Brady Tkachuk scored 21 seconds into overtime, lifting Ottawa to a 3-2 victory over the Bruins and handing a win to Linus Ullmark in his return to Boston.

The Senators will probably see more of 25-year-old Mark Kastelic on the ice in tonight's game than they ever did in his Ottawa days.

It’s been a helluva walk down memory lane for Ottawa Senators goaltender Linus Ullmark the past few days. Earlier in the week, he was back in Buffalo, playing in his team’s 5-1 loss to the Sabres. Then he returned to Boston, starting the game between the pipes again as the Senators played the Bruins on Saturday.
