Major League Baseball presents Draftkings baseball fans with an American League matchup featuring the Seattle Mariners and the Cleveland Guardians. Let’s take a look at this MLB game from a DFS perspective.
Before we dive into the Seattle Mariners vs. Cleveland Guardians game let’s review the rules for the Draftkings MLB 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 tonight’s Seattle Mariners vs. Cleveland Guardians matchup.
Draftkings MLB DFS Picks
Captain-George Kirby, Starting Pitcher, Seattle Mariners $12,200
On Friday night, Major League Baseball presents the opening game of a three-game American League series featuring the Seattle Mariners and the Cleveland Guardians.
How are these two teams playing entering this MLB game? The Seattle Mariners arrive at the first game of this three-game series with the Cleveland Guardians playing good baseball. The Mariners have won four of the team’s last six games played in the 2025 MLB regular season, including a 9-6 win over the San Diego Padres four days ago.
In direct contrast to the Seattle Mariners, the Cleveland Guardians are playing subpar baseball entering this MLB game. Let me be more specific. The Guardians have lost six of the team’s last eight games played in the 2025 MLB regular season, including a 10-0 shutout loss to the Texas Rangers last week.
Now that we have identified how both of these teams are currently playing let’s shift our focus to tonight’s contest. Starting pitcher George Kirby has certainly been a standout performer for the Seattle Mariners starting pitching rotation this season. Having stated that, how has the talented pitcher performed from a statistical perspective in 2025? Let’s review Kirby’s relevant game data from the 2025 MLB regular season to answer that question.
Through 17 starts made in 2025, Seattle Mariners starting pitcher George Kirby has compiled an 8-6 (win-loss record), a 4.05 ERA (Earned Run Average) and a 1.18 WHIP (Walks and Hits per Inning Pitched). Additionally, Kirby has amassed 97 strikeouts in 95.2 innings pitched this season.
More recently, in the Seattle Mariners 1-0 victory over the Baltimore Orioles earlier this month, George Kirby pitched exceptionally well. Kirby pitched seven quality innings while scattering three hits and no walks in the Mariners defeat of the Orioles.
What did we learn from the data just presented? Clearly, George Kirby can post a high number of DFS points on any given night. With that said, I fully expect that trend to continue in tonight’s matchup with the Cleveland Guardians.
In my opinion, George Kirby is the most likely player to post the most Draftkings points in this MLB game. With that said, I am backing Seattle Mariners starting pitcher George Kirby at the captain position for this one game MLB DFS slate.
Flex plays I like to play well in this MLB regular season contest (Draftkings price noted): Logan Allen, Starting Pitcher (Cleveland Guardians) $10,200: Julio Rodriguez, Outfielder (Seattle Mariners) $9,000.
