Michael Gough gives Trott out lbw to Johnson. Hitting everything, but Hawk-Eye shows the ball pitched just outside leg stump and Trott's use of the DRS is vindicated. Fine over from Johnson, though, whose form in these games coupled with Mitchell Starc's injury woes might just be significant for the Ashes.
Couple of singles off McKay before Root scampers two after dabbing the ball to third-man off the outside half of the bat. Last ball of the over jags past the outside edge.
Joe Root off the mark with a single to third-man. England in trouble here, losing wickets after the toss in a game likely to be shortened by rain. Duckworth and Lewis are not kind to teams that lose wickets.
Not KP's best day. Fast short ball from Johnson is on Pietersen too quickly, and he miscues a hook shot straight to Bailey at square-leg off the splice of the bat. Simple catch, and both England's openers are gone.
Trott edges McKay past the solitary slip for two runs, Johnson doing the fielding, before a flick through square-leg brings two more. Trott trotting along at a run a ball here, a trait that continues with an easy single behind point. Tidy enough start for England now after all that unpleasant nonsense in the first over.
Trott on his merry way, clipping Johnson through the legside when the left-armer strays too straight. Two runs for that, with a wide down the legside and a tip-and-run single for Trott adding to the total.
Big lbw shout against Pietersen shouldering arms to McKay. Aleem Dar says no. It's coming back enough but going over the off bail. Good judgement all round, with Clarke resisting the temptation to review. Pietersen works to leg for a single before a horrible wide outside off stump is compounded by a miss from Wade behind the stumps to bring England five wides. Trott picks up a single for a dab to third-man.
Mitchell Johnson with the other new ball. Watching the run out shamozzle again, while KP was probably wrong in thinking there was a run there Carberry's indecision was fatal. Needed to either run or give a clear, early "No!" Did neither. Pietersen gets a single off the inside edge before Johnson swings a wide down the legside and Jonathan Trott gets off the mark with two to long-leg.
Before running his mate out, Pietersen had played a glorious shot through midwicket for four.
Shambles. Last ball of Clint McKay's opening over, and Pietersen wants a strike-pinching single. It's never on, and Carberry stands where he is before belatedly, forlornly trying to get to the other end before McKay removes the bails. He's no chance. Done up good and proper.
England decide to go for the old same team, different performance tactic in the face of criticism that their team is a specialist bowler light with only two frontline seamers.
MA Carberry, KP Pietersen, IJL Trott, EJG Morgan (capt), RS Bopara, JC Buttler (wk), BA Stokes, JE Root, JC Tredwell, WB Rankin, ST Finn.
AJ Finch, SE Marsh, SR Watson, MJ Clarke (capt), GJ Bailey, AC Voges, MS Wade (wk), JP Faulkner, MG Johnson, CJ McKay, JR Hazlewood.
England are unchanged, Australia bring in Josh Hazlewood for Fawad Ahmed.
Michael Clarke decides to bowl first after winning the toss, and concedes that's due to the conditions overhead rather than underfoot.
The game's been delayed. There's a finite window of opportunity here before rain returns. Everybody's ready to go. But that toss will not take place before 2.05pm on the dot. When the game falls an over short of being completed later, these five minutes of faffery won't be at all annoying. Cricket's a silly thing sometimes.
Good news. We'll have a toss at 2.05pm followed by a 2.20pm start. Usual "unless there's anymore rain" proviso in place.
Still plenty of naughty-looking cloud overhead at Edgbaston. The shortest game available to us today is 20 overs per side.
More promising signs now, with the covers slowly coming off and both sets of players milling about on the outfield.
No cap presentation in England's team huddle earlier, so we can probably rule out a debut for either Jamie Overton or Chris Jordan today if/when we get some cricket.
"Absolutely rancid." That's the succinct two-word summary of the current conditions at Edgbaston from a brolly-wielding Mike Atherton out in the middle. Hard to argue. Rain still falling right now, so at the very least we have a delayed toss in the "third" one-day international of this sodden series.
