There’s seemingly no limit to the goaltending depth in the Bruins’ organization.

Well, I wouldn’t go that far. But tonight in Ottawa Anton Khudobin let the Bruins know that they’d be in good hands in the short term if he’s called upon, and that maybe down the road he wants a legitimate chance to win an NHL job.

Khudobin made 44 saves on 45 shots, including 17 of 17, in the first period, in the Bruins’ 3-1 win against the Senators, who failed to wrap up the seventh seed in the Eastern Conference. Ottawa could still finish eighth with a regulation loss, a Washington win and a point by the Florida Panthers in the season finale for all three teams Saturday.

We already knew this wouldn’t be a playoff preview because the Bruins left Tim Thomas, Zdeno Chara and Patrice Bergeron home. But we had no idea the Bruins were going make Khudobin work extra hard for his day’s NHL pay.

With Tuukka Rask healing and working out, Khudobin’s services might not be needed. However, now the Bruins know that the 1.40 goals-against average Khudobin compiled in six NHL games prior to tonight might be somewhat reflective of his capabilities.

The Bruins conclude the regular season Saturday against Buffalo, which was eliminated from contention tonight.

▪Congratulations go out to rookie defenseman Torey Krug. The Boston free-agent signee recorded his first NHL assist, even if the scorekeeper stretched the rules a little bit. Krug started a play that finished with a Milan Lucic goal on the back end of a give-and go with David Krejci in the third period.

▪Lucic’s 26th goal pulled him within one of Brad Marchand and Tyler Seguin for the team lead. So Lucic still has a chance to lead the Bruins in goals for a second straight season.

Adam McQuaid didn’t take a shift after the early part of the second period. There was no useful update from the Bruins on the defenseman’s status.

Greg Zanon scored his first goal with the Bruins. The score was also his second point since joining Boston.

▪The Bruins have now won nine straight on Ottawa’s home ice.

▪With an assist, Brian Rolston now has at least one point in nine of his last 12 games. Benoit Pouliot has a goal in four of the last seven contests.
