The Senators won 6-2, but expected goals suggested a tighter contest: xG split 3.68–3.24 in Ottawa's favor. The Bruins held 42% of shot attempts and tied the Senators at 6 high-danger chances. The 4-goal final margin significantly exceeded the underlying metrics.

The overperformance was stark. Ottawa outperformed its xG by 2.32 goals while Boston underperformed by 1.24. Goaltending explained the variance. J. Korpisalo posted a 0.706 save percentage and allowed 2.8 goals more than expected; L. Ullmark saved 1.2 above expected at 0.900. J. Swayman, Boston's starter, actually excelled — he saved 2.7 above expected and posted a 0.909 mark — but his strong outing was drowned out by his team's deficit.

F. Zetterlund's slap shot from the high slot in the second period marked the turning point. He recorded 2G and 1A in 17:12. D. Batherson posted 1G and 2A in 16:11, while D. Cozens contributed 1G and 2A in 15:40.

Ottawa's special teams converted efficiently. The power play scored 2 goals on 7 shots, well above the 0.32 expected goals mark. Both teams were lethal on the rush — Ottawa buried 3 goals on 24 chances, Boston 2 on 25 — but neither team converted rebound opportunities, with Boston creating four (zero goals) and Ottawa five (zero goals). Ottawa's proficiency at low-danger scoring combined with Korpisalo's weak evening in net transformed a close metrics matchup into a convincing victory.

Ottawa's 55% win probability rests on a simple fact: the Senators dominate underlying play. They generate 56.0% expected goals and control 53.0% of Corsi territory against a Boston team stuck at 47.0% xG and 49.0% Corsi. The projected 2.7–2.4 scoreline isn't a squeaker—it's the widening gap between what's actually happening and what the Bruins have banked on unsustainable finishing.

That unsustainability is Boston's problem. At 1.023 PDO, the Bruins are overperforming high-quality chances by nearly three percent. Regression is not a forecast; it's a timer. Ottawa sits at 0.993 PDO, suggesting the Senators have slightly underperformed their looks and have variance working in their favor.

The goaltending matchup adds uncertainty. L. Meriläinen faces a back-to-back, inviting either fatigue or a benching.

Brady Tkachuk is Ottawa's offensive engine at 1.19 xG per 60, though his 11 goals and 20 assists on 7.5% shooting point toward eventual regression. Dylan Cozens, operating at 1.00 xG/60 with 13 goals and an elite 9.5% shooting rate, is the sharper threat. Neutralize one, and Boston can compete.

Boston's counter is Viktor Arvidsson, whose 1.04 xG/60 and 13.0% shooting (18 goals, 24 assists) is a mirage waiting to collapse. Tanner Jeannot's 0.75 xG/60 reminds you he's a depth scorer, though his 8.3% clip keeps him functional.

The mismatch lives on defense. Elias Lindholm's weak-side exposure invites Tkachuk into dangerous ice. Ottawa hasn't sustained high hard-chance or rebound conversion, but Tkachuk's shot quality and volume suggest the team can lift those numbers against a vulnerable backend.

The model's lean is Ottawa across every layer: not explosive, but durable. Play to form, and the Senators win in regulation.
