Blues forward David Backes took a tripping penalty after failing to clear the Blues zone in the first period, veteran Steve Ott was whistled for interference in the second and defenseman Jay Bouwmeester was called for slashing Sharks center Joe Thornton out of frustration in the third.
"When you want to play a different way than the game's going to allow you to play, then you can go two ways," Blues coach Ken Hitchcock said. "You can either dig in and go the right way or you can become frustrated at times and try freelancing or in our case, take penalties. And we went the other way. We got frustrated, we took penalties and then regrouped ourselves in the third period, but we're down 2-0, the other team's able to sit on it a little bit."
The Sharks force teams to play a certain way. In the case of the Blues, the Sharks beat them at their own game with a heavy forecheck and by clogging up large portions of the ice. When the Blues couldn't move the puck, they got frustrated, and when they got frustrated, they sat in the penalty box.
"We reacted tonight," Blues defenseman Kevin Shattenkirk said. "We just weren't ourselves out there. That's something we just have to control a little bit more is our emotions. We have done it well the entire playoffs up until tonight. Again, that's an area we have to improve on and learn from tonight. It is going to be a bigger test when we go on the road to San Jose.
"They are a frustrating team to play against. They check you hard and are very disciplined. Their structure can frustrate you and I think that is what we do well, too. So, we have to make sure we are trying to get on the other side of that. They were smart tonight. They didn't react to us. They took our shots and were able to answer it."
