Scotland defeated Costa Rica 4-0 at Hampden Park, aided by a brace from 17-year-old Emma Watson in only her second appearance.
Watson volleyed Scotland ahead after only five minutes, turning in a Caroline Weir free-kick.
Claire Emslie met a Weir corner to help double the lead via a Katherine Alvarado own goal.
It was 3-0 before the break as Emslie delivered for Weir to turn past keeper Daniela Solera.
Weir hit the far post, Sophie Howard’s diving header cleared off the line, before Watson struck again midway through the second half.
