Smejkal gave the Senators a 1-0 lead at 10:03 of the second period, scoring with a shot from the left circle that trickled five-hole on Ullmark.
“When I saw [Senators defenseman Erik Brannstrom] crossing the line, I knew he was going to find me there,” Smejkal said. “So, I was expecting that, and I found a little hole and it went in, so great feeling.”
Jakob Chychrun scored 51 seconds later to make it 2-0. He took a cross-ice pass from Drake Batherson on a 3-on-2 rush and scored short side from the left circle.
“We got to remember this going into next year, that you just get through these situations and you just play tight. Try to play as tight as possible, this is going to happen,” Forsberg said. “And just as a team, you have to deal with it. And today we ended up getting two points.”
Zacha cut it to 2-1 with a power-play goal at 12:44 of the third period, getting to a rebound in front and finishing with his backhand.
“We just had a little bit more volume of shooting,” Zacha said. “I think before we tried to pass it around the perimeter and didn’t [shoot] that many pucks, and this time [we] get a shot, tip net front, and I was lucky to get it there, so I think that’s something we have to focus on more.”
Artem Zub scored a short-handed empty-net goal from center ice at 18:12 for the 3-1 final.
The Bruins outshot the Senators 23-2 in the third period.
“To finish on a positive note after the year we had, it’s definitely nice,” Senators captain Brady Tkachuk said. “You definitely feel a little bit better about yourself going into the summer, but I mean, we’re not winning that game if it’s not for [Forsberg] and the big saves that he made in the third period.”
NOTES: Senators defenseman Thomas Chabot (upper body) left the game late in the first period after taking a hit from Bruins defenseman Andrew Peeke. There was no update. ... Zacha scored his 21st goal of the season, tying his career high he set last season.
