Watson's monster hit, and Roy's impressive leap
Blow of the day
David Warner's innings was abruptly ended first ball when a nasty short delivery from Steven Finn struck him on his left thumb. The physio was quickly in attendance and it only took a cursory inspection before Warner left the field. In the dressing room he took painkillers, then went for a few throwdowns in the Nursery Ground nets with a view to returning at the fall of the second wicket. However, after the Steven Smith-George Bailey partnership was broken, Glenn Maxwell walked out and Warner was not seen again. It was later confirmed to be fracture that would rule him out for up to six weeks.
No-ball of the day
Under the tweaked ODI regulations all no-balls - whether front-foot or not - are awarded a free hit the next delivery. So when Ben Stokes let slip a chest-high full toss at Bailey there was an opportunity to swing hard at the next ball. It did not go quite to plan, though, for Bailey, as he clubbed the ball straight to mid-on.
Edge of the day
Rarely is there discussion about one-day cricket these days without the word "aggression" used at some point. Eoin Morgan was perhaps left wishing he had been a touch more aggressive when Maxwell was new to the crease. Facing Liam Plunkett, Maxwell, on nought at the time, nicked to the left of Jos Buttler at just about the position where a slip would have been stationed. It may not quite have carried - or, of course, might have been dropped - but with a new, dangerous batsman still fresh at the crease and a strike bowler running in it felt like a missed opportunity.
Six of the day
There is much debate about the biggest six ever stuck at Lord's, but the only recorded success of clearing the pavilion remains with Albert Trott in 1899 - although in those days the pavilion was not as high. Since then, a number of players have found the top tier - Kim Hughes launched Chris Old that way in 1980 and in 2009 Kieron Pollard came very close to matching Trott's feat - while in 2010 Marcus Trescothick was offered £1million from a bat sponsor if he could clear the pavilion. Today, the members perched aloft were in danger when Shane Watson got going against Moeen Ali as he bludgeoned a straight drive into a mass of scurrying cricket-watchers amid Australia's late onslaught. A few balls later, the top tier of the Tavern Stand was also located.
Attempt of the day
Mitchell Marsh almost fell to what would have been one of the greatest catches seen on the ground. He could not have struck his skimming cover drive off Chris Woakes any better. Jason Roy, on the cover boundary, had seconds to react, sprinted to his right then dived full-length to reach the ball with one hand. For a moment it appeared he had it, but he could not hold on and to his anguish then saw the ball run over the rope. There was no fault, at all, on Roy, but he stood there with his head in his hands as the fielders changed ends.
Drop of the day
Marcus Stoinis has had a difficult start to his first senior tour with Australia. His single over in the T20 went for 13 and he could not see the side over the line with the bat. He has not been in the XI for the start of the one-day series, but was needed as a substitute fielder due to the injuries to Warner and Shane Watson. In the 12th over he had a chance to make a mark when James Taylor sliced towards third man, but despite the catch coming almost straight to him it was grassed. It's all a learning experience, as they say.
Glove of the day
Until the 26th over of England's chase - and with all due respect to Marsh - this had been a fairly unremarkable one-day international. That all changed when Stokes stuck out his glove, in self-preservation or not depending on your view, when Mitchell Starc hurled the ball back at him and was given out obstructing the field. Boos rang around the normally sedate Lord's as England players glared at the middle. The Twitter world - if these things can ever be used as a judge - was almost split down the middle. It was an incident likely to rumble on for a little while yet.
