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

SJS 3 · BUF 6
◆ By the ModelJul 12, 6:32 AMxG: 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

High-danger chances were 6-6, yet the Sabres won 6-3 — the gap reflects their goaltending and execution in the crease. A. Lyon stopped 6 of 6 high-danger shots (100% SV%), while Y. Askarov faced a team that converted at 50% on those chances (3 of 6). The difference between elite and ordinary.

Beyond the danger zone, the Sabres controlled the broader play. They held 56% of shot attempts (26–20) and generated 60% of expected goals (4.47–2.94). But the real edge was quality: the Sabres created chances worth 0.081 xG per shot; the Sharks managed 0.056. That precision translated to a 3-goal margin.

J. Quinn was the engine. He scored 3 goals and added an assist in 15:09, including a wrist shot from a sharp angle at 17:14 of the third. R. Dahlin orchestrated with 3 assists in 20:07, and R. McLeod added 3 assists in 17:02.

The Sabres also dominated in transition: 5 goals on 25 rush chances versus the Sharks' 3 on 24. Marginal advantage there, but it compounded over 60 minutes.

Y. Askarov faced a heavier workload and cracked under pressure. He saved 20 of 25 shots (0.800 SV%) and was 0.53 goals worse than expected — a clear measure of his struggle. A. Lyon, meanwhile, was a wall: 17 of 20 (0.850 SV%), and his 100% mark on high-danger attempts decided the game. The Sabres outperformed their xG by 1.53 goals, a reflection of both sharp finishing and superior net-minding. When everything breaks right, 6-3 is what you get.

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 12, 6:52 AMEdited 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 model projects this as nearly a pick'em: the Sabres at 54% win probability, with expected goals between 2.4 and 2.7. The Sabres are riding genuine hot form, but the underlying analytics suggest tonight is legitimately close.

Buffalo is 8-1-1 in its last 10 games, a scorching pace. San Jose sits -8 in goal differential over that same stretch, suggesting structural problems. Yet season-long 5v5 numbers show Buffalo holds only a modest edge: 50.0% expected goals percentage to San Jose's 48.0%, and 49.0% Corsi to San Jose's 47.0%.

The catch is Buffalo's record-setting PDO. The Sabres are at 1.020, which means they're converting chances at an unsustainably hot rate. San Jose sits at 0.998, closer to true outcome. Expect Buffalo to regress; the question is how much and whether the Sharks are good enough to punish it.

Pavol Regenda anchors the San Jose attack at 1.10 expected goals per 60 minutes, with 5 goals and 1 assist, including 2 high-danger goals. He's shooting 16.1%. Igor Chernyshov, the Sharks' defensive weak link, generates 0.91 xG/60 with 6 goals and 8 assists (1 high-danger goal) while shooting 15.0%. Buffalo counters with Jason Zucker, who posts 1.07 xG/60 with 14 goals and 14 assists, including 6 high-danger goals, on 15.1% shooting. Josh Doan contributes 1.01 xG/60, 15 goals and 18 assists, with 2 high-danger goals and 11.5% shooting.

Both teams are remarkably similar in shot quality: San Jose and Buffalo each sit at exactly 0% high-danger and 0% rebound goal rates. The game may turn on which team can break this bottleneck, or simply who capitalizes on the chances that do materialize.

This is the kind of matchup where the model's slight lean to Buffalo reflects form and matchup, not superior talent. The Sabres are hot and deserve respect. The Sharks are deeper in the standings for reasons that show up in recent results, not underlying efficiency. Flip the coin and call it.
