Young stars in Ireland win
Craig Young took five wickets as Ireland eased to a comfortable victory over Scotland in the first one-day international in Dublin.
The 24-year-old medium-pacer helped limit the tourists at The Village in Malahide to 172 runs with figures of five for 46 on their way to being bowled out with nine overs remaining.
Ireland comfortably beat that total when Kevin O'Brien's unbeaten half-century saw them home with with plenty to spare as they finished on 173 for three to secure a seven-wicket win.
The Scots got off to a disappointing start as they lost Matty Cross for just nine runs after he edged Max Sorensen's delivery to wicketkeeper Stuart Poynter.
Young then made his introduction as he removed Calum MacLeod (25) and Hamish Gardiner (10) in quick succession.
The Derry bowler took his third when he clean bowled Preston Mommsen (10) to leave the Scots in trouble at 62 for four.
Michael Leask offered some resistance with a half-century but when he and Safyaan Sharif (18) also fell to Young, Scotland's hopes of posting a more challenging tally were over.
The Irish got off to a steady start in reply and took their time building their response.
They had scored just 11 runs when Iain Wardlaw removed John Anderson lbw, but the hosts soon stepped things up.
The 39-run partnership between Andrew Balbirnie (38) and Andrew Poynter (16) put them in control before the latter was caught by Cross with Ireland just shy of the 50-mark.
But that only marked O'Brien's arrival and his 56 not out was the catalyst for victory, with the Surrey batsman scoring two runs at the end to confirm the win with 13 overs remaining.
The teams meet again on Wednesday before Friday's final ODI.
