The African trio of Efih, Adubea and Kanteh were among the 11 new arrivals at the Huelva-based outfit this season, uniting with Hajri, who is set for her third term at Sporting.
Before Tacon's encounter, Hajri started alongside Efih in midfield, with Adubea upfront as Patri Ojeda's strike gave Sporting a 1-0 win over Sevilla.
On Saturday, Kanteh opened the scoring in the 22nd minute thanks to Yoko Tanaka's assist for Sporting, but the Spanish top-flight debutants secured the equaliser eight minutes later.
In the search for a win, Hajri was brought on for Ojeda in the 31st minute and she netted what turned out to be the winner for Sporting two minutes later at the Estadio Nuevo Colombino.
Having won their first silverware, the African ladies will take motivation to the new season as they open their 2019-20 campaign against Atletico Madrid on September 7.
