The Capitals earned it — the game and the expected-goals battle both.
Washington's 6–1 victory masked a much tighter underlying battle. Expected goals favored the Capitals 4.60–3.07 (a 60–40 split), yet they won by five. Goaltending performance and execution gaps created the gulf.
The Capitals dominated tactically. They held 57% of shot attempts (32–24) and 60% of 5v5 expected goals. High-danger chances split 7–5 in their favor. On underlying metrics, this was a 4–3 or 5–2 game at most.
Execution is where the scoreline exploded. J. Binnington (11/15 saves, 0.733 SV%) conceded 1.8 goals above expected—unsustainable against this volume. St. Louis couldn't finish: 0 for 5 on high-danger chances, squandering their most dangerous looks.
Washington's complementary play amplified the damage. L. Thompson (23/24 saves, 0.958 SV%) stopped 2.07 more than expected and was impenetrable on high-danger shots (5-for-5). The Capitals were lethal off the rush (4 goals on 36 chances) and aggressive on rebounds (2 conversions on 4 created).
Tom Wilson's snap shot from the slot (third period, 09:00) was the dagger.
J. Chychrun orchestrated with 3 assists. J. Carlson (1G, 1A) and A. Beauvillier (2G) supplied the bulk of the finishing.
