The 31-year-old left his first match in Boston after the trade to Ottawa as a winner.
Ullmark stopped a dangerous shot by Boston's Elias Lindholm 13 seconds into overtime, which allowed Ottawa's Brady Tkachuk to counter and shoot 3–2.
I'm not going to lie, it felt a lot, especially during the warm-up. I had goosebumps out there when I heard the crowd again, says Ullmark to reporters after the match, about the ovations he received from the Boston crowd.
Ullmark was praised several times during the emotional meeting, including when the giant screen showed a collection of highlights from his three successful seasons with Boston.
It's something you can look back on and say, yes, you've made enough of an impact in this community and this organization for them to show gratitude towards you as a player.
Ullmark's former goalie partner Jeremy Swayman was happy to see his old friend again. The two hugged during the warm-up.
It was a special match. We share a special bond, seeing him in another jersey felt different. I'm happy for him and his success, says Swayman afterwards.
It's fun to see him succeed.
