Phoenix Mercury vs Portland Fire Final Score & Over/Under Result — Sep 17, 2026

The market opened at 171.5, a figure that looked conservative from the first possession. Phoenix and Portland combined for 46 points in the opening quarter, already signaling that scoring pace would outrun the pregame number. The trend continued into the second quarter with another 47 combined points, pushing the halftime total to 93—well ahead of the 85.75 pace needed to clear the opener. That early over signal proved durable. The third quarter dipped to 44 combined, but the fourth erupted for 48, the game's highest-scoring period, sending the final combined total to 185, an over by 13.5 points despite the line creeping up just one point to 172.5 at tip-off.

Shay Ciezki led Phoenix with 22 points while Alyssa Thomas added 18 points, 8 rebounds, and 6 assists in the Mercury's 94-91 victory. Emily Engstler led Portland with 21 points and 7 rebounds, supported by Holly Winterburn's 18 points. Both teams entered with modest recent scoring profiles—Portland averaging 87.7 per game over their last ten, Phoenix 86.1—yet neither defense could contain the pace once the game began. The prior head-to-head meetings this season had ranged from 150 to 173 combined; this one landed squarely in that range but climbed well past the original market projection. DAGGER's pregame over call cashed decisively.
