Valkyries vs. Mercury Prediction, WNBA Betting Odds & Expert Picks: Aug. 22

Last Updated: August 22, 2025 11:22 AM EDT • 4 minute read X Social Google News Link

All signs point toward a hard-fought game in my Valkyries vs. Mercury prediction, with tipoff scheduled for 10 p.m. ET on Friday at PHX Arena in Phoenix (ION).
The Mercury are 6.5-point betting favorites at the best sports betting sites. Phoenix (21-14), which is playing on the second night of a back-to-back, could be without Kahleah Copper, who left the game last night. Golden State (18-17) hasn’t played since its 7-point loss to Phoenix on Tuesday, clinging to its No. 7 spot in the WNBA championship odds playoff picture.
For tonight’s WNBA prediction, I like the Valkyries to cover the spread, and Veronica Burton to play a pivotal role.

📈 Valkyries vs. Mercury betting odds analysis
The spread hasn’t moved since opening at 6.5 at the best sports betting apps, though it’s notable that the line has dropped after the Valkyries pushed on a 7-point spread in the same venue a few days ago.
Considering the Mercury are on the second night of a back-to-back and could be without Copper, I wouldn’t be surprised if this line closes at -6.

🛡️ Valkyries +6.5 (-105) ⭐⭐⭐⭐
The Valkyries aren’t the type of team you want to play on the second night of a back-to-back, potentially without one of your best players. They bring you into the mud with them, which will only be amplified by having a few days to sit with Tuesday’s result.
Golden State ranks fifth in the league in defensive rating and is comfortable in a low-scoring matchup with Phoenix. A defensive battle increases the chances of the Valkyries covering a spread of more than two possessions, as they are 21-13-1 ATS this year.
This line is painted 6.5 across the board, but Caesars’ -105 offering on the spread allows me to net a $9.52 profit on a $10 bet.

💰 Best Valkyries vs. Mercury player prop bet

⬆️ Veronica Burton Over 17.5 points + assists ⭐⭐⭐⭐
Burton might have locked up her Most Improved Player Award campaign against Phoenix on Tuesday. She finished with 24 points and 14 assists in 34 minutes during the 98-91 defeat.
Even if this game isn’t as much of a track meet, Burton should clear this mark. She’s done so in four of her past six outings, averaging 16.7 points and 7.2 assists per game over that span.
With this line being as high as -120 at the best sportsbooks, bet365 offers a slight bargain at -115. A $10 bet on my best Valkyries vs. Mercury player prop nets a profit of $8.70.

Who is the favorite to win Valkyries vs. Mercury?
The Mercury are 6.5-point favorites over the Valkyries on Friday at PHX Arena.
How do WNBA spread odds work?
When betting on the WNBA, the favorite needs to win by a certain number of points to cover the "point spread" - also known as the betting line. Conversely, the underdog needs to lose by fewer than the points displayed in the spread or win outright to cash. For example, a 3-point favorite would need to win by 4 or more points to reward bettors.
How do WNBA moneyline odds work?
When betting on the WNBA, the underdog will have the "longer" odds and is typically priced at "plus-money" odds that indicate the profit on a $100 bet. For example, a team with +150 odds would turn a $100 bet into a $150 profit - or a $10 bet into a $15 profit - according to our odds converter.
