The new Swansea City man grabbed his first goal for the club less than 90 seconds after Cedric Van Der Gun had equalised for the Swans.
Sinclair's goal effectively took the Swans into round three and he was delighted not just to progress in the competition but to get his first goal for the club in only his third game.
Speaking to the club's official website, Sinclair said "It was a great feeling getting the goal
"The main priority was to get the win but I am happy to get my first goal and can start building on that."
