The tempo of the first half quietened as the break approached with the action concluding with an off-target attempt by Patri Guijarro.
Stanway made way for Missy Bo Kearns at half-time, with the England U23 captain making her senior Lionesses debut in Barcelona.
Kearns was forced into defending early on in her England career with Salma Paralluelo and Alexia Putellas both having chances, but neither was able to put them on target.
The home side’s pressure finally told on the hour mark as Pina netted with a low strike only seconds after coming on as a substitute.
Pina saw another attempt saved, this time from a free-kick, before earning her second ten minutes after her first.
