The France international joined the Spanish side in a temporary switch last month and crossed superbly for Rafa Mir to head home a second goal on 75 minutes.
With Sevilla still in the hunt for their first league title since 1946, Julen Lopetegui's men sit just 3 points behind leaders Real Madrid, with 14 games left to play.
Having made his debut in red and white against Osasuna last weekend, the 26-year-old played 90 minutes on his inaugural home appearance, with Sevilla extending their unbeaten run in the league to nine games.
Keen to make an impact during his stay in southern Spain, Martial has European football to come too, with Lopetegui's side also still involved in the knockout stages of this season's Europa League.
