9.54amThat was a good toss to win for Eoin Morgan. This pitch looks like it will benefit the chasing side today. For the first time in this series, there is a tinge of green on the wicket, which should provide grip and lateral movement.
9.57amEngland's team is unchanged from Edgbaston, while Australia bring debutante Nathan Coulter-Nile in for Josh Hazlewood.
10.03amWEATHER WATCH: The sun is out and, judging by the sky, it will be here for most of the day in South Wales. We should get a full day's cricket and therefore a result.
10.06amEngland skipper Morgan speaking to BBC Sport: "There's plenty of moisture around so we're going to have a bowl this morning and try to take advantage of the conditions. It's the same team, which is quite encouraging and shows a bit of consistency and can hopefully instil some confidence in the lads. It's a huge opportunity for the young guys coming through."
10.09amAustralia's Michael Clarke: "I probably would have fielded. The wicket looks like it's got a bit of moisture in it, but either way when you bat, you've got to bat well. After what happened in the Test series we've got a lot to play for."
10.12amIt will be interesting to see how Mitchell Johnson bowls today. When he gets it right, he can be devastating. Morgan warned his troops about the left-arm speedster earlier this week.
10.14amAustralia are batting first though. Steven Finn will begin for England, bowling to Aaron Finch. Shaun Marsh is the other Aussie opener.
Aus 1-1Finn starts with a wide on the off side. However, he quickley straightens up and, with his next delivery, he removes Finch lbw. No complaint from the man that hit a record-breaking 156 off 63 balls in last month's T20 at the Ageas Bowl. Great start for England.
Aus 3-1Finn completes the opening over with another wide and a leg bye. Shane Watson is in at number three.
Aus 5-1Shane Watson gets Australia's first runs off the batt as he benefits from a thick edge when trying to drive Boyd Rankin. Marsh also sneaks a single as Rankin's first over goes for two.
Aus 11-1Australia sprint through for a quick single (leg bye). Finn then pitches one up to Watson, who frees up his shoulders and slices high over point for FOUR. Watson gets another single. Six off the third over.
Aus 11-2Rankin gets rid of the dangerous Watson with the final ball of a terrific maiden over. The 29-year-old from Londonderry finds the edge of Watson's flashing bat, providing Jos Buttler with a straightforward catch. Captain Clarke is in at four.
Aus 15-2Finn over-pitches to Marsh, who cracks a straight drive down the ground for FOUR - his first boundary of the day. The bowler the makes an impressive comeback with five successive dots.
Aus 19-2Another tidy over from Rankin produces just four runs. Six overs gone and Australia's run rate is 3.17.
Aus 23-2Marsh looks in good nick as he shows smart footwork before pushing Finn down the ground for FOUR - the only runs of the seventh over.
Aus 27-2Clarke gets lucky as he top-edges an ugly hook shot for FOUR off Rankin. Finn, whose dive failed to prevent the boundary, then loses the ball, which, after a lengthy search, is recovered from some plastic tubing. Four off the over.
Aus 29-2Finn's fine spell continues as Marsh's well-placed cover drive for two is the scoring delivery of the ninth over.
Aus 31-2Clarke is all action right now. His technique and timing are leaving a lot to be desired though. The Aussie skipper cuts into the covers for a tidy two. However, he then swings hard and misses a pacy Rankin delivery, which just misses off stump. The powerplay ends with Australia two down and going at just over three an over.
Aus 41-2A change of bowling sees Ben Stokes come into the attack. His first over goes for 10 - all to Marsh (.24..4).
Aus 50-2Another good over for Australia, who have accelerated their rate to 4.17. Clarke middles a pull shot off Rankin for FOUR. He then works a single to give the strike to Marsh, who cracks one through midwicket for another FOUR.
Aus 51-3Stokes has his first international wicket thanks to an aggressive bouncer. Marsh tries a pull shot, but he gloves to Buttler, who takes a terrific high one-handed catch. George Bailey is in at five. Brilliant second over from Stokes goes for just one.
