How it happened

It did not start that way: the Wings led 26–19 after one quarter and by as many as 14. The fourth quarter was the swing — the Mercury won it 26–18 — and the Wings led 47–43 at halftime. The game had nine lead changes; the Mercury’s largest lead was 1.

The Mercury’s bench outscored the Wings’, 27–15. For the Wings, Paige Bueckers scored 30 (12-of-22) and Jessica Shepard 17 (5-of-15).

The Mercury made 28-67 from the field (42%) and 5-21 from three; the Wings 31-74 (42%). Turnovers ran 5–9, and points off turnovers 6–14 in the Wings’ favor — the margin came from shooting, not possession control. Rebounds went 32–42, points in the paint 40–22.

What it means

A reason to be cautious about carrying this game forward: Kahleah Copper’s previous-10 average (23) already sat 2.1 above her season mark, so against recent form the game is a smaller outlier than the season averages make it look; the Mercury gave up more points off turnovers than they scored, 14–6. One game is still one game.

After the result the Mercury were 16-27 and the Wings 26-17 (team schedules through September 21). The Mercury’s 87 was 2.6 above the 84.4 a game they averaged entering it.

This did not come against one of the league’s softest defenses: the Wings allow 85.3 points a game (standings as of Sep 29), 11th-most of 15.

Next up: GS at DAL on Sep 30, where the market consensus has the Valkyries favored over the Wings by 4.5 with a total of 155.5 (PropBetEdge capture, Sep 29, 11 books). Player props enter the board inside 36 hours of tip.
