"We've had some good periods this year, but that second one might've been the best one we've had all year," Panthers coach Joel Quenneville said. "I thought we had good awareness, good playmaking, good patience with the puck, good speed. I thought we checked well. Obviously, scoring certainly helps, but I thought overall, we might've been doing everything you're looking to do in a period."

Evgenii Dadonov scored twice and had an assist for Florida (21-14-5), which is 6-2-0 in its past eight games.
"We started slow a little bit, but then we picked it up," said Panthers goalie Sergei Bobrovsky, who made 28 saves. "I thought we dominated the second period. And in the third period, we were solid defensively, good sticks, smart, got pucks out. It was a good game for us."
Tyler Ennis had a goal and an assist for Ottawa (16-20-5), who have lost three straight games. Craig Anderson made 25 saves.
"We didn't play our typical second period, which is fast, put pucks behind them, change on offense, get above them," Senators coach D.J. Smith said. "We took a couple of penalties and they ended up scoring. And then they just had us on long changes and, I don't want to say outworked, but outsmarted us."
