Porterfield's opening partner Paul Stirling will not only be keen to bounce back from his golden duck against the Windies at Clontarf but also get to that elusive half-century which he has failed to do for either Middlesex or Ireland this season despite promising starts.
He will probably be dropped from the team today, with James McCollum the obvious replacement at No.4 having scored 102 for the Wolves against Bangladesh last Sunday, and the Waringstown batsman is overdue his second one-day global after being summarily dropped after his first-ball duck in India in February, only because Ireland needed three specialist spinners.
Ambris, playing only his fourth ODI, and Hope, a century-maker in each of the team's previous two matches in the tournament, shared an opening stand of 84 to give the Windies a solid start to chase.
In reply, Ireland were bowled out for mere 185 in 34.4 overs. Paul Stirling and Balbirnie then went about rebuilding the innings. O'Brien, who had batted with great intent from the off, deposited Jason Holder for three sixes in a row in the 48th over. However, West Indies' firepower in batting meant they had enough in the tank to chase the target down on a flat pitch, even if the outfield was rendered sluggish due to rain on the previous day.
Ambris continued to fire though in a fluid style. Ambris brought up his maiden One-Day International hundred in 89 balls with a punched single to a joyous West Indies changing room.
Carter and Holder kept the West Indies on track for victory with a 75-run partnership before Holder was sent packing by Rankin for 36. It might have been different at the end if the massive appeal against Jonathan Carter first ball had been given. They both hit crucial boundaries at times when they needed and despite Holder sending one skyward and departing with one run to win, the West Indies chased down the required 328 with thirteen balls to spare. This is probably the best I've batted in global cricket.
On this day previous year, Ireland were preparing to host their first day of Test match cricket, only for rain to delay the historic occasion by 24 hours.
He added: "We just didn't show up against the West Indies and couldn't string many partnerships together with bat and ball".
"I'm very positive that we can bounce back against Ireland, and when we play Bangladesh the second time around, we'll put up a much better performance", Holder said. I got boundaries on the up.
Ambris and Shai Hope had gotten West Indies' reply off to the flawless start, and they were aided by Ireland's bowlers not being disciplined enough.
