What happened: The Phoenix Mercury opened a lead over the Seattle Storm, taking a 31-20 edge after the first quarter at home. Phoenix set an early tempo while Seattle struggled to keep pace on the scoreboard.

Why it matters: The matchup carries added weight given the season series, with Phoenix having taken both prior meetings. A fast start reinforces the Mercury's edge as both teams jockey for position in a crowded Western Conference standings picture.

What to watch: Watch whether Seattle can tighten its defense and trim the deficit in the second quarter, and whether Phoenix's early shooting holds up.
