Lorna Jack's half century ensured Scotland got the four-match series off to a winning start as they beat Ireland by 57 runs in the opening game at Clydesdale.

Jack hit five fours in her unbeaten 56 as the hosts posted 138 for 6 in their 20 overs.

Rush bowler Ellie McGee took 2 for 25, while there was a wicket apiece for Niamh MacNulty and Alice Tector.

The Irish reply was dealt a severe blow with the dismissal of skipper Amy Hunter in the first over.

They never really threatened thereafter, with only Alice Tector (20) making an impression.

The teams are back in action on Tuesday when they face each other in a 50-overs game at the same venue.
