This Senators vs. Bruins prediction starts with a market that has quietly changed its mind. The moneyline opened as a pick’em and now leans slightly toward Ottawa, while the total has climbed from 5.5 to 6. Boston enters Monday’s game at TD Garden at 2-1-0 after splitting a two-game road trip. Ottawa is 1-0-0 after a 3-2 win in Toronto, but it lost its top defenseman early in that game. Below, we work through the goaltending, the injuries and the price before landing on two picks.

Ottawa Senators vs. Boston Bruins Betting Preview
The goaltending matchup is the first thing to settle, and it is not settled yet. Linus Ullmark is the projected starter for Ottawa after he made 27 saves on 29 shots in the 3-2 win at Toronto on Saturday. That one start produced a .931 save percentage. However, his 2025-26 season was rougher, with a .891 save percentage and a 2.73 goals-against average over 49 games.
Boston’s crease is less clear. Jeremy Swayman opened with a 24-save shutout of the Rangers, then won 4-3 in overtime at Winnipeg. He has allowed three goals on 57 shots. Michael DiPietro started the back half of that back-to-back and made 26 saves on 29 shots in a 4-1 loss at Minnesota. One preview expects Swayman back in net Monday, while another projection lists DiPietro. Neither starter is confirmed, so every read below is provisional.
The schedule spot is close to even. Boston played Friday and Saturday on the road, then had Sunday off before returning home. Ottawa also rested Sunday after opening in Toronto. Still, the Senators play again Tuesday in Detroit, so this is the front end of their first back-to-back.
Injuries cut deeper on the Ottawa side. Jake Sanderson, who posted 54 points in 67 games last season, left Saturday’s opener in the first period with a lower-body injury. He is listed day-to-day, and one report has him missing Monday. Artem Zub (knee) and Andre Burakovsky (upper body) also sat out the opener. Boston, meanwhile, is still without Charlie McAvoy, who is serving a six-game suspension. Matthew Poitras is also out with a lower-body injury.
Up front, JJ Peterka scored in each of his first two games since arriving in Boston. Mark Kastelic leads the Bruins with three points, and new captain David Pastrnak has two assists. Ottawa got goals from new captain Thomas Chabot, Michael Amadio and Stephen Halliday in its opener. The Senators are also playing their first season without Brady Tkachuk, who was traded to Florida in June. Our Senators vs. Maple Leafs preview covered that opener in more detail.
The head-to-head history tilts toward Ottawa. The Senators won three of four meetings last season and outscored Boston 20-10. The last meeting was a 6-2 Ottawa win at TD Garden on December 21, 2025.

Senators vs. Bruins Prediction — Who Holds Ottawa’s Blue Line After Sanderson’s Exit?
Special teams are where this game could open up. Both clubs finished last season with penalty kills below 78 percent, Boston at 77.0 percent and Ottawa at 75.7 percent. Boston’s kill has started worse, allowing three goals on seven chances through three games. Minnesota cashed both of its second-period power plays in Saturday’s loss, and coach Marco Sturm called special teams the difference afterward. Meanwhile, both power plays converted near 24 percent a year ago. That combination gives each team a realistic path to a power-play goal.
Ottawa’s defensive depth adds to the case. Without Zub, and possibly without Sanderson, younger defensemen like Carter Yakemchuk and Tyler Kleven face heavier minutes against Boston’s top six. Ullmark’s .891 save percentage last season also sits below the level that usually anchors an under. In addition, the four meetings last season produced 30 goals, and three of them reached eight.
The market has moved the same way, lifting this total a half goal from its 5.5 opener. Hockey’s late-game math helps too. A trailing team pulls its goaltender, so one-goal games often finish with an empty-net goal. A game tied after 60 minutes also adds a goal for totals purposes, since overtime or a shootout settles it. The risk is Swayman. If he starts and stays near his early .947 save percentage, Boston can slow this game down. Boston’s power play is also 0-for-6, and exactly six goals would push. At -103, the over needs to cash about 50.7% of the time to break even. The value sat at the opening number, so this rates as a lean rather than a strong play.
The Pick: Over 6.0 (-103)
Senators vs. Bruins Prediction — Does Last Season’s 20-10 Goal Gap Still Matter?
Last season’s underlying numbers favored Ottawa. The Senators averaged 28.9 shots per game while allowing 24.4, a margin of about four and a half shots a night. That process edge showed up head-to-head as well. Ottawa won three of the four meetings, and only Boston’s 3-2 overtime win was decided by fewer than two goals.
The market is leaning the same way. The moneyline opened at -110 on both sides and has shortened to -115 on Ottawa. On the puck line, 73% of tickets sit on Boston, yet Ottawa has replaced Boston as the -1.5 side since the open. A price moving against the ticket count is the reverse line movement pattern, though this move is modest. The case against is real. Ottawa is thin on defense, Swayman has been sharp, and a near pick’em price leaves little cushion. Our Bruins vs. Jets preview covered Boston’s early form. At -115, Ottawa needs to win about 53.5% of the time to break even. That is a fair ask for the better process team, but not a generous one. If Swayman starts, this stays a thin lean.
The Pick: Senators Moneyline (-115)
Our Final Word on Senators vs. Bruins
Both picks rest on the same open question in Boston’s crease. A Swayman start tightens both reads, while a DiPietro start strengthens both. Ottawa’s missing defensemen cut both ways as well, adding to the over case while counting against the Senators’ side. Confirm the starters before puck drop.
The Over 6.0 (-103) leads, built on two penalty kills that finished last season below 78 percent. The Senators Moneyline (-115) follows, backed by Ottawa’s shot edge and a puck line that flipped against the ticket count.
