The Seattle Storm have won two of three head-to-head matchups with the Phoenix Mercury, but the visiting team will look to even up the season series tonight when the two teams clash at Climate Pledge Arena tonight.
My Mercury vs. Storm predictions target two combo props in what should be a low-scoring matchup.

Mercury vs Storm predictions
My Mercury vs Storm best bet: Alyssa Thomas Over 31.5 points+rebounds+assists (-125 at bet365)
The WNBA’s all-time leader in triple-doubles recently became the first player in history to record three in a row. I’m not calling for a triple-double against the Seattle Storm, but I’m betting on Alyssa Thomas to continue to rack up stats.
Thomas is averaging a healthy 16.1 points, 8.6 rebounds, and nine assists per game this season, good for 33.7 PRA. Over her last nine, she’s been even more productive, averaging 37.4 PRA while hitting the Over six times.
In two matchups with Seattle, Thomas has posted 34 and 33 PRA, and I expect her to reach that mark again tonight. With the playoff race heating up and Thomas’ Phoenix Mercury in the thick of the hunt for the No. 2 seed, she'll do all she can to secure a win.
Mercury vs Storm same-game parlay (SGP)
Alyssa Thomas Over 31.5 points+rebounds+assists
Gabby Williams Over 18.5 points+rebounds+assists
Under 164.5
Like Thomas, Gabby Williams has contributed in multiple categories this season. She’s averaging 12.4 points, 4.5 boards, and 4.4 dimes, good for 21.3 PRA. Williams went for 21/3/7 in her last matchup with the Mercury and will have another big outing here.
Over the last 10 head-to-head matchups, the Mercury and Storm have hit the Under seven times. Phoenix has gone 3-6-1 to the Under across its last 10, and Seattle has gone 5-5. The Mercury and Storm each rank in the Top 5 in defensive rating this season, and I expect a low-scoring matchup in Seattle tonight.