Aus 57-4The 14th over starts well for Australia as Clarke hits his third FOUR of the innings and then works a tidy two. However, the third ball sees him given out lbw to a straight, but fairly high, delivery from Finn. Clarke understandably reviews, but DRS says that the ball would have just clipped the bails. Umpire's call stands and Australia are four down.
Aus 57-4That is a big blow for the tourists, who will have wanted Clarke to have been at the crease when James Tredwell's spin was introduced. However, the skipper's controversial dismissal sees Adam Voges enter the action.
Aus 57-4Stokes piles the pressure onto the two new batsmen with a maiden over.
Aus 59-4Finn comes up with five successive dot balls, but England are denied back-to-back maidens as Voges tucks the final delivery behind square leg for two.
Aus 61-4Bailey gets off the mark at the 11th attempt. His two are the only runs in the 17th. After starting his spell by going for 10, Stokes now has figures of 1-13 from four overs.
Aus 67-4Voges gets Rankin's last ball of the 18th over away to long leg for FOUR. That was the first boundary in five overs.
Aus 68-4More brilliant bowling from Stokes, whose fifth over goes for just one.
Aus 71-4Yesterday's rain in Cardiff denies Bailey his first boundary, as his pull shot off Rankin plugs in the soft out field. He runs three, which is all Australia can muster from the 20th over.
Aus 73-4A wide and a single is conceded off Stokes. Ravi Bopara is about to be introduced into the England attack.
Aus 75-4Tidy start by Bopara, whose first over goes for just two. Morgan then decides that it is time for a bit of spin. Here comes Tredwell.
Aus 78-4Tredwell's eight overs at Old Trafford cost England 60 runs. However, I would be amazed if he was that expensive today. Voges and Bailey will want to attack the Kent captain once they get set, but for now they look a little tentative. The spinner's first over goes for three.
Aus 82-4Bopara concedes four (21...1). 31 runs have now been scored since Australia's fourth wicket fell.
Aus 92-4Bailey takes on Tredwell and is rewarded with the game's first SIX, straight down the ground. The 25th over goes for 10 and Australia continue to rebuild nicely.
Aus 99-4Seven runs are yielded from Bopara's third over, including an edged FOUR from Voges.
Aus 106-4Australia bring up the 100 with a single of the first ball of Tredwell's third over. There are no boundaries or dots in the over, which goes for seven.
Aus 107-4Bopara contributes a tidy over to tighten things up. Five dots are followed by a single from Voges, bringing up the fifty partnership off 87 balls.
Aus 118-4Bailey smashes a huge SIX over long-on as Tredwell goes for 11 - the biggest over of the match so far.
Aus 124-5With the final delivery of the 30th over, Bopara removes Voges when the batsman's attempted pull shot misses and the ball hits the top of off stump. Matthew Wade is in at seven.
12.30pmBREAKING NEWS - Zimbabwe beat Pakistan by 24 runs in Harare to secure their first Test win over any side other than Bangladesh since 2001.
Aus 127-5Back in Cardiff, Wade gets of the mark with a hurried single of Tredwell.
Aus 128-5More good stuff from Bopara, who goes for just one - a single to Bailey.
Aus 142-5I was wrong - Tredwell is getting the treatment again today, leaking 48 runs off six overs. His sixth costs 14. It starts with Bailey's third SIX, followed by a sweep for FOUR and then a two which brings up his 50 off 57 balls. The over ends with another two, which almost sees Bailey run out, but poor glove-work from Buttler gives the Aussie a second life.
Aus 153-5Wade hits his first FOUR of the day as Australia rack up 11 off Bopara to go into the drinks break with a bit of momentum in their favour.
Aus 153-5Australia take the BATTING POWERPLAY ahead of the 35th over.
Aus 160-5Morgan responds by bringing Stokes back into the attack. The over goes for seven.
Aus 164-5Finn also returns and keeps his figures tidy (2-29), costing just a couple of singles and a two in his eighth over.
Aus 169-5Australia continue to show caution in the powerplay. Stoke restricts the tourists to five in over 37.
