The Sharks extended their lead to 3-0 when Matt Benning hit Couture cutting between two defenders for a breakaway that Couture finished by sliding the puck in between Allen's legs at the 3:44 mark of the period. Marc-Edouard Vlasic also assisted on Couture's team-leading 13th goal of the season.
Hertl capped the scoring with an empty-net goal off assists from Labanc and Timo Meier with 2:14 remaining.
