Saad scored an even-strength goal and added a power-play assist in Tuesday's 5-2 win over the Capitals.
Both points came in the first period as the two clubs battled to a 2-2 tie, but the Blues dominated after that. Saad has a tidy two goals and six points over the last six games, and on the season the 29-year-old has piled up 19 goals and 36 points through 58 contests.
