With the season winding down in two days, the playoffs are right around the corner. Seven teams have clinched a playoff spot, meaning the Seattle Storm and Los Angeles Sparks will battle it out for the eighth seed.

First up, the Washington Mystics (16-27, 6-15 away) will square off against Sabrina Ionescu and the New York Liberty (25-17, 16-5 home). Tabbed as large 14.5-point spread and -1400 moneyline favorites at home, the Liberty hold the fifth seed over the Golden State Valkyries. While the five seed is nearly a lock, New York will look to finish the season out strong with just two games remaining. Eliminated from playoff contention, the Mystics have lost nine straight games and are down 0-3 in the season series against New York. Sonia Citron and Kiki Iriafen will look to make last-minute Rookie of the Year pushes. However, the season is all but over for the Mystics.

Caitlin Clark Is Out For The Remainder Of The 2025 WNBA Season

Next, the Indiana Fever (23-20, 12-9 home) will host the Minnesota Lynx (33-9, 14-7 away) in Indianapolis. -145 moneyline favorites on the road, the Lynx have clinched the No.1 seed. MVP candidate Napheesa Collier and DiJonai Carrington will remain out for tonight's contest, while it was announced that Caitlin Clark will remain out for the season. Commissioner's Cup champions, the Fever, have managed to stay alive amid several injuries and hold a one-game lead over the Seattle Storm for the eighth seed.

MVP front-runner A'ja Wilson and the Las Vegas Aces (28-14, 16-5 home) will square off against the Chicago Sky (10-32, 4-17 away) in Sin City. Winners of 14 straight games, the Aces have surged to the third seed and are heavy 18.5-point favorites at home. Suspended for the first half of Saturday's matchup against the Aces for detrimental comments to the team, Angel Reese hasn't laced up since September 3. Eliminated from playoff contention, Chicago's season is nearly over, and Reese (back) is questionable to play tonight.

2025 MVP Battle: A'ja Wilson, Alyssa Thomas, and Napheesa Collier

In the Valley, MVP candidate Alyssa Thomas and the Phoenix Mercury (27-15, 15-6 home) will host Kelsey Plum and the Los Angeles Sparks (20-22, 11-10 away).  7.5-point spread favorites, the Mercury hold the fourth seed, and are most likely t0 face the New York Liberty in the first round of the 2025 WNBA playoffs. While Thomas continues her MVP campaign, this is a must win for the Sparks. 1.5 games back of the Seattle Storm for the final playoff spot and eighth seed, a victory is needed to make the postseason.

For the late night showdown, the Seattle Storm (22-21, 9-12 home) will host the Golden State Valkyries (23-19, 9-11 away) in the Emerald City. Similar to the Sparks, the Storm are the eighth seed, and tonight is a must win! 7.5-point spread favorites at home, the Storm face a Valkyries team who will have a slim lead over the Fever for the sixth seed. The first team to make the WNBA playoffs in its inaugural season, Valkyries head coach Natalie Nakase is a leading candidate for Coach of the Year.

As the season comes to a close in just a few days, teams and players have limited games to solidify their case for awards and playoff spots.

WNBA Best Bets For Tuesday, September 9

Player Prop Bet #1: Alyssa Thomas

Alyssa Thomas 2025 WNBA Stats

GP: 37 | PPG: 15.8 | FG: 53.3 % | FT: 69.5 % | 3PT: 0  % | REB: 8.9 | AST: 9.2 | STL: 1.6 | BLK: 0.5

• OVER 24.5 Points + Assists (-128 FanDuel)

My first best bet for today, I placed one unit on Phoenix Mercury star Alyssa Thomas to record over 24.5 points and assists against the Los Angeles Sparks.

A leading MVP candidate alongside Aces star A'ja Wilson, I'm all in on Thomas tonight. Likely to win the fourth seed and face the Liberty, every game is critical down the stretch.

Making history all season-long, Thomas is truly one-of-one. Nearly averaging a double-double on the season with 15.8 points and 9.2 assists, here's why I love this player prop bet for today.

