Major League Baseball presents Draftkings baseball fans with a National League matchup featuring the San Francisco Giants and the Arizona Diamondbacks. Let’s take a look at this MLB game from a DFS perspective.
Before we dive into the San Francisco Giants vs. Arizona Diamondbacks 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 Giants vs. Diamondbacks matchup.
Draftkings MLB DFS Picks
Captain-Logan Webb, Starting Pitcher, San Francisco Giants $12,000
On Monday night, Major League Baseball presents the opening game of a four-game National League series featuring the San Francisco Giants and the Arizona Diamondbacks.
How are these two teams playing entering today’s game? The San Francisco Giants arrive at the first game of this four-game series with the Arizona Diamondbacks playing below average baseball. The Giants have lost five of the team’s last six games played in the 2025 MLB regular season, including a 1-0 shutout loss to the Chicago White Sox two days ago.
Similar to the San Francisco Giants, the Arizona Diamondbacks are playing subpar baseball entering the opening game of this MLB series. More specifically, the Diamondbacks have lost four of the team’s last five games played in the 2025 MLB regular season, including a 7-3 loss to the Chicago White Sox last week.
Now that we have determined how both of these teams are currently playing let’s turn our attention to this evening’s contest. Starting pitcher Logan Webb has certainly been a solid performer for the San Francisco Giants this season. With that said, how has Webb performed from a statistical standpoint in 2025? Let’s examine the veteran hurler’s relevant game data from the 2025 MLB regular season to answer that question.
In 17 starts made this season, San Francisco Giants starting pitcher Logan Webb has compiled a 7-5 (win-loss record), a 1.14 WHIP (Walks and Hits per Inning Pitched) and a 2.52 ERA (Earned Run Average) which ranks tenth in MLB. Additionally, Logan Webb has tallied a massive 120 strikeouts (fifth in MLB) while allowing 23 walks in 107.1 innings pitched this season.
Earlier this month, in the San Francisco Giants 3-2 win over the Atlanta Braves, San Francisco starting pitcher Logan Webb certainly pitched at a high level. Let me be more specific. Webb pitched six quality innings while scattering six hits and no walks in the Giants win over Atlanta.
In my opinion, Logan Webb is the most likely player to post the most Draftkings points in tonight’s MLB regular season game. Having stated that, I am backing San Francisco Giants starting pitcher Logan Webb 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): Ryan Nelson, Starting Pitcher (Arizona Diamondbacks) $10,400: Rafael Devers, Third Baseman (San Francisco Giants) $9,200: Wilmer Flores, First Baseman (San Francisco Giants) $6,200.
