Southampton FC Women's duo Laura Rafferty and Ciara Watling both featured as Northern Ireland beat Latvia 4-0 in World Cup Qualifying on Tuesday night.
After beating Luxembourg by the same scoreline on Friday night, the Green and White Army ensured of a winning return to Windsor Park after a nine year wait to play at their national stadium.
Saints defender Rafferty started the game as part of a back three, as Louise McDaniel's early second half goal kickstarted the goalscoring.
Captain Kirsty McGuinness, on her 50th cap for her country, added a second, before goals from Marissa Callaghan and a Rachel Furness penalty rounded off the scoring for a second successive 4-0 victory.
Watling came off the bench for Northern Ireland to replace Furness with four minutes to go, meaning both Saints players featured on a historic night at Windsor Park.