Aus 177-5Wade cracks Finn over extra cover for FOUR and then works a single, leaving him on 21 off 24 balls. Bailey, who started the over with a single, finishes it with a two.
Aus 177-5Australia's run rate is now 4.66. If they bat out the remaining 12 overs at the same rate then they will finish on 233, which wouldn't be far off par. The tourists will be expecting to get a few more than that though and they are rightly slight favourites to win at present.
Aus 192-5Bailey's fine form continues as he hits Stokes for three FOURS. He is now on 80 off 77, while Australia's run rate has jumped to 4.92.
Aus 195-5Bopara goes for just three. Sixth bowler Joe Root is now coming into the attack. These batsmen probably won't have seen too much of Root with the ball. Perhaps Morgan is aiming to unsettle them with the element of surprise?
Aus 204-5Australia surpass 200 as Root goes for nine.
Aus 209-5Five singles and a dot from Bopara, whose economy rate is now 4.44 after nine overs. Morgan's experiment with Root appears to be over - Tredwell is returning to the attack.
Aus 210-7James Faulker comes in at number eight and, after two dots, he works a single to give Bailey the strike. Bailey then pushes hard on the final delivery in an attempt to retain the strike, but Faulker fails to get home in time and Buttler whips off his bails.
Aus 216-7Mitchell Johnson is the new man at the crease. He gets off the mark immediately, but Bopara goes for just five in his final over, ending with handy figures 1-45.
Aus 218-9Australia have lost their dangerman and they are collapsing in spectacular fashion. Bailey, who had dragged his side back into the ascendancy with a meaty contribution, including five fours and three sixes, feathers one through to Buttler, who does very well. Bailey faced 91 balls. Tailenders Clint McKay and debutante Coulter-Nile are now at the crease.
Aus 225-9Coulter-Nile finds the boundary for FOUR, but Finn's 10th and last over only goes for six, leaving him with figures of 2-43
Aus 226-9Coulter-Nile's edged single is all Australia can muster from Rankin's final over. The Northern Irish-born bowler finishes with 2-31.
Aus 227 all outCoulter-Nile, who ends unbeaten on seven, takes a single off Tredwell. McKay then advances and tries to attack the bowler. However, he misses the ball, which flicks off his pads and rebounds onto his stumps. Australia are all out with 10 balls of their innings unused.
2pmEngland will need to go at 4.56 runs per over to win today. The hosts are certainly the favourites, but Australia are far from out of this match.
2.02pmThe players are taking lunch and so am I. See you in around 30 minutes.
2.27pmEverybody is refuelled and England's chase is about to get underway. Carberry and Kevin Pietersen will open for the hosts. McKay to bowl the first over. 228 required.
Eng 6-0Carberry gets off the mark straight away with a single. McKay then bowls a wide, before serving up a leg-stump half volley, which Pietersen smacks away for FOUR. Four dots follow, including a delivery that catches KP on the box. Painful.
Eng 8-0Solid start from Johnson, whose first over costs just two singles.
Eng 8-2Jonathan Trott is out for a golden duck. He foolishly chases a wide ball and edges to Finch at second slip. Trott now has two little ducks in this series and England are struggling. McKay on a hattrick. Root is in at four.
Eng 8-3WICKET - ROOT (0) C WATSON B MCKAY - HATTRICK
Eng 8-3Root nudges at another full delivery and edges straight to Watson at first slip. McKay, who still has three balls remaining in this third over, is mobbed by his teammates. He has just become the fifth Australian bowler to claim an ODI hattrick.
Eng 8-3Captain Morgan comes to the crease and plays out three dot balls to complete a magical over for McKay.
Eng 16-3Johnson's second over goes for eight courtesy of a wide, three singles and a FOUR from Morgan through the covers.
Eng 16-3McKay is on fire right now. He serves up another maiden over. Carberry blocks two, leaves two and mistimes two.
Eng 21-3Morgan tickles down to long leg for a single. Johnson then provides Carberry with a full delivery on off stump and the batsman times his shot nicely down the ground, past mid-on for FOUR.
