L. Dostal stands tall as the Ducks edge the Mammoth

The verdict · coin flip

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

ANA 4 · UTA 1
◆ By the ModelJul 12, 8:05 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

Utah created more scoring chances but Anaheim executed better, the Ducks' 4–1 victory hinging entirely on conversion. The Mammoth generated eight high-danger chances to Anaheim's six, yet finished 0-for-8 in the danger area. The Ducks punished their opportunities: 4 goals on 6 chances (67%).

Possession favored Utah. The Mammoth commanded 56% of shot attempts (30–24 on goal), yet found themselves chasing a three-goal deficit. When underlying metrics closer to the outcome—expected goals split 4.65–4.39—suggest a nearly even game, execution becomes everything.

L. Dostal's goaltending was the execution that mattered most. The Ducks netminder stopped 29 of 30 shots, posting a 0.967 save percentage and saving 3.39 goals above expected. He turned a game the numbers called even into a comfortable Anaheim win. V. Vanecek, meanwhile, posted a 0.909 save percentage, stopping 20 of 22 shots.

Anaheim's shot quality explains the lopsided scoreline. At 0.093 expected goals per shot, the Ducks generated cleaner looks than the Mammoth's 0.059. Utah played the possession game; Anaheim played the efficiency game and won. The Ducks' rush game proved lethal—two goals on 19 rush chances—while Utah crashed the crease for four rebound opportunities without converting any.

The gap between volume and finish was Utah's undoing. Eight high-danger chances represents genuine opportunity. Zero goals on those chances represents capitulation. Anaheim, disciplined and sharp, delivered the punishment Utah couldn't inflict.

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, 8:03 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 2.6-2.7 goals per game with the Mammoth favored at 52% win probability—about as close to a pick'em as playoff projections get.

Both teams posted identical expected goals percentages (52.0% xG%) and nearly identical Corsi rates (52.0% for the Ducks, 53.0% for the Mammoth), which explains the tight forecast. Tactically, this should be an even matchup without a clear edge in possession or shot quality.

The Ducks' PDO sits at 0.981—running cold on the league's most volatile luck metric—and are due for positive regression. The Mammoth's 1.003 PDO suggests they're running closer to neutral. That shooting-luck gap could tilt the game toward the Ducks if variance normalizes.

The Mammoth arrive on three days' rest to the Ducks' one, the single largest structural advantage either team holds. In tight games, that rest edge compounds: fresher legs mean sharper defense and higher-quality opportunities late.

The Ducks' goaltending is the final wildcard: L. Dostal is on a back-to-back and may sit or start fatigued. The Mammoth's relative advantage in net—either way—could prove decisive in a game this close.
