Draftkings WNBA DFS Picks: Mercury vs. Aces 8/21/25
Phoenix Mercury vs. Las Vegas Aces
August 21, 2025 10:00 pm EDT
The WNBA presents Draftkings basketball fans with a regular season matchup featuring the Phoenix Mercury and the Las Vegas Aces. Let’s take a look at this game from a DFS perspective.
Before we dive into the Phoenix Mercury vs. Las Vegas Aces game let’s review the rules for the Draftkings single game showdown contest.
Draftkings Single Game Showdown Contest Rules
You have $50,000 to utilize on five players from either team. However, one of those players will be designated as your team captain. The captain accumulates 1.5 times the standard fantasy points. Additionally, the captain is 1.5 times the standard cost of the flex position.
The remaining four players in your lineup will receive the standard fantasy points. Having stated that, it is highly important for you to identify the correct player for your captain position if you hope to win a large field DFS GPP (guaranteed prize pool) showdown contest.
If you have additional questions regarding the rules for the single game showdown contest, I recommend that you check out the Draftkings website for more details.
*I recommend that all readers review the starting lineups for both teams prior to setting your DFS lineup for this one game slate.
Here are my Draftkings picks for this tomorrow night’s Mercury vs. Aces matchup.
Draftkings WNBA DFS Picks
Captain-Alyssa Thomas, Forward, Phoenix Mercury $12,800
Talented forward Alyssa Thomas has been the leader in the paint that the Phoenix Mercury have needed to win games this season. With that said, how has the talented forward performed from a statistical perspective? Let’s review Thomas’s relevant player data from the 2025 WNBA regular season to answer that question.
In the 29 games that forward Alyssa Thomas has played for the Phoenix Mercury in the 2025 WNBA regular season, Thomas is averaging a rather impressive 16.1 points, 8.6 rebounds, 9.1 assists, 1.6 steals and 0.5 blocks a game.
Looking at the data just presented more closely, in the 29 games that Alyssa Thomas has played for the Mercury in 2025, Thomas has compiled a 54.3% field goal percentage and a 71% free throw percentage.
Earlier this month, in the Phoenix Mercury’s thrilling 85-82 victory over the Seattle Storm, Phoenix forward Alyssa Thomas certainly played at a high-level. Let me be more specific. In the Mercury’s defeat of the Storm, Thomas compiled 19 points, ten rebounds, 11 assists and three steals.
As I noted in the rules section above, selecting the correct player at the captain position for a Draftkings WNBA showdown lineup is absolutely vital if you hope to win a large field GPP (guaranteed prize pool) DFS contest. Keep that in mind as you construct your lineups.
In my opinion, Alyssa Thomas is the most likely player to amass the most Draftkings points in this WNBA game. For that specific reason, I am backing Phoenix Mercury forward Alyssa Thomas at the captain position for this WNBA regular season game.
Flex Plays
Satou Sabally, Forward, Phoenix Mercury $9,000
In addition to Alyssa Thomas, forward Satou Sabally has been a key contributor for the Phoenix Mercury in 2025.
In the 29 games that Phoenix forward Satou Sabally has played for the Phoenix Mercury in the 2025 WNBA regular season, Sabally is averaging a robust 17.1 points, 6.6 rebounds, 2.5 assists, 1.3 steals and 0.4 blocks a game.
In conclusion, I fully expect Satou Sabally to continue her outstanding play in tomorrow’s matchup with the Aces.
