Seattle Storm @ Connecticut Sun | 1:00pm ET | League Pass

This one carries weight that a second game of the season rarely earns. Connecticut opens its final year in Uncasville before the franchise relocates to Houston in 2027, and Sunday's home opener is the first chapter of a farewell tour the Sun's fanbase has been processing since the announcement. The crowd at Mohegan Sun Arena will be engaged in a way that goes beyond the standings.

The Sun enter 2026 as a rebuild in progress, but they signed Brittney Griner — a 10-time All-Star and former champion — to anchor the roster and provide the kind of veteran presence this team lacked last season. Hailey Van Lith showed real improvement in the preseason, averaging 12.5 points and 4.5 assists, and gives Connecticut a secondary creator alongside Griner's post presence. This isn't a playoff roster, but it's a group with enough individual talent to compete on a given night, especially at home.

Seattle is one of the most fascinating early-season teams to track precisely because expectations are low enough that every development reads as a bonus. The Storm shed Gabby Williams, Nneka Ogwumike, and Skylar Diggins-Smith in a deliberate roster reset built around youth. Awa Fam (No. 3 overall), Flau'jae Johnson (No. 8), and second-year forward Dominique Malonga — who tied in GM voting for most likely breakout player in the league — give Seattle a long, athletic core with real upside. They came into Sunday having beaten Connecticut in both of their last two meetings and opened the weekend by knocking off Golden State on Friday night.

Connecticut wins if Griner's debut generates the emotional lift that occasions like this tend to produce — a packed, emotionally invested arena, a franchise legend making her Sun debut — and Van Lith runs the offense efficiently enough to keep the Sun in front through three quarters.

Seattle wins if Malonga continues whatever she started on Friday, Johnson shows the scoring instinct that made her a lottery pick, and the Storm's athletic length gives Connecticut's frontcourt the kind of problems that veteran teams struggle with when they're still learning a new system.

Prediction: Seattle -1.5. The Storm won both recent meetings and have a developmental core that could be ahead of where most people expect this early. Connecticut's Sunset Season emotion is real but hard to sustain for 40 minutes. Storm win & cover.

New York Liberty @ Washington Mystics | 3:00pm ET | League Pass

New York got through Friday's opener against Connecticut without Sabrina Ionescu and the result wasn't close — the Liberty won 106-75, a statement even by the standards of a team this stacked. Sunday brings the road debut for a Liberty group that is still finding its identity under first-year head coach Chris DeMarco, now against a young Washington team playing its second game of the weekend.

The Liberty's depth is the point here. Breanna Stewart and Jonquel Jones are an elite frontcourt pairing. Satou Sabally — the marquee offseason addition — gives New York a versatile wing who can defend across multiple positions and contribute as a secondary creator. Betnijah Laney-Hamilton is back after missing all of 2025 with a knee injury, adding another layer to an already loaded rotation. When Ionescu returns, this group will look closer to what the preseason projections suggested. For now, Sunday is about maintaining chemistry and sharpening the habits DeMarco is trying to install.

Washington is building deliberately. Sonia Citron and Kiki Irafen were both rookie All-Stars in 2025 and enter their sophomore seasons as the cornerstones of what this franchise wants to become. Lauren Betts gives the Mystics a legitimate frontcourt presence going forward. The talent gap against New York is significant, but this is a team that will compete for 48 minutes regardless of the scoreboard — that's been the Mystics' calling card under Sydney Johnson.

Washington wins if the Mystics play free — nothing to lose, roster full of young players with reputations still being established — and their youth catches fire against a Liberty team that hasn't had enough games yet to be fully locked in defensively.

New York wins if Stewart and Jones impose the physical and positional dominance that their best lineups are capable of, and DeMarco's group uses the early-schedule games to build the specific habits they'll need when the competition gets harder in June.

Prediction: New York -9. The talent gap is real and the Liberty handled a road-caliber opponent in Friday's blowout even without their primary playmaker. Washington will keep it respectable, but New York's depth is too much for an early-season Mystics team still finding its footing. Liberty win, but Mystics cover.