Eng 25-3McKay's fourth over goes for four as Morgan's inside edge earns two. The England skipper flicks and misses at a wide, before taking a single off a block to point. As has become custom, Australia then waste their REVIEW by appealing for a caught behind. Morgan's bat was not even close to the ball.
Eng 26-3Faulkner replaces Johnson at the River End and concedes just one off his first over, as Morgan's thick inside edge skids behind square for a single.
Eng 26-3A third maiden for McKay - this time bowling at Morgan.
Eng 26-3Faulkner follows suit. The mandatory powerplay is over and England have had a torrid time. Australia were 31-2 at this stage.
Eng 30-3After 14 scoreless shots, England finally add some much-needed runs as Morgan strikes a clean on-drive for FOUR. McKay's sixth over comes to an end. He has cost just 14 runs so far.
Eng 34-3Carberry dances down the wicket and dispatches Faulker down the ground for FOUR.
Eng 35-3Watson comes into the attack and bowls a tidy opening over, which goes for one - Morgan's thick outside edge down to third man.
Eng 37-3Clarke continues to rotate his bowlers, giving Coulter-Nile a first international over. The 25-year-old debutante starts well, conceding only a couple of singles.
Eng 40-3Watson and Coulter-Nile keep it tight again, conceding one and two respectively in their second overs. England's run rate is a slow 2.5 after 16 overs, but Carberry (13) and Morgan (17) are building a useful partnership - currently 32.
Eng 41-3APPEAL! Watson, whose team has already wasted their review, is convinced that he's got Carberry, who appeared to glove to Wade. Umpire Rob Bailey says no - and he is proven right! Replays show that the ball hit the batsman's shoulder. Morgan's single is the over's only run.
Eng 43-3Coulter-Nile goes for just two, as England's required run rate rises to 5.78.
Eng 50-3England reach 50 in the 19th over by taking seven off Watson. The highlight of the over was Carberry's lofted one-bounce FOUR through mid-off.
Eng 51-3Coulter-Nile calms things down again, conceding a single to Carberry before registering five dots at the expense of Morgan.
Eng 57-3McKay returns and piles pressure on Carberry with four consecutive dots. However, the batsman finishes the over well, following a well-placed two with a flat FOUR through the off side.
Eng 61-3Morgan dabs Johnson to point for one. Carberry then cracks beyond extra-cover for a couple, before clipping through square leg for another single. England require 167 runs from 28 overs.
Eng 76-3Big over for England - and it comes off the bowling of McKay! Carberry kicks things off with a simple single. Morgan then smashes three FOURS and a two to inject some momentum into this chase. At the corresponding stage in their innings, Australia were 78-4. Game on? I think so!
Eng 79-3England take three off Johnson. The partnership between Carberry (28) and Morgan (41) is now worth 71 runs off 21.3 overs.
Eng 84-3The hosts continue to build steadily, taking five singles off Faulkner.
Eng 89-3Johnson bowls two dots to Carberry. Clarke then decides to move Watson from midwicket to slip. Carberry exploits the positional change by swivelling and playing a controlled shot for FOUR. Another pair of dots are followed by a single to end the over.
Eng 95-3Australia position two men at point and Faulkner bowls the ball well wide of off stump in an attempt to get Carberry to take a risk. He does, taking the aerial route, but he finds the gap and gets two. England take six off the over and continue to accumulate steadily.
Eng 97-3Coulter-Nile returns for Australia and is economical once more. The lad doesn't look like taking a wicket though.
Eng 101-3England's 100 comes up after 28.4 overs as Carberry sneaks a single off Faulkner, whose over eventually goes for four.
Eng 107-3Carberry hammers Coulter-Nile between deep point and third man for FOUR. He then gets a huge slice of luck, as an inside edge just misses his stumps. The 30th over ends with Carberry and Morgan both just one run short of 50.
Eng 108-3Carberry reaches 50 by guiding another single to third man off the first ball of Watson's fifth over. That's the 32-year-old's first international half century in any format.
