Senators goaltender Craig Anderson made 37 saves; it was the second straight game he allowed one goal and made at least 36 saves.
Lajoie, a rookie defenseman, tied the game 1-1 with a wrist shot at 19:40 of the second period. He leads the Senators (3-2-1) with four goals. No defenseman in their history, regardless of status, has had more points (seven) in his first six games.
"I don't think I've went on a, I guess, heater like this in a while," said Lajoie, a fifth-round pick (No. 133) by the Senators at the 2016 NHL Draft. "Even in junior (Swift Current of the Western Hockey League), it was just kind of maybe every second game or something like that. But no, it's a pretty good feeling."
