With nine goals scored in their past two games – 10 in their last three – Martinez Losa said pre-match he hoped Scotland would retain the clinical edge shown against Israel but stressed it was "not something you can assume is going to happen all the time".
It was certainly non-existent in the first half in a then roasting and sun-laden Nitra.
The front three of Emslie, Martha Thomas and Kirsty Hanson all threatened, but nothing turned out to be too testing for Maria Korenciova in the home goal.
In contrast, on her first competitive start, goalkeeper Eartha Cumings had to push away a tricky lob attempt from Patricia Hmirova after Ludmila Matavkova dilly-dallied in getting her close-range shot away and allowed Sophie Howard in to block.
In uncomfortable conditions, the one player familiar to kicking a ball in 30-odd degree heat, Angel City's Emslie showed them how it is done. The LA-based winger slid in from the right to sneak the ball beyond Korenciova.
The heavens then opened with thunderous clouds covering a dark sky only brightened by the sharp flash of lightning every few seconds.
After a prolonged period back in the dressing room drying off, the players eventually resumed and, momentarily, it appeared some Scottish minds were still indoors.
Maria Mikolajova whipped a sumptuous ball to Hmirova at the back-post, where she somehow contrived to head the ball on to the woodwork instead of over the goalline.
It could have been an embarrassing moment for Scotland. Instead, the second goal was to leave the hosts blushing.
Matavkova inexplicably gave the ball away in the centre of the goal and, while Emslie may not have known much about it, the clearance bounced off the winger to seal victory.