Eng 112-3Morgan surpasses 50 with FOUR, getting on the front foot and timing a sweet cover drive to the boundary.
Eng 126-5Carberry starts the over well, scoring six off the first five deliveries, but he is finally dismissed when he walks across his stumps, beyond the ball, which flicks off stump. He faced 95 balls and hit seven fours.
Eng 127-5Buttler comes in for Carberry and plays out five dot balls to Watson, while Bopara sneaks a single. Here comes the BATTING POWERPLAY.
Eng 133-5Bopara clips Coulter-Nile to backward square for one, before Buttler plays a glorious stroke, nailing a cover drive through the infield for FOUR. He then finishes the over with a rushed single.
Eng 139-5REVIEW! Watson raps Buttler's pads and the umpire's finger is raised. However, England challenge the decision, which is overturned when DRS shows that the ball was sliding down the leg side. England take six off the over (31..11).
Eng 141-5Bopara gets lucky again. He edges Coulter-Nile towards Wade, but the ball drops just short. Tight over from the debutant though - just two from it.
Eng 144-6Bopara's poor 19-ball innings is brought to an end as he drives at and misses a straight one. Stokes is in next. England need 84 runs from 68 deliveries.
Eng 149-6Stokes gets a single first ball. Faulkner then concedes FOUR byes as the ball flicks off Buttler's pads and trickles to the rope.
Eng 159-6Good over for England, who take 10 off Johnson (12214.).
Eng 167-6Buttler's fourth FOUR of the match, an uppish drive through mid-off, is the highlight of the 41st over, which sees Faulker leak eight runs.
Eng 175-6England take another eight off Johnson (1111.4) and they are well in control of the run rate, which is 6.62. Both batsmen are nicely in. They just have to hang around for a little longer.
Eng 189-6The home fans can sense the finishing line as Watson is attacked and goes for 14 (224411). Buttler has raced to 39 off 32, while Stoke is on 14 off 10. The required rate is just 5.57.
Eng 192-6Good over from Faulkner - just three more runs to Stokes. England need a run a ball off the last six overs.
Eng 196-6Watson makes a strong comeback, going for just four, but Australia need a wicket.
Eng 205-6Faulkner restricts England to two from the first four balls of over number 46. However, Buttler then middles a huge SIX into the river. A replacement ball arrives and Butter clips it away for one. 23 from 24 is what's needed.
Eng 205-6McKay was the Australian hero earlier in the innings when his terrific hattrick removed Pietersen, Trott and Root, leaving England 8-3. He might just have to produce some more heroics to prevent the hosts from levelling the series at 1-1. Here he comes to bowl his ninth over. His first eight went for 35.
Eng 210-6Five come off McKay's ninth over. England need 18 off 18. Johnson is coming back now. He has a bit of a reputation for crumbling under pressure. Let's see what happens...
Eng 215-6Buttler blots through point for a single, before Stokes defends a short one for no run. Johnson tries another short one and Stokes gives it the treatment, whacking it over mid-on for FOUR. 13 needed off 15.
Eng 219-6Stokes capitalises on a misfield to scramble home for one. Buttler then slugs one into the leg side for another single. The final ball of the over produces a wide, followed by two through square. Nine from 12 is the equation.
Eng 219-7The first ball of the penultimate over produces McKay's fourth wicket. Stokes walks off the field shaking his head, having been mistimed his shot awfully.
Eng 221-7Tredwell replaces Stokes and fails to scores off his first three deliveries. However, the spinner then nudges a single, before Buttler scrambles through for one. He retains the strike for the final over. Johnson to bowl. England need seven to win.
Eng 227-7MASSIVE SIX from Buttler with the first ball of the final over. Scores are tied. England need one from five.
Eng 231-7Buttler strikes FOUR down the ground and ENGLAND WIN BY THREE WICKETS with three balls to spare.
6.15pmBrilliant innings by Buttler, whose 65* off 48 takes England over the line in Cardiff. These two nations will now meet at the Ageas Bowl on Monday to decide the series. Be sure to join Sports Mole for that one. Goodbye for now.
