The young striker, who represented Great Britain at the London 2012 Olympic Games, was at the double to seal the Trotters' progression to the fourth round of the FA Cup.Bolton shocked Premier League side Sunderland 2-0 on Tuesday night to advance to the fourth round of the FA Cup in a game that also marked American Stuart Holden's return to action after 15 months on the sidelines.
In a game desperately lacking in quality and clear-cut chances, the Trotters opened the scoring in the second half from Marvin Sordell's penalty, and the forward bundled home soon after to seal the tie at the Stadium of Light.
The Black Cats dominated the opening stages, with Craig Gardner's 20-yard effort curling over before Adam Johnson darted into the box and drew a smart save from Andy Lonergan in the Trotters' goal. Johnson was growing into the match and had the Trotters tied up in knots on the half-hour as he twisted and turned his way into the box, but his cut-back for Connor Wickham was smartly clipped away by Jay Spearing.
Bolton's first real chance came through Chris Eagles' effort that curled wide from the edge of the box soon after, but this stirred a late rally from the Black Cats.
Johnson's 30-yard free kick was neatly tipped behind by Lonergan, and, after the Trotters failed to clear the resulting corner, Stephane Sessegnon cut the ball to Titus Bramble, but the defender could only scuff wide with his left foot.
The second half began in a turgid fashion, but the deadlock was finally broken by Bolton just after the hour, in controversial circumstances.
Darren Pratley burst into the penalty area, before Jack Colback slid in to put the ball behind for a corner, although Kevin Friend adjudged the challenge a foul and gave a penalty that Sordell drilled down the middle of goal.
The game was over as a contest just eight minutes later as Eagles and Tyrone Mears combined on the right, before the fullbacks cross resulted in a scruffy melee in the six-yard box, that saw the ball fall to Sordell who prodded home his second.
Holden stepped onto the field as a substitute in the 74th minute to cement his return from a long-term knee injury that kept him out of action since the fall of 2011.
