Lettieri scored a pair of goals in AHL Toronto's 3-2 overtime win over Syracuse on Friday.
Lettieri has five goals and six helpers over six AHL outings. The veteran forward had one goal over nine NHL contests during his recent stint with the Maple Leafs. He's an option for future call-ups, but playing in one more NHL game would require him to pass through waivers for another reassignment to the Marlies.
