Senators run the Capitals off the ice on the underlying numbers

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

◆ By the ModelJul 11, 11:52 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 Senators ran the Capitals off the ice — not in the scoreline, but in everything that mattered. Ottawa won 4–3, but the underlying numbers told a much darker story for Washington: the Senators controlled 66% of 5v5 expected goals (4.50–2.36).

A one-goal game concealing a rout.

The Senators' dominance came from shot quality. They generated 0.067 expected goals per shot compared to Washington's 0.045. The high-danger chances tell the story: Ottawa created 5 to Washington's 2. That's not luck; that's control.

Goaltending proved split. L. Thompson made 28 saves on 32 shots (0.875 SV%); L. Meriläinen finished 26 saves on 29 (0.897 SV%). Neither goalie was the deciding factor. The gap was elsewhere.

Both teams struck twice off the rush, yet the Capitals' efficiency was sharper: 2 goals on 20 chances versus Ottawa's 2 on 30. Rebound chances went Washington 5, Ottawa 4, but each team scored once. Where Ottawa won the game was volume—five high-danger looks to Washington's two. That margin doesn't fit a one-goal decision, but that's what the underlying numbers say.

The turning point came early in the third: Fabian Zetterlund's snap shot from the slot at 17:38.

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, 10:39 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 model projects a 2.4–2.8 goal game favoring Ottawa at 57% win probability. This is a matchup where the underlying numbers align: the Senators own the territorial edge.

Washington has crumbled lately, sitting at -12 in goal differential over its last 10 games. But the model's confidence rests on what Ottawa dominates at 5v5: the Senators post 56.0% expected goals share against Washington's 50.0%—a clean, repeatable edge. Corsi tells the same story. Ottawa drives play at 53.0% against 49.0%, meaning you'll watch the Capitals defend most of this game.

The turnover lives in PDO. Washington runs at 1.018—significantly elevated—while Ottawa sits cool at 0.993. At this point in the season, PDO regresses. The Capitals' hot shooting and goaltending are not sustainable; the Senators' luck is overdue to reverse. The model is betting on Washington returning to earth.

One wrinkle: C. Lindgren faces a back-to-back, which may force a backup start or deploy an underrested starter. This introduces noise into an otherwise clean possession argument.

The player edge goes to Ottawa. Brady Tkachuk leads at 1.19 expected goals per 60 minutes, posting 11 goals on 7.5% shooting—suggesting more upside. Dylan Cozens, at 1.00 xG/60, has found goals at 9.5%, also leaving room to run. Washington counters with Alex Ovechkin (0.97 xG/60, 19 goals, 13.8% shooting) and Anthony Beauvillier (0.89 xG/60, 14 goals, 10.4%), both running at elite conversion rates that won't hold.
