Mystics vs. Sun Preview

Any pick backing the Sun is risky, given their WNBA-worst 7-27 record this season, but if you doubt they can beat any team, they just did it on Tuesday against this same opponent.

It wasn't all that close either. Connecticut earned its seventh victory in 2025 with an 80-69 score. More importantly, this was a road win at CareFirst Arena in Washington, DC.

Tonight, the Sun will look for a repeat at home, hoping for another strong group effort as nine players showed up on the scoresheet in Tuesday's win.

Plus, the Mystics do not have a strong away record (6-11).

There is good value in this pick, and Bet Labs recommends it.

Mystics vs. Sun Prediction

The "Bad team coming off a win" system targets low-win-percentage WNBA teams (≤30%) coming off a win and now playing as an underdog (spread 2.5–18).

These teams often remain undervalued by the market, and bettors overreact to their last win, creating inflated lines and betting value.

Best Bet: Sun +2.5 (-110, Fanatics)
