Tomas Hertl scored twice but the Sharks allowed three power-play goals and an even-strength goal to Claude Giroux after a bad giveaway in a 5-2 loss Saturday to the Ottawa Senators at Canadian Tire Centre.
The Sharks had to kill five penalties and allowed power-play goals to Brady Tkachuk, Tim Stützle, and Thomas Chabot as San Jose lost for the fifth time in six games.
It marked the first time this season that the Sharks had allowed multiple power-play goals in one game. San Jose entered Saturday with the NHL’s top-ranked penalty kill at 91.6%.
