Storm vs Mercury Game Preview
The Seattle Storm enter this matchup having made some significant changes in the offseason. They were the third wheel trade partner in the deal that sent Kelsey Plum to the LA Sparks and Jewell Loyd to the Las Vegas Aces. Seattle got some guards in that deal that they hope can team up with Nneka Ogwumike and Skylar Diggins to get back to the postseason. But the loss of Loyd will surely negatively impact their offense in the early stages of 2025.
On the other side, the Phoenix Mercury had a turbulent offseason of their own. Diana Taurasi retired after a long and illustrious career, while Brittney Griner joined the Atlanta Dream. But it wasn’t all bad for the Mercury, as they brought in a perennial league MVP contender in Alyssa Thomas along with the always dangerous Satou Sabally.
The frontcourt play of the Mercury will be key in this game, as Seattle’s duo of Ogwumike and Ezi Magbegor is one of the best in the W. How well Thomas, Sabally, and Kalani Brown work as a unit so early into their partnership in the Phoenix frontcourt will be huge on Saturday night.
Betting Insights
- Spread: Mercury -2.5
- Moneyline: Phoenix Mercury -145, Seattle Storm +105
- Over/Under: 162.5 points
The Mercury are favored going into this game at Sportzino, but there are question marks all over the court for both teams. If the Seattle guard group can produce at a high enough level to make the loss of Loyd not feel quite so painful, they could very well win this game outright on the road. Meanwhile, interior defense and three-point shooting will decide whether or not Phoenix can protect their home court to open their 2025 campaign.
Storm vs Mercury Prediction
Considering the Mercury’s recent success against the Storm and their home-court advantage, it’s reasonable to expect Phoenix to win a closely contested game. My recommendation is to take the Phoenix Mercury to cover the spread. Additionally, given the defensive strengths of both teams and recent trends, betting on the UNDER 162.5 points could be a solid choice.
