FanDuel Best MLB DFS Picks: Mariners vs. Rangers 6/29/25

Later today, Major League Baseball presents FanDuel baseball fans with an American League matchup featuring the Seattle Mariners and the Texas Rangers. Let’s take a look at this MLB game from a DFS perspective.

Before we dive into the Seattle Rangers vs. Texas Rangers game let’s review the rules for the FanDuel single game showdown contest.

FanDuel Single Game Contest Rules

Here are the FanDuel single game contest rules. You have $60,000 to utilize on five players from either team. However, one of those players will be designated as your team MVP. The MVP accumulates 1.5x times the standard FanDuel fantasy points value. Additionally, the MVP is 1.5 times the standard cost of the flex position.

The remaining five players in your lineup will be flex plays. The five flex positions will receive the standard FanDuel points value. Having stated that, it is highly important for you to identify the correct player for your MVP position if you hope to win a large field GPP (guaranteed prize pool) FanDuel single game contest.

If you have additional questions regarding the rules for the single game contest, I highly recommend that you check out the FanDuel website for more details.

*It should be noted that FanDuel does not utilize the pitcher position in single game MLB contests. Having stated that, only batters are available for single game MLB lineups on the FanDuel platform.

Here are my FanDuel picks for this today’s Mariners vs. Rangers matchup.

FanDuel MLB Player Selections

MVP-Corey Seager, Shortstop, Texas Rangers $9,200

On Sunday afternoon, Major League Baseball presents the final game of a three-game American League series featuring the Seattle Mariners and the Texas Rangers.

How are these two teams playing entering today’s MLB game? The Texas Rangers arrive at the third game of this three-game series with the Seattle Mariners playing quality baseball. The Rangers have won three of the team’s last four games played in the 2025 MLB regular season, including a 7-0 shutout win over the Baltimore Orioles four days ago.

In direct contrast to the Texas Rangers, the Seattle Mariners are not playing well entering this afternoon’s American League game. More specifically, the Mariners have lost three of the team’s last four games played in the 2025 MLB regular season, including a 2-0 loss to the Minnesota Twins earlier this week.

Now that we have determined how both of these teams are currently playing let’s shift our attention to today’s contest. Shortstop Corey Seager has certainly been an essential part of the Texas Rangers starting lineup this season. With that said, how has the veteran shortstop performed from a statistical perspective? Let’s examine Seager’s relevant game data from the 2025 MLB regular season to answer that question.

Texas Rangers shortstop Corey Seager arrives at tonight’s game with a .242 batting average, eight home runs, 18 RBIs (runs batted in) and 25 runs scored in 54 games played this season.

More recently, in Texas Rangers 6-2 victory over the Chicago Cubs in April, Texas shortstop Corey Seager played rather well. In the Rangers win over the Cubs, Seager compiled two hits, two RBIs, two runs scored and two home runs. It should also be mentioned that in the Rangers defeat of the Cubs, Seager tallied a massive 28.1 FanDuel points.

In my view, Corey Seager is the most likely player to post the most FanDuel points in tonight’s MLB game. With that said, I am rolling with Texas Rangers shortstop Corey Seager at the MVP position for this one game MLB DFS slate.

Flex plays I like in this game (FanDuel price noted): Cal Raleigh, Catcher (Seattle Mariners) $16,400: Randy Arozarena, Outfielder (Seattle Mariners) $11,400: Evan Carter, Outfielder (Texas Rangers) $10,800.
