Two teams on the fringes of the WNBA playoff picture meet tonight, when the Phoenix Mercury visit the Chicago Sky as 1.5-point underdogs on August 3.
Despite Chicago playing its best stretch of basketball this season, my Mercury vs. Sky predictions and WNBA picks have Phoenix as underdogs by betting lines only, as it has dominated this head-to-head.
Mercury vs Sky prediction
Mercury vs Sky best bet: Mercury +1.5 (-120)
The Chicago Sky just outlasted Vegas 84-83, and Chicago is showing sound defensive form lately, winning four of six while holding opponents to a league-best 27.2% from three over that stretch.
The Phoenix Mercury are hot too, winning three of four and allowing just 82 points per game. They could get an offensive lift if Kelsey Plum returns to a lineup that ranks 11th in scoring.
More importantly, the Mercury have dominated this matchup, winning eight of the last nine meetings, including four straight in Chicago by at least five points.
I’d back Phoenix up to -1.5.

Taylor leads her team in scoring and is currently on a run of 15+ points in eight of the Sky’s last nine games.Enjoying Covers content? Add us as a preferred source on your Google account

Mercury vs Sky player prop pick
Alyssa Thomas Over 8.5 assists (+100)
She might not have crossed her 8.5-assist line in two previous matchups with Chicago this season, but current WNBA assist leader Alyssa Thomas has been dishing plenty of late.
She has a season-best 15 against L.A., giving her double-digit dimes in three of her last six, missing the Over by a single assist another time.
