he marched off in mid-afternoon with 335 not out to his name, out of Glamorgan's towering total of 620 for 3 declared, Northeast had gone higher than any batter at the equivalent stage of any previous county season, and further into Lord's own ancient record-books than any man in more than 200 years of precedent.

More than 2800 first-class fixtures have taken place at Lord's since July 1814, when MCC - having twice moved home in their previous 27 years of existence - christened their ultimate venue with a local derby against St John's Wood, in which neither team made as much as 200 across four innings.

At the age of 34, and having - like the aforementioned Hildreth - come to be regarded as the best batter of his generation not to have earned an England call-up, this performance is unlikely to change anything on that front. And by the close, it might not count for a whole lot more than Glamorgan's handy haul of four batting points. Craig Miles' dismissal of Sam Robson for 43 in the 30th over of Middlesex's reply turned out to be the only wicket that fell all day, as Mark Stoneman's doughty half-century confirmed that the Kookaburra ball would prove to be every bit as truculent for the visitors.

That scarcely detracted from the quality of Northeast's performance, however. The day was only four overs old when a punched single into the covers secured him his first ambition, a second career double-hundred, but it was the moment of his 250, secured with a thumped drive over long-off off Ryan Higgins in the final half-hour of the morning, that truly ignited his mood.

By then, Northeast had survived a second costly miss at backward point - on 239 this time, compared to 11 on the first morning - but there was no question of treating the moment as a cautionary tale. Each his six sixes poured forth thereafter, three off Higgins as he strayed too full in his arc, and three more off the toiling spinner Josh De Caires, including a monstrous mow across the line and over the extra-long Grandstand boundary, some 80 yards up the hill.

De Caires - whose father Mike Atherton had been watching the rain fall at Old Trafford on day one before driving his own parents down to witness their grandson in action - eventually retreated with the bruised figures of 28-0-147-0, including a leg-side long-hop that allowed Northeast to roll his wrists through a pull through backward square and rush on through to that triple-hundred. By then, however, De Caires (and his grandparents) should have had something to cheer with Northeast on 291, only for Jack Davies behind the stumps to make a hash of a regulation stumping.

None of it ultimately mattered, however. As, indeed, might also be said of the remaining two days of a bat-dominant game - though tell that to Stoneman and Max Holden, whose own quests for a statement innings are only just be beginning.
