The Ireland squad were given the day off in Canberra after a second straight win at the World Cup but National Coach Phil Simmons admits there is plenty of work ahead for the bowlers before the third game against South Africa here on Tuesday.

Simmons pulled no punches despite Ireland following up their four wickets win over West Indies with a two wickets success against UAE on Wednesday, describing the 'death bowling' as "terrible".

"We will sit down, not tomorrow but the next day, and talk about it and see where we go from here, see what is best for our type of bowlers. And make sure that's what comes to our game against South Africa," said Simmons.

"We have to be better, there's no question about it. We've been terrible in the last 15 (overs), so we have to make sure we improve."

Ireland conceded 167 runs in the last 15 overs against West Indies, on a small ground against two well set batsmen in Nelson in game one, but it was more worrying that UAE could score 147 in the same period on the vast ground at the Gabba in Brisbane.

With South Africa - the world's No 2 - next, it is frightening what could happen if the bowlers do not get it right at the Manuka Oval. But, for the second game in a row, the batsmen rescued the bowlers and that delighted Simmons.

He added: "We showed great fight and we could afford to keep going, especially after Kevin (O'Brien) was out. It shows we have a lot of depth in our line-up."
