Brydon Carse peeled himself off the outfield at the Gabba with his shirt drenched through with sweat, his left hand strapped, and his whites stained with grass after a failed attempt at a sliding stop on the boundary rope. His obvious exhaustion reflected England's mood: through no shortage of effort, this series is already threatening to slip away from them.
England simply cannot afford to lose in Brisbane. If that sounds like an exaggeration after four days of cricket, consider this: only once, in 1936-37, has a team ever come from two-nil down to win an Ashes series. They have been handed two golden opportunities to face an Australia side without two of their three great fast bowlers but gifted them a win in the first Test and already have conceded a significant deficit in the second.
They still have a foothold thanks to Australia's crazy half-hour under lights, but make no mistake: this was a brutal day for England, who leaked more than five runs per over, dropped five catches, and rarely managed to hide their frustrations in doing so. Carse personified their struggles, his eye-watering figures of 3 for 113 from 17 overs somehow representing a comeback from a dreadful start.
Mark Waugh, commentating for Fox, described Carse's pitchmap as "third-grade standard" during his first spell, then apologised to third-graders who might think that was an overly generous assessment. He seemed convinced that Jake Weatherald and Travis Head had weaknesses against wide long-hops and straight half-volleys, being picked off either side of the wicket, and leaked 45 runs in his first five overs.
In the twilight, Carse could be seen cursing himself at mid-on as Ben Stokes ran in after an over that highlighted his volatility: he struck Steven Smith on the right elbow with a ball that climbed sharply, but then booted the air in frustration after his wide half-volley was sliced away behind point and felt his body thud into the pitch two balls later, losing his footing in his follow-through.
His third spell lasted a single over. Carse charged in and slammed one in halfway down at 84mph/135kph, and watched Cameron Green back away to slap it, cross-batted, over mid-off for four. Green cut him for four more, Smith top-edged a hook for six, and a loopy bouncer was deemed wide, too high to reach.
Things were getting badly out of hand: Carse's figures after 12 overs - 1 for 95 - were briefly the most expensive in England's Test history. Then came a bizarre, drawn-out over: another loopy wide, a yorker bluff to clean up Green, a drop at gully by a sprawling Ben Duckett, and an outstanding diving effort by Will Jacks at long leg to account for Smith.
He charged down to Jacks in celebration, briefly convinced that his and England's day to forget was becoming a night to remember. But it soon came crashing back down: in between drops by Duckett and a tough chance for Joe Root, Carse shelled the easiest of the lot at cover to reprieve Michael Neser and split the webbing on his left hand in the process.
It was nearly as tough for England's other bowlers: Stokes leaked 5.47 runs per over and struggled with cramps, Jofra Archer had two catches put down off his bowling, Will Jacks' only over cost 13 runs (including four byes for a freebie down the leg side), Gus Atkinson is wicketless after 39 overs in this series, and Mark Wood's left knee is in a brace.
Since bowling Australia out for 132 in Perth - the best-case scenario for their fast but fragile attack - England have conceded a combined 583 for 8 in 101.2 overs and appear incapable of exerting any control. Stokes must shoulder some of the blame: unusually, it was hard to ascertain England's plan to take wickets for much of the second day in Brisbane.
There has long been a sense within English cricket that Carse is ideally suited to bowling in Australia. He took wickets in the Lions' win against Australia A at the MCG in 2019-20, made a strong impression before an injury while bowling to England's batters in the build-up to the 2021-22 series, and is rare in preferring the Kookaburra ball to the more familiar Dukes.
He is their leading wicket-taker in the early stages of this tour, but that he has also conceded more than a run a ball is emblematic of England's wider selection policy: picking players based on their best moments with minimal concern for their consistency results in days like these. For all the adrenaline and excitement England have produced, Australia are in control.
"Clearly we didn't get it right to start with," Root said, doing his best to cling to the positives, "but the way we responded, especially towards the back end of the day [was great]…The wheels could have come off and at other times - probably on a tour where I was captain, they would have.
"We know that [when we play] our best cricket and when we execute well, we're a very difficult side to play against. It's about turning up with the right manner tomorrow… I don't think we're massively out of the game at all. I think we're actually not too far behind, as long as we get things right early tomorrow."
Root is right that all hope is not lost: England could yet blow away Australia's lower order on the third morning, and will have the opportunity to bowl last on a pitch that has already shown signs of variable bounce. But Carse's slow trudge towards the dressing room was a reminder that another sloppy, error-strewn day could prove terminal.
