L. Thompson stands tall as the Capitals edge the Senators

The verdict · coin flip

The Capitals won a genuine coin flip — neither side controlled the run of play.

◆ By the ModelJul 12, 8:11 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

Washington's 4-1 victory obscured an underlying tightness—expected goals finished 4.29-4.36, a 50-50 split. The actual separator: shot quality. The Capitals generated 0.077 expected goals per shot to Ottawa's 0.057, then actually converted those advantages into goals.

Ottawa had high-danger chances; they couldn't finish them. The Senators went 0 for 5 on chances that should convert regularly. They created six rebound opportunities and couldn't score on any of them. Against a different opponent, that wasted generation might not matter. Against Washington's finish, it was fatal.

The Capitals didn't always generate better chances—they simply weren't picky about which ones they finished. Washington scored two goals from low-danger spots, the kind that make opposing goalies cringe. They were lethal on the rush, finding two goals on 32 chances, the kind of efficiency Ottawa couldn't replicate elsewhere.

L. Thompson's line reads like a masterclass: 34 saves on 35 shots, a 0.971 save percentage that exceeded expectations by 3.36 goals. That gap is nearly the entire margin of victory. L. Ullmark, Ottawa's netminder, wasn't bad—he stopped 21 of 23 shots and saved 2.3 goals above expected. But Washington's goaltending surplus was simply larger.

The Senators' 3.36-goal underperformance on their own expected goals was never going to survive against Washington's execution. Sometimes close underlying play means close scorelines. This wasn't one of those nights.

    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, 7:46 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

    Ottawa's model edge is razor-thin. The Senators project to a 2.6–2.5 victory with a 53% win probability—essentially a pick'em by any statistical measure.

    The Senators are the hotter team by points pace, running 7–1–2 in their last 10. Their season 5v5 numbers back it: 56.0% expected goal share against Washington's 50.0%, paired with a 53.0% Corsi percentage that signals sustained territorial control. Ottawa drives play.

    Washington's weakness isn't talent; it's luck. The Capitals own a 1.018 PDO, running hot by the numbers and unlikely to maintain that rate. Once that regresses, Ottawa's underlying advantage amplifies. The Senators sit at 0.993 PDO, suggesting they're due positive variance.

    On the ice, Brady Tkachuk anchors Ottawa's edge. He's generating 1.19 expected goals per 60 minutes with 11 goals and 20 assists—two scored from high-danger areas. His 7.5% shooting rate leaves room for upward movement. Dylan Cozens complements the threat at 1.00 xG/60 with 13 goals and 15 assists, one arriving from high-danger play, and a 9.5% shooting efficiency that suggests he's operating in prime real estate.

    Washington counters with Alex Ovechkin at 0.97 xG/60, carrying 19 goals and 17 assists, and Anthony Beauvillier at 0.89 xG/60 with 14 goals and 9 assists. Both own two high-danger goals.

    The Capitals' structural vulnerability surfaces on defense: Declan Chisholm has been a liability. Ottawa will test that matchup. Nick Jensen represents Ottawa's defensive weakness.

    The numbers say Ottawa. The model says Ottawa by the narrowest margin. Recent form, PDO regression, and underlying play all tilt the same direction. But Washington can still win on the offensive talent of Ovechkin and Beauvillier. That's why it's a coin flip: the evidence favors one side, but the flip remains genuinely uncertain.
