Draftkings MLB Showdown Picks: Mariners vs. Blue Jays 10/19/25

Major League Baseball presents Draftkings baseball fans with an American League playoff matchup featuring the Seattle Mariners and the Toronto Blue Jays. Let’s take a look at this MLB game from a DFS perspective.

Before we dive into the Seattle Mariners vs. Toronto Blue Jays 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 tomorrow night’s Mariners vs. Blue Jays matchup.

Draftkings MLB Showdown Picks

On Sunday night, Major League Baseball presents the sixth game of a seven-game American League playoff series featuring the Seattle Mariners and the Toronto Blue Jays.

How are these two teams playing entering tomorrow evening’s MLB playoff game? The Toronto Blue Jays arrive at the sixth game of this seven-game series with the Seattle Mariners playing quality baseball. The Blue Jays have won four of the team’s last seven games played in the 2025 MLB season, including a dominant 13-4 win over the Seattle Mariners three days ago.

Similar to the Toronto Blue Jays, the Seattle Mariners arrive at the sixth game of this American League Championship series playing good baseball. More specifically, the Mariners have won five of the team’s last eight games played this season, including a 3-1 win over the Toronto Blue Jays last week.

Captain-Logan Gilbert, Starting Pitcher, Seattle Mariners $11,400

Now that we have identified how both of these teams are currently playing let’s shift our focus to this American League Championship series game. Starting pitcher Logan Gilbert has certainly been a standout performer for the Seattle Mariners this season. With that said, how has Gilbert performed from a statistical standpoint? Let’s review the veteran pitcher’s relevant game data from the 2025 MLB regular season to answer that question.

In 25 starts made in the 2025 MLB regular season, Seattle Mariners starting pitcher Logan Gilbert compiled a 6-6 (win-loss record), a 3.44 ERA (Earned Run Average) and a 1.03 WHIP (Walks and Hits per Inning Pitched) which ranks eighth in MLB. It should also be noted that Gilbert amassed 173 strikeouts while allowing only 31 walks in 131 innings pitched in 2025.

More recently, in the Seattle Mariners 8-4 win over the Detroit Tigers six days ago, Seattle pitcher Logan Gilbert pitched six quality innings while scattering four hits and no walks. Additionally, Gilbert struck out seven Detroit Tigers batters in the game.

In my opinion, Logan Gilbert is the most likely player to post the most Draftkings points in this MLB playoff game. For that specific reason, I am backing Seattle Mariners starting pitcher Logan Gilbert at the captain position for this one game MLB DFS slate.