Providing Thomas logs a full game, she's soared well over this prop against the Sparks. While Los Angeles boasts a potent offense, defense has been their downfall. Ranked tenth in defensive rating (108.3), they allow the second-most points per game (88 PPG). In addition, they allow the second-highest opponent field goal percentage (45.3 %) and 3-point percentage (36.2 %).

Interrupting passing lanes hasn't been their strong suit, allowing the second-most assists per game (22.4) to opponents. In fact,  the Sparks allow the second-highest points, and third-highest assists to forwards.

While the defense has improved ever so slightly, Atlanta Dream star Rhyne Howard recently exploded for 37 points against the Sparks. Two days prior, she erupted for 19 points against LA.

Will Alyssa Thomas Win The 2025 WNBA MVP Award?

In two games against the Sparks this season, Thomas averaged 15.5 points and 11 assists. Shooting 63.2 percent from the field in those games, she's been lights out.

Passing Caitlin Clark as the WNBA's all-time single-season assist leader (342), Thomas last faced the Sparks in August 26 in which she recorded a league-high seventh triple-double. In the Mercury's 92-84 victory over LA, Thomas erupted for 12 points, 16 rebounds, and 15 assists in 35 minutes for Nate Tibbetts.  On May 21, Thomas recorded 19 points and seven assists in 33 minutes of action.

While this game doesn't affect the standings much for the Mercury, they won't give the Sparks any easy looks. With the MVP campaign wide open, it helps the Mercury have a clean bill of health. That includes Satou Sabally and Kahleah Copper.

Last matchup against the Sparks, Thomas made history as the only player in WNBA history to record 15+ rebounds and 15+ assists. The Sparks allow the third-highest paint points per game (37.7 PPG), an area where Alyssa Thomas shoots 46.5 percent. Given she shoots over 66 percent from the restricted area, a place where the Sparks have had difficulty defending (65.3 %).

Final WNBA Player Prop Betting Prediction: Alyssa Thomas OVER 24.5 Points + Assists (-128 FanDuel)

A must-win game for the Sparks, I'm expecting a close matchup today. Last matchup, Thomas excelled in finding her teammates in the paint, back door cuts, and has the innate ability to recognize her teammates mismatches. Plus, she's been unstoppable in driving downhill. Even with Dearica Hamby and Azurà Stevens, the Sparks lack rim protection.

• I'm taking Alyssa Thomas to record over 24.5 points and assists today. While she's cleared this line just once in the last five games, she's soared over twice against LA this season. There's no player quite like Thomas, and I'm not fading her tonight.

Player Prop Bet #2: A'ja Wilson

A'ja Wilson 2025 WNBA Stats

GP: 38 | PPG: 23.8 | FG: 50.5 % | FT: 85.2 % | 3PT: 38.2  % | REB: 10.1 | AST: 3.0 | STL: 1.6 | BLK: 2.2

• OVER 34.5 Points + Rebounds (-135 DraftKings)

My second best bet for today, I placed one unit on Las Vegas Aces star A'ja Wilson to record over 34.5 points and rebounds against the Chicago Sky.

While Wilson remains the front-runner to win MVP, she has two games remaining to prove just that. Given the Aces are 18.5-point spread favorites, there's always a chance of a blowout. Especially, given Angel Reese is questionable to play for Chicago tonight.

Wilson's original points prop line is juiced at 25.5 points, so I veered away from that. Since returning from injury, she's passed Napheesa Collier as the WNBA's leading scorer (23.8 PPG). With that, she's had an exceptional back half of the 2025 WNBA season.

Averaging 31 points per game alone in September, Wilson is putting up 25.1 points per game in 20 post All-Star matchups. With rebounding stats soaring, so have her shooting percentages. Since the break, she's shooting 52.5 percent, and 8.0 percent increase. In September, Wilsons' 68.6 field goal percentage is up nearly 38 percent from August.

