May 12, 2025 9:45 pm EDT
Major League Baseball presents Draftkings baseball fans with a National League matchup featuring the Arizona Diamondbacks and the San Francisco Giants. Let’s take a look at this MLB game from a DFS perspective.
Before we dive into the Arizona Diamondbacks vs. San Francisco Giants 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 Diamondbacks vs. Giants matchup.
Draftkings MLB Showdown Picks
Captain-Merrill Kelly, Starting Pitcher, Arizona Diamondbacks $11,400
On Monday night, Major League Baseball presents the opening game of a three-game National League series featuring the Arizona Diamondbacks and the San Francisco Giants.
How are these two teams playing entering tonight’s National League contest? The Arizona Diamondbacks arrive at the first game of this three-game series with the San Francisco Giants playing below average baseball. The Diamondbacks have lost four of the team’s last seven games played in the 2025 MLB regular season, including a 14-11 loss to the Los Angeles Dodgers three days ago.
Similar to the Arizona Diamondbacks, the San Francisco Giants are not playing well entering this evening’s game. The Giants have lost three of the team’s last four games played in the 2025 MLB regular season, including a 3-1 defeat to the Minnesota Twins last week.
Now that we have identified how both teams are currently playing let’s turn our attention to tonight’s game. Talented starting pitcher Merrill Kelly has been a solid performer for the Arizona Diamondbacks this season. With that said, how has Kelly performed from a statistical perspective? Let’s examine Kelly’s relevant game data to answer that question.
Through eight starts made for the Arizona Diamondbacks this season, starting pitcher Merrill Kelly has compiled a robust 4.09 ERA (Earned Run Average), a 1.05 WHIP (walks, hits, inning pitched). It should also be noted that Kelly has tallied 33 strikeouts while allowing 12 walks in 48.2 innings pitched in 2025.
Last month, in the Arizona Diamondbacks dominant 10-4 victory over the Miami Marlins, Merrill Kelly certainly pitched at a high level. Kelly pitched 6.1 quality innings striking out nine Los Angeles batters while scattering five hits and no walks in the Pirates win over the Dodgers. I think it’s fair to say that Skenes is getting it done on the mound in 2025.
What did we learn from the data just presented? The data tells us that Merrill Kelly is pitching rather well entering tonight’s National League clash with the San Francisco Giants. Having stated that, I am rolling with Arizona starting pitcher Merrill Kelly at the captain position for this one game MLB Draftkings Showdown contest.
Flex plays I like in tonight’s game (Draftkings price noted): Justin Verlander, Starting Pitcher (Houston Astros) $11,000: Heliot Ramos, Outfielder (San Francisco Giants) $6,600: Josh Naylor, First Baseman (Arizona Diamondbacks) $8,000.
