The Senators earned it — the game and the expected-goals battle both.

UTA 2 · OTT 4
◆ By the ModelJul 11, 3:20 PMxG: xgboost-0.758Edited for clarityDrafted from NHL play-by-play by Backcheck's model, worded for clarity by an AI editor that may not change a number. Nobody at Backcheck was at the rink. How this works

The Mammoth should have scored more. Their 3.63 expected goals matched Ottawa's 4.21 closely, but their 2-goal loss did not. The difference was Meriläinen, whose 0.935 save percentage stopped one goal above expected—a 29-of-31 night that equaled Utah's 1.63-goal underperformance.

Ottawa won through precision, not volume. Outshot 31-25, they generated 0.088 expected goals per attempt versus Utah's 0.063, translating that advantage into nine high-danger chances to six. All four Senators goals came on the rush, driven by relentless net-front positioning. Underneath the scoreboard's margin lay a narrow game: Ottawa simply converted better.

Michael Amadio's tip-in from the doorstep at 3:46 of the third period marked the turning point. By then, the Senators had seized control.

New to these numbers?

Two things happened in this game: who created the better chances, and who put the puck in the net. They are not the same thing, and this page separates them on purpose.

The one to watch is expected goals— the best single read on who deserved to win. When it disagrees with the scoreboard, that disagreement is usually the story. Nothing here is a projection; every figure is computed from this game's play-by-play. Full glossary →

xG
Expected goals. Every shot scored by how often that exact look goes in. 2.5 xG means the chances were worth about two and a half goals.
HD
High-danger chances — shots from the slot and the crease, where shots actually become goals.
Corsi
Every shot attempt, including the ones that missed or got blocked. A rough read on who had the puck.
Adj.
Score-adjusted. Teams that trail shoot more and teams that lead sit back, so this corrects the attempt count for the scoreboard.
GSAx
Goals saved above expected. A positive number means the goalie stopped more than an average goalie would have on those shots.
PDO
Shooting % plus save % — a luck gauge. It sits near 1.000 over a season, so a game far from it usually means the bounces decided it.

The read

Edited for clarity
◆ By the ModelJul 11, 3:18 PMEdited for clarityDrafted from NHL play-by-play by Backcheck's model, worded for clarity by an AI editor that may not change a number. Nobody at Backcheck was at the rink. How this works

The projection lines say 55% Senators win probability with a 2.4–2.7 goal spread. Translation: this is indistinguishable from a coin flip.

The underlying play tilts slightly toward Ottawa. The Senators generate 56.0% expected goals at 5v5 while allowing the Mammoth just 52.0%—a clean three-point advantage in shot quality. Both teams match at 53.0% Corsi, suggesting the performance gap is pure skill, not shot volume. Ottawa's PDO sits at 0.993, indicating discipline; Utah's 1.003 suggests they're running slightly lucky.

Where Ottawa gains traction is rest. The Senators arrive on one day off; Utah on three. That's margin-of-error territory in a single game, but combined with Ottawa's underlying advantage, it becomes worth tracking. Watch whether goaltender L. Ullmark starts or if the workload falls to the backup—a back-to-back can force such decisions.

The matchup hinges on Utah's elite individual offense and Ottawa's complementary defensive weaknesses. Dylan Guenther carries the Mammoth's score-sheet, posting 1.02 xG/60 with 28 goals and 15 assists—a conversion rate of 16.8%, which means he's finishing those chances. Daniil But runs 1.01 xG/60 and hovers at 5.6% conversion; his 2 goals and 2 assists suggest he's pressing, not producing at his underlying rate.

Brady Tkachuk anchors Ottawa's attack at 1.19 xG/60, already converting at 7.5% through 11 goals and 20 assists. Dylan Cozens operates at 1.00 xG/60, converting at 9.5%, which places him among the steadier finishers available. Both are working effectively within the Senators' system.

The weak points expose themselves in Utah's Maveric Lamoureux and Ottawa's Nick Jensen. If either becomes a pinch point—drawn out of position or exploited on coverage—the other team's personnel can punish it. In a game this tight, those micro-decisions define the scoreline.

The model knows what it's saying: this one depends less on team structure and more on which depth contributor shows up ready.
