The Las Vegas Aces will once again play the Connecticut Sun, and the Washington Mystics will face the Indiana Fever on the road.

The late-night showdowns will feature the Toronto Tempo, who earned their first-ever victory this week, and the Los Angeles Sparks. The slate concludes with the Chicago Sky vs. Phoenix Mercury matchup in the Valley.

If you're betting on the WNBA today, the Fever, Aces, Mercury, and Sparks are favored to win on FanDuel. The Aces are fresh off a 29-point victory over the Sun and are 9-1 over the last 10 matchups against Connecticut. The Fever last defeated the Mystics 95-65 in September 2025 and are 5-5 against Washington over the last 10 outings.

A newly revamped Sky team will get the Mercury, which has won seven straight against Chicago since August 2024. Toronto will trek to Los Angeles for the first time, coming off its first-ever franchise victory over the Seattle Storm.

Here are my best bets, odds, and player prop predictions for the WNBA games on Friday, May 15. I've placed all of my bets within Fanatics and DraftKings Sportsbook.

WNBA Player Prop Picks For Friday, May 15

• Kelsey Mitchell OVER 2.5 Made Threes (-115 Fanatics)
• Caitlin Clark OVER 19.5 Points (-105 Fanatics)
• Nneka Ogwumike OVER 7.5 Rebounds (-116 FanDuel)
• Marina Mabrey OVER 2.5 Made Threes (-125 Fanatics)

Kelsey Mitchell OVER 2.5 Made Threes

I'm taking Kelsey Mitchell to record over 2.5 made threes as my first bet today. There are shooters, and then there are perennial 3-point shooters. Kelsey Mitchell is just that and more.

Mitchell picked up where she left off from last season and has been on an absolute tear. Through two games, she's averaging a career-best 26.5 points, along with 1.5 rebounds, 2.0 assists, while shooting 51.3% from the field and 27.8% from beyond the arc.

Mitchell is a three-level scorer. She can drive downhill, but most importantly, she is one of the best shot creators who can also catch-and-shoot from downtown. Her 3-point percentage may have dipped, but here's why I love this player prop bet for today.

While Clark continues to get comfortable after injury in 2025, Mitchell remains the Fever's primary scorer. In the season opener, Mitchell torched the Dallas Wings with 30 points in 33 minutes. During the 107-104 loss, she shot 11-of-22 from the field (50%), and 2-of-9 (22.2%) from three. In Indiana's 87-78 victory over the Sparks, Mitchell scored 23 points in 27 minutes, while shooting 9-of-17 (52.9%) and 3-of-9 (33.3%) from three.

It's not the percentage for me, it's the volume. In her first two games, Mitchell has 18 3-point attempts and is averaging 2.5 threes on 9.0 attempts per game. Overall, she ranks sixth in the WNBA with 18 3-point attempts and ranks second behind Marina Mabrey in attempts.

Along with her value, I like the matchup tonight. In 2026, the Mystics rank eighth, allowing 14 3-point attempts and 4.0 threes to guards. Mitchell shoots just 28 percent from above-the-break three, but the Mystics allow opponents to shoot 33% from the spot.

Perhaps her most efficient spot is the right corner three, where Mitchell is shooting 50%. The Mystics rank ninth, allowing opponents to shoot 40% from that range.

Mitchell is the type of guard who will score in transition, off fast breaks, or turnovers. While she's averaging 12 paint points per game, 6.5 of those are off turnovers.

Final WNBA Player Prop Betting Prediction: Kelsey Mitchell OVER 2.5 Made Threes (-115 Fanatics)

The Mystics are an intriguing team—they boast the second-best opponent 3-point percentage (26.95), but allow the fifth-most 3-pointers per game (26). The Mystics' backcourt looks vastly different as Georgia Amoore is at the helm, but also drafted two-way guard Rori Harmon.

In the season opener loss against the Liberty, Marine Johannés smoked the defense for 25 points on 6-of-13 3-point shooting. Against Toronto, Marina Mabrey shot 3-of-9 from three.

• I'm taking Kelsey Mitchell to score over 2.5 made threes today. The Fever play at the second-highest pace (86.8) and are averaging 95.5 points per game. While they shoot just 27% from three as a team, Indiana attempts 27 threes per game this season. Even if her percentage isn't there, the volume is, and so are the minutes (30.5). 

Caitlin Clark OVER 19.5 Points

For my second-best bet for today, I'm taking Fever star Caitlin Clark to score over 19.5 points against the Mystics.

Clark has admitted she's still recovering from mental hurdles following injuries that limited her to just 13 games in 2025. Clark is a perennial 3-point shooter, but she's shot just 3-of-16 from three this season. It has to get better, right?

Despite her shooting woes from deep, Clark is still averaging 22 points, 4.5 rebounds, 8.0 assists, and one steal in two games. In both outings, she's shooting 45.7% from the field and just 18.8% from three. I feel this line is too low, and here's why.

Clark is averaging 22 points in just 31 minutes, her lowest minute total since her rookie season. In the season opener, No. 22 scored 20 points against the Wings. Mind you, that was on 7-of-18 shooting from the field (38.9%), and 2-of-9 (22.2%) from three.

While her shooting woes continued, Clark tallied 24 points in 31 minutes against the Sparks. In a road game, on the west coast, she shot 9-of-17 from the floor, 1-of-7 from three, and 5-5 from the free-throw line. This season, Clark has been efficient in getting to the line—she's 9-9 (100%) from the charity stripe in 2026.

As mentioned before, the Mystics are a gritty team. They boast the third-best defensive rating (97) in the WNBA, but gave up 25 points to Marine Johannés. Clark has proven she's an elite facilitator, but can also score in bunches.

