Henderson goal against Birmingham was his first for Sunderland
Sunderland duo Jordan Henderson and Fraizer Campbell each scored to help their side to a comfortable third round Carling Cup win against Birmingham.
Henderson swept in a Kenwyne Jones cross to give Black Cats Steve Bruce the lead against his former club.
Campbell added to the lead when he beat keeper Maik Taylor to an Andy Reid cross and glanced it home.
Birmingham struggled to have an impact on the game as an attacking force as Sunderland eased into the last 16.
The visitors' boss Alex McLeish had made seven changes to the side which beat Hull in the Premier League last Saturday as he clearly showed his priority is top-flight survival rather than Carling Cup success.
Sunderland, on the other hand, fielded a strong looking side and Jones could have added to the lead given the home side by Henderson but saw his stabbed shot from close range blocked by keeper Taylor.
Campbell joined Henderson in scoring his first Sunderland goal and his effort provided evidence of the Stadium of Light outfit's superiority.
Taylor was again called upon when he plucked Lorik Cana's curling shot out of his top corner before John Mensah thought he had scored from close range only for his effort to be ruled out for a foul in the build up.
Birmingham striker Garry O'Connor had a shot blocked but it was as much as Birmingham could muster as they exited the competition.
