The Blues added a third middle-from goal on a late man advantage in the second as David Perron found his 10th goal of the season. After a stretch of moving the puck around the zone, Brayden Schenn threaded a cross-ice feed from one dot to the other through the slot, where Perron put a wrister high, rising over the blocker of a diving Marc-Andre Fleury getting across to make it 3-0.
