Brian Brobbey had netted a hat-trick in his previous Premier League outing, a 5-3 loss at Manchester City on 20 September.
However, Sunderland had failed to score in their two league matches while he was out with the hamstring injury he sustained while on international duty, and drew another blank against Leeds.
James Trafford dived low to his right to keep out Brobbey's deflected shot early on and then was alert to smother the ball at Brobbey's feet after the Dutch striker had put pressure on the visitors' backline.
While providing a focal point for Sunderland's attack, he got little change out of Leeds' three centre-backs and had touched the ball only 16 times before he was replaced in the 65th minute by Ukrainian Timur Tutierov.
