An accomplished maiden limited-overs hundred from youngster Alex Hales set Nottinghamshire on their way to a comfortable victory over Ireland by 134 runs.

The 20-year-old hit a six and nine fours in an innings of 106 from 92 balls, sharing in a quick-fire second-wicket partnership of 150 with Ali Brown, who blasted 89 from 57 balls.

Will Jefferson also made a rapid 57, while Adam Voges contributed 48 to the Notts total of 346 for nine - a new county record in limited overs cricket.

Ireland never showed any sign of reaching their massive target and could only reach 212 for nine from their 50 overs, Andrew White top scoring with 51 while Samit Patel picked up three for 30.

With Chris Read absent attending the birth of his first child, Australian Voges took on the captaincy and chose to bat after winning the toss.

And although he saw Mark Wagh caught behind for just 11, Brown and Hales combined in blistering fashion as they smashed the Ireland attack all over Trent Bridge.

Brown hit John Mooney for three fours and a six off consecutive deliveries while Hales took 17 off a Peter Connell over soon after.

The 50 partnership came up off just 29 balls and Brown raced to his half-century off just 27 balls.

They brought up the hundred in the 12th over and added another 72 runs in the next 10 overs before Brown holed out to deep square leg trying to hit his third six.

England Lions all-rounder Samit Patel missed out on the fun when his leading edge off Kyle McCallan fell to midwicket but Voges kept the scoreboard ticking over while letting Hales off the leash.

Hales brought up his hundred with a punch through the covers but was then stumped attempting to launch Regan West for six.

At that stage Notts were 243 for four with 14 overs remaining, and Jefferson kept the momentum going with some well-timed strokes.

A flurry of late wickets slowed the run-rate down somewhat but Notts were still able to pass their previous best one-day total of 344 for six, set against Northumberland in 1994 in the old NatWest Trophy.

Ireland's batsmen struggled to produce the weight of shot needed to have any chance of pulling off a major upset and realistically were never in the hunt after falling to 39 for three in the 14th over.

Jeremy Bray steadied the ship with 41 before becoming the first of three victims of Patel's left-arm spin.

Kevin O'Brien (23) and Andrew Poynter (29) also fell to Patel, but Andrew White did manage to reach 50 off 57 balls in the final over.
