Borussia Dortmund had 69 percent of the possession in Lisbon, outshot Benfica 14-5, and Pierre-Emerick Aubameyang shot a 58th-minute penalty kick straight to Ederson as Kostas Mitroglou’s close-range strike after a goal area scramble held up.
Pulisic replaced Marco Reus in the 82nd minute and two minutes later hit a volley from the edge of the penalty area that Ederson batted away after a deflection. Pulisic also won a free kick, a corner kick, hit another volley over the crossbar, and sent in promising cross. The 18-year-old American also received a yellow card for an 84th-minute foul.
Borussia Dortmund hosts the return leg March 8.
