Fever vs Tempo parlay

Caitlin Clark 11+ assists

Aliyah Boston 10+ points/10+ rebounds

Tempo +10.5

Aliyah Boston is a handful when she’s not getting extra looks at the rim, averaging 17.4 points and 10.8 boards in her last five games. Projections call for a similar output tonight.

Meanwhile, Caitlin Clark has upped her playmaking during the Indiana Fever’s mid-season push, handing out 10 or more assists in five of her last seven games.

The Clark-Boston powered pick-and-roll attack will be especially potent against the Toronto Tempo’s undersized lineup, as Clark draws double teams and the 6-foot-5 Boston exploits smaller defenders on switches and weakside rotations. 

While my player prop picks are Fever-positive, I do see them in a tough situational spot tonight. The Fever are coming off a thrilling OT win in and have played three straight contests against top-tier rivals in Atlanta, Dallas, and New York.

The Tempo are back in Canada for the first time this month, with a packed house at Scotiabank Arena welcoming them home.

Toronto’s losing skid is rough, but it’s featured quality opponents, and the Tempo have covered in three of the last four showings.

Sparks vs Sun parlay

Sun moneyline

Under 169.5

Brittney Griner 6+ rebounds

While the Los Angeles Sparks have only recently struggled to score, the Connecticut Sun have been horrid on offense all season long.

Connecticut is averaging a league-worst 79.2 points per game, is last in offensive rating (98.6), and has the WNBA's lowest effective field goal percentage (46.9%).

There won't be much scoring tonight.

Still, the Sun beat Los Angeles when these teams met in May, and have some clear edges in this game. The Sun should control the paint, as the Sparks allow 42.3 ppg in the paint (third-most in the league), and Connecticut leads the WNBA in block rate (11.5%).

I'm rounding out my parlay by backing Brittney Griner to get 6+ rebounds. Griner is averaging 5.8 boards per game and has collected six or more in five of her last seven games, including both appearances in August.

With Griner likely to play tonight and Los Angeles' deficiencies on the glass, I love her rebounding prop as a value pick for any SGP.

Liberty vs Sky parlay

Liberty -3.5

Under 178.5

Breanna Stewart 20+ points

The Chicago Sky own a 106.2 offensive rating with Sydney Taylor and a 101.6 without her, and the team’s scoring dips from 88.7 to 82.9 when she’s out. The New York Liberty's interior defense is excellent, and I expect Chicago to struggle scoring with Taylor out or limited.

Breanna Stewart has averaged 13.8 points per game across her last four while shooting 35.7%. Over her first 31 games, she averaged 21.6 on 47.6% shooting. Chicago ranks 10th in defensive rating over its last five, and Stewart will break out of her slump with a big effort.

Dream vs Aces parlay

Aces -3.5

Angel Reese 15+ rebounds

Jackie Young 2+ threes

Angel Reese is coming off a 14-rebound effort in the loss to Indiana, and she’s gone eight straight games pulling down at least 10 rebounds. Reese has posted double-digit boards in six of seven career games against the Las Vegas Aces, tallying at least 13 in four of her last five.

This is a bit of a jump, but she's hit 15+ boards in three of six.

We must roll Jackie Young’s 3-pointers line into this SGP, because the Aces guard has crossed that mark in all nine games she's played since the All-Star break. That includes a 4-for-7 shooting night against the Atlanta Dream during a 109-87 romp on Aug. 3.

How to bet WNBA parlays today

Kalshi users can combine predictions for various markets for every WNBA game! Moneylines, spreads, and totals are fair game, as well as props for a player’s total points, assists, rebounds, 3-pointers made, and combo markets.

Prediction markets like Kalshi will set a projected total number for all the traditional markets and player stats, and users can predict whether the team will win/cover, if the total will go Over/Under, or whether players will reach certain statistical thresholds or not.

Combining predictions can increase a potential payday, but it also increases the risk level. If even one prediction in a three-leg combo is wrong, the whole thing is graded as a loss.

Kalshi is a federally regulated platform for trading event outcomes on prediction markets. Traders can buy and sell simple, transparent contracts that settle based on the outcome of real-world events. Markets revolve around a yes/no proposition, with prices adjusting dynamically based on traders’ perceived probability that the event will occur.