If Clark has scored 44 points through two games on abysmal 3-point shooting, why would I fade her today? As mentioned before, the Fever push the pace, and Clark called herself the best transition scorer in the league.

Final WNBA Player Prop Betting Prediction: Caitlin Clark OVER 19.5 Points (-105 Fanatics)

Don't overthink this. Clark has a 34.5% usage rate in 2026, the highest of her career. The Fever are an offensive-minded team, and the Mystics are allowing over 81 points per game. As Clark continues to get more comfortable, she's still the second-leading scorer on the Fever. Her 17.5 shot attempts are a career-high, and she is getting to the line at a good rate. Plus, she's shooting a career-best 45.7% from the field.

Clark is averaging 1.5 threes made per game, which is slightly lower than her 2.2 average in 2025 and 3.1 average in 2024. If she's been able to perform and soar over this line, despite such poor 3-point shooting, imagine when the shots start falling?

• I'm taking Caitlin Clark over 19.5 points today. Her shot volume and pace are enough to love this prop. Plus, I like the matchup, and the 3-point shots will start falling.

Nneka Ogwumike OVER 7.5 Rebounds

As my third-best bet, I placed one unit on Sparks star Nneka Ogwumike to record over 7.5 rebounds against the Tempo.

Ogwumike is back with the Sparks, the organization she spent the first 12 years of her career with. Her scoring production has dipped under head coach Lynne Roberts, but her rebounds have remained consistent. Through two games, she's averaging 14.5 points, 7.0 rebounds, 2.0 steals, and one assist.

Ogwumike and Dearica Hamby headline the Sparks' frontcourt, and Cameron Brink has worked her way into the rotation more since publicly being called out by Lynne Roberts. Even so, Ogwumike totaled 10 rebounds against A'ja Wilson and the Aces, and 5 against Aliyah Boston and the Fever.

The Sparks rank No. 8 in rebounding percentage (50%), which is middle-of-the-road. Where they've thrived is on the offensive boards (9.5), but they rank dead last in defensive rebounds per game (18.5).

I simply like this player prop given tonight's matchup. The Tempo is already without Temi Fábénlé and Isabelle Harrison. As a team, they allow the fourth-most rebounds per game (36), and average 35 boards per game this season.

The Sparks averaged a 27.5 offensive rebound rate, which is good for fifth in the league. Compare that to the Tempo, which ranks No. 11 at 23. Ogwumike has often been the cleanup in the interior and is averaging a career-high 9.1 offensive rebound percentage. That said, her 2.5 offensive boards per game is the most since the 2019 season.

Don't let the fact that Storm big Stefanie Dolson grabbed just three boards fool you: Seattle also has Dominique Malonga. We saw Shakira Austin tally 11 rebounds with the same exact prop line against Toronto on opening night.

Final WNBA Player Prop Betting Prediction: Nneka Ogwumike OVER 7.5 Rebounds (-116 Fanatics)

Despite the fact that Toronto deploys a smaller lineup, guards such as Brittney Sykes, Marina Mabrey, and Maria Conde have all made up for the boards. Regardless, Ogwumike can stretch the floor; she's shooting 67% from above-the-break three. In addition, she's shooting nearly 67% in the restricted area, where the Tempo allows opponents to shoot 64%.

• I'm taking Nneka Ogwumike over 7.5 rebounds tonight. Despite playing for the Storm last season, she cleared this line in over 40% of games last season. Dating back to 2025, she's cleared this line in four of the last five games. Tonight is a perfect opportunity for Nneka to dominate on the interior and take care of business on the offensive boards. Along with Kelsey Plum, Ogwumike averages the second-most minutes played on the Sparks (32.5). Overall, the Sparks have the size advantage.

Marina Mabrey OVER 2.5 Made Threes

For my last player prop bet, I placed one unit on Tempo star Marina Mabrey to record over 2.5 made threes.

It's safe to say Mabrey has earned every bit of that million-dollar payday. Her numbers were down in 2025 with the Connecticut Sun, but a fresh start appears to be what the star needed. In two games, Mabrey is averaging a career-high 26.5 points while shooting 45% from beyond the arc.

Similar players such as Kelsey Plum, Kelsey Mitchell, and Caitlin Clark are all heavy 3-point volume shooters. Not only is Mabrey tied with Mitchell for the most points scored in the WNBA (26.5), but she also leads the league in 3-point attempts per game (10) and 4.5 threes per game. All while shooting 45%. In reality, how can I fade this prop today?

I'm surprised this line hasn't moved since Mabrey exploded for six threes against Seattle and three against the Mystics. Scoring 53 points through two games, Mabrey is 9-of-20 from deep and has yet to log over 30 minutes of playing time for head coach Sandy Brondello.

We know the volume is there, and Mabrey boasts a 37.3 usage percentage, the highest of her career. In addition, she has a 44.4% 3-point rate, and 50.9% of her points originate from the 3-point line.

The last time Mabrey faced the Sparks, she tallied 19 points and 5 3-pointers in 2025. It's clear the Sparks' defensive woes have continued, even after trading for Ariel Atkins. LA ranks No. 14 in defensive rating (116.4), and allows opponents to make 8 3-pointers on 25 attempts. Against the Aces, Chelsea Gray shot 4-of-5 from three, and against the Fever, Kelsey Mitchell went 3-of-9 beyond the arc.

Thus far, Mabrey is shooting 40% from above-the-break, but is shooting 50% and 100% from the right and left corner 3-point spots. While the Sparks have defended the corners well, opponents are shooting 31% from above the break against LA.

• I'm taking Marina Mabrey to record over 2.5 made threes today. The Sparks are allowing the third-most points in the WNBA (96), and Mabrey has stepped up as a veteran for Toronto.
