A scrappy over continues as De Kock fails to gather a routine throw, the ball hits the stumps and ricochets away for an overthrow. Were De Kock not keeping wicket, I think the skipper might be sending him away to field in the naughty corner for a couple of overs.

It's going to be the snickometer - "Ultra Edge" for this series - which will determine whether this is out or not. But there's not a glimmer on the flatline display, and Hales survives.

So, De Kock has now wasted both South Africa's reviews in this match (batting, when he was blatantly out, and now wicketkeeping). The new Shane Watson?

"De Kock said there was no doubt in his mind that Hales had edged it."

Right. The part-timers have arrived - first up is Farhaan Behardien, whose right-arm medium is strictly of the trundling variety. But keeper Quinton de Kock is convinced that Hales has nicked Behardien's first ball for a catch, and convinces his captain to go for the review...

Garan Jones: I think Hales could become an unbelievable limited-overs batsman. One of the best, but not a Test player.

Tahir is still serving up the occasional low full toss which England could be punishing, but for now they're happy to help themselves to five singles from the bearded spinner. Hales can't quite get hold of the last ball, clearly eyeing up the mid-wicket boundary for six but only earning a single.

Tom: Batting like this makes you wonder why they dropped Taylor. Should always be a place for him in a team.

Morkel gives South Africa a bit more control at the Park Drive End. Just the four bowlers used so far - they'll need to use part-timers to make up the fifth bowler's allocation. Two singles take England to the landmark of 50, Root is trying to show a little acceleration but he's not quite timing it as fluently as we know he can.

"South Africa have used Imran Tahir to pick up lots of wickets in the middle overs and will be hoping for more of the same on a surface which should suit him."

A mixed bag so far from Tahir - full tosses, long-hops and other deliveries which probably deserved to be deposited in the eponymous Duck Pond at the end he's bowling from. Hales helps himself to four through the covers.

In England, Tahir has played for Middlesex, Yorkshire, Hampshire, Warwickshire and Nottinghamshire. He's one short of equalling Marcus North's record of playing for six counties.

South Africa turn to the leg-spin of Imran Tahir, and Hales skies his second ball high over mid-on... but the Notts man gets lucky as the ball lands between two fielders. Big let-off.

Gary Wilson blasted six sixes in a top score of 45 as Ireland cruised to a five-wicket T20 win over Papua New Guinea in Townsville.

Craig Young, Andy McBrine and Kevin O'Brien each took two wickets as PNG managed just 92-9 in their 20 overs.

Ireland were 30-3 before a stand of 53 between Wilson and Kevin O'Brien (19) helped them to 97-5 in just 12.1 overs.

It was the first in a three-game T20 series between the sides, with matches on Sunday and Tuesday to follow.

Wilson scored his 45 off 33 balls in the one-side affair in Australia.

Morkel tries a bouncer, Hales ducks, the crowd cheers - and the Port Elizabeth band are working overtime, having kept playing all day. Hales moves to 17 from 26 balls with a couple of singles, Root has 11 from 27.

James in Peterborough: How can you call Roy's dismissal an off-cutter? The seam position was straight and it jagged in off the seam. Would have done for most batsmen.

England 39-1 (10 overs)

Not out: Hales 15 (22 balls), Root 10 (25)

Fall of wicket: 20-1 (Roy 14)

Bowling figures: Abbott 4-1-17-1, Rababda 5-0-17-0, Morkel 1-0-5-0.

South Africa 262-7 (50 overs) - De Villiers 73, Duminy 47, Du Plessis 46, Topley 4-50

South Africa won toss

Full scorecard

Rabada stays on for a fifth over - Hales bludgeons a slower ball over the bowler's head for four, but then nearly chops a fuller delivery onto his stumps. South Africa were 52-1 at this stage.

Jack Allum: England started very defensively here. Can't see why - should attack and put pressure back on the bowlers.

"He was born to bowl, not field," TMS's Neil Manthorp said earlier of gentle giant Morne Morkel, who's into the attack for the first time. Just a smear or two of sun cream on his chiselled cheeks. Hales takes a single early in the over as he's done a few times today, he's into double figures. Root also makes double digits as he steps across his stumps and guides a four past the square leg umpire.

"It was important for South Africa to get a good start because the way Hales and Roy batted in Bloem took a lot of pressure off the team."

Hales is proceeding in singles, Rabada is matching Abbott for line and length here, South Africa are keeping it tight with a ring of men saving one and safe to say England won't be winning this one with 20 overs to spare.