Las Vegas Aces @ Los Angeles Sparks | 6:00pm ET | USA Network

The Aces lost to Phoenix on Saturday. The 16-game winning streak is over, and the defending champions head to Los Angeles for their first road game of the season needing a response. How a team like Las Vegas processes a loss — especially one on opening weekend, especially to the team it swept in last year's Finals — is its own kind of early-season information.

The Sparks are a legitimate test for a team in reset mode. Los Angeles had one of the more aggressive offseasons in the league. Nneka Ogwumike returns home after two seasons in Seattle, pairing her interior presence and veteran poise with a roster that already featured Kelsey Plum, Dearica Hamby, and Ariel Atkins, the latter arriving from Chicago. Plum and Hamby know this Aces organization from the inside — they played there — and Sunday's game is the first chance to put that familiarity to use against a Las Vegas group that will arrive motivated.

A'ja Wilson is not the kind of player who sulks through a bounce-back game. She averaged 23.4 points and 10.2 rebounds en route to her fourth MVP last season and elevated in every meaningful moment. Jackie Young, Chelsea Gray, and the rest of the championship core are experienced enough to treat Saturday as data rather than damage. The concern isn't effort — it's whether the rotational adjustments that a loss to Phoenix demands can be implemented on 24 hours' rest against a Sparks team that is also better than last year.

Las Vegas wins if Wilson and Young respond exactly the way champions respond — by making Saturday irrelevant by halftime — and the Aces' depth and defensive cohesion are enough to contain a Sparks roster that is still learning how its pieces fit under second-year coach Lynne Roberts.

Los Angeles wins if Ogwumike imposes herself in her Sparks homecoming — her size and positioning are legitimate problems for Las Vegas in the post — Plum finds a rhythm from the perimeter early, and the Sparks catch the Aces in the emotional hangover that occasionally follows a painful loss even for the league's best teams.

Prediction: Aces -5.5. Losing to Phoenix stings, but it doesn't change what this roster is. Championship teams in bounce-back spots tend to cover — the motivation is built in, and the Sparks, though improved, are not yet the kind of team that beats Las Vegas two nights in a row. Aces win & cover.

Phoenix Mercury @ Golden State Valkyries | 8:30pm ET | League Pass

Golden State is coming off a landmark inaugural season that ended with a playoff appearance — the first by an expansion team in WNBA history. Year 2 brings different expectations, and Williams is a significant reason why. The Valkyries' core returns largely intact and now has a genuine two-way wing to anchor the perimeter defense in ways that made opposing guards uncomfortable all season last year. This is a team that knows how to win already, and that foundation matters in early-season games when others are still sorting out rotations.

Phoenix is playing its second game in two days after Saturday's upset win in Las Vegas — a win that burned through real minutes from Alyssa Thomas, Kahleah Copper, and DeWanna Bonner. The Mercury made their case on Saturday that this roster is better than its preseason odds suggested, but sustaining that level on a back-to-back road trip against a team with Golden State's defensive personnel is a different challenge. Thomas averaged 15.4 points, 8.8 rebounds, and 9.2 assists last season and will need to be efficient even on limited legs.

Golden State wins if Williams makes her presence felt immediately at both ends, the Valkyries' defensive system forces enough Phoenix turnovers to build early separation, and the Chase Center crowd gives Golden State the home energy that made it such a difficult building to play in during Year 1.

Phoenix wins if Thomas manages her minutes well enough to stay effective late, the Mercury's back-to-back fatigue is less real than anticipated, and Saturday's confidence from knocking off the champions carries into a second road game in two nights.

Prediction: Golden State -4. The Valkyries at home, with Williams debuting against a Phoenix team running on fumes from Saturday's emotional win, is a strong position to be in. The Mercury are a better team than their preseason odds suggested, but back-to-back road games against two of the league's better teams is a steep ask. Valkyries win & cover.

The Aces-Sparks game tells us the most about championship-caliber resilience — how Las Vegas responds to adversity in Game 2 is the first real test of this team's 2026 character. But Williams-Valkyries is the game with the best individual storyline, and the Sun's Sunset Season opener carries emotional weight that no other game on the slate can match. Sunday closes a weekend that delivered an opening-night upset and more questions than expected.
