Ireland 331-8: Joyce 112, Balbirnie 97
Ireland need to hold their nerve and be sensible now. Cusack shows them the way with five neat balls that go for just three before then offering a warning of what can happen if you err as his final ball is whipped away through mid-wicket for four by Williams.

"I like the way Porterfield is going about this powerplay. He could just put his men in the ring but he's trying to swarm the batsmen and put them under pressure."

The Ireland fans are singing again, but they are silenced as Williams launches a short ball from Kevin O'Brien over midwicket for six. Ervine is handed strike and top-edges one just short of the fielder sprinting in from deep square-leg. Williams adds another two from the final ball with a whip to leg.
Taylor's wicket overshadowed Williams reaching his 50 from the first ball off that Cusack over. He is now the senior man with a lot of pressure on his shoulders. He is joined by Craig Ervine. The game was slipping away from Ireland but they are back on top now.

"A very good bit of bowling, a slower ball out of the side of the hand, Taylor didn't pick it - the lack of pace did him completely. That's just the tonic for Ireland. This chase suddenly looks twice the size it was."
Huge wicket for Ireland. the danger man is gone. It is his first real loose stroke as he mis-times another lofted drive and pops it high into the air for O'Brien to run in and claim in the mid-wicket area. Suddenly, what was looking like an achievable target seems much further away for Zimbabwe.
Desmond Cassidy:, external I think Ireland's inadequacies in the bowling department are exposing themselves very vividly..Zimbabwe winning this at a canter.

"Very, very clever batting from Brendan Taylor, he's not letting Dockrell settle at all."
Having shown respect to Cusack, Taylor targets Dockrell and hammers two mighty sixes over mid-on, either side of picking up two with a drive through extra-cover. He ends the over with another hit over mid-on, this time for four. Big over for Zimbabwe - these are very worrying times for Ireland.

"Taylor has played magnificently, but you can see from his shape that he's not the fittest bloke out there. That's when tiredness comes into it, you make a little mistake..."
We are into the powerplay and Ireland decide to bring back their best bowler of this innings, Cusack. He starts really well, with three successive dot balls that lift the required run-rate to 9.00 before Williams pokes one away for a single and then Taylor lofts a drive through cover for two. One final single means the over goes for just four. If Ireland aren't going to get a wicket with a good ball, they need to frustrate these two and force a poor shot.
Tom Mackley: I'm sorry Ireland. You were controlling the game until I tuned in and started watching.
Pakistan recorded their third successive victory with an unlikely 29-run win over South Africa in a rain-reduced Pool B match in Auckland.
South Africa's target was revised to 232 from 47 overs but, although star batsman AB de Villiers made 77, he was the ninth wicket to fall as his team were all out for 202.
Left-arm seamers Rahat Ali, Mohammad Irfan and Wahab Riaz took three wickets apiece.

"Taylor has been magnificent; he hasn't put a foot wrong. I can't recall a false stroke."
The run to bring up his hundred is almost Taylor's last as he goes down to sweep Dockrell's last ball, misses and is greeted by a huge appeal from the Ireland players. It is given not out on the field but Ireland review it and are dismayed when Snicko shows that no contact was made with either bat or glove.
What a superb knock this has been from Taylor. He brings it up with a flick towards short fine leg.
Alan Lewis
Ex-Ireland captain on BBC Test Match Special
"The game is so evenly poised at the moment. Ireland really need a wicket."
Stirling bowls and Taylor opens his shoulders and smashes the second six of his innings, which just beats the outstretched hand of the diving Mooney. He follows this up with a four over mid-off, two from a top-edged sweep and a single. The charge is on and Taylor is leading it.