Why A'ja Wilson Is A Leading 2025 WNBA MVP Candidate

Scoring 30+ points in four of the last five games, Wilson is averaging 30 points per game over that span. That includes back-to-back 31-point performances against the Sky and Lynx. Scoring 34 points against the Dream and 36 against the Mystics, Wilson has shown the ability to compete at the highest level against any opponent.

Having faced Chicago just twice, Wilson and the Aces will meet them for the third time since August 25. In both matchups, Wilson logged 32 + minutes,  and soared well over this prop line last outing.

On September 7, A'ja Wilson recorded 31 points and 11 rebounds in the Aces 80-66 victory over the Sky. Without Angel Reese, not only was Wilson dominant on the boards, she went 12-20 and 2-2 from 3-point range.

Unless it's a blowout and heach coach Becky Hammon pulls her, I'm all in on A'ja Wilson. While the Sky have Kamilla Cardoso and Elizabeth Williams, they allow the second-most points to centers.

Final WNBA Player Prop Betting Prediction: A'ja Wilson OVER 34.5 Points + Rebounds (-135 DraftKings)

In August, we saw centers such as Jonquel Jones and Tina Charles record 25 and 23 points alone. The Sky have been dreadful defensively, ranking twelfth in defensive raking (109.3). Considered an elite team on the glass, the Sky are notably a different team on the boards in the absence of Reese.

• I'm taking A'ja Wilson to finish her MVP campaign out strong and to record over 34.5 points and rebounds today. Clearing this prop line in six of the last seven outings against the Sky, she's also soared over this in four of the last five games. I do believe most of this prop line can come from points scored alone. Plus, Wilson has far increased her 3-point shot as of late. 

Best Spread Bet: Los Angeles Sparks vs Phoenix Mercury

Sparks Record ATS: 18-24, 12-9 away
Mercury Record ATS: 21-21, 12-9 home

• Los Angeles Sparks +7.5 (-108 DraftKings)

My third best bet today, I placed one unit on the Los Angeles Sparks to cover the 7.5 underdog spread against the Phoenix Mercury for -108 odds on DraftKings.

Aforementioned, this is a must-win game for the Sparks who are on the fringe of playoff contention. Trailing the Storm for the eighth seed, I do believe 7.5 points is a lot for a team that's facing elimination.

With a 20-22 record, it's been a tumultuous season under first-year head coach Lynne Roberts. However, she Sparks have been dealt numerous injuries to Cam Brink. Rae Burrell, and so forth. There's an abundance of talent on the roster, including Dearica Hamby, Kelsey Plum, Brink, Rickea Jackson, and Azurà Stevens just to name a few.

Will The Los Angeles Sparks Make The WNBA Playoffs?

0-3 against the Mercury this season, this won't be an easy feat for Los Angeles. However, they are 12-9 ATS on the road, and covered within 7.5 points in two of their three matchups.

Not to mention, the Sparks dropped back-to-back heartbreakers to the Atlanta Dream. In fact, both were blow out losses by 10+ points.  Just 2-8 against the spread in the last 10 games, it's easy to see why the book's aren't favoring the Sparks to cover in this one.

Discussed earlier, defense has been an issue for LA all season long. Given Phoenix ranks top three in defensive rating, can the Sparks keep up with their pace? Can they cut back their high turnover percentage?

Final WNBA Betting Prediction: Los Angeles Sparks +7.5  (-108 DraftKings)

I'm not 100 percent sure if the Sparks can upset, but there's plenty to play for tonight. Over the last 10 games, the Mercury have slipped in the rankings. Falling to seventh in offensive rating (105.5) and net rating (4.6), the Mercury are not invincible. After winning six straight games, they were upset by the Connecticut Sun, 87-84 on Saturday night.

• I'm laying the points with the Los Angeles Sparks tonight. They've kept two of three games within five points or less. With the season on the line, expect the Sparks to come out extra motivated to win that last playoff spot. If the Sparks want to compete, they will need a complete team performance.
