Ten MLB games remain on Monday's board after the afternoon opener in Cincinnati, and new players get a cheap way into the night slate.
Sign up with Underdog promo code TOPACTION, play $5, and collect $50 in bonus entries. That combination ranks as the best MLB DFS promo available for a Monday this size, and it covers every remaining game instead of one matchup.
Eligible states: AL, AK, AR, CA, DC, FL, GA, IL, IN, KS, ME, MS, MN, NE, NM, NC, ND, OK, OR, RI, SC, SD, TX, VT, VA, UT, WI, WY.

Why Underdog Promo Code TOPACTION Works on a 10-Game Board
A wide slate rewards volume. The Underdog promo code TOPACTION turns one $5 entry into $50 in bonus entries, which spreads Monday picks across more games instead of one card.
That math explains why this ranks as the best MLB DFS promo on the board right now. Few top DFS sites match a 10x return on a $5 qualifying play.
The Cincinnati nightcap adds value too. Game 2 of a doubleheader shifts bullpen roles and pitch counts, which moves projections in ways season-long stats miss.
Colorado hosts the late game, and Coors Field always changes hitter and pitcher numbers. Treat that one separately from the rest.
Three Underdog Pick'em Picks for Monday
- Diamondbacks to Win (+113): This pick isn’t about Mitch Bratt, whose below-average pitch modeling, quiet arsenal, and shaky MLB walk rate make him unappealing. Arizona and Boston project nearly identically, but the D-Backs hold slight edges in offense, contact, power, and defense, making them a coin flip on a neutral field.
- Braves-Twins Higher Than 9.5 Runs (+104): I like the Over, with both Martín Pérez and Bailey Ober grading as below-average starters and underlying metrics suggesting Pérez’s sub-3.00 ERA is unsustainable while Ober profiles closer to replacement level. With strong offenses, particularly Minnesota against left-handed pitching, and a vulnerable Twins bullpen, I project the total around 10.
- Freedie Freeman Higher Than 0.5 Home Runs: Tomoyuki Sugano has been a complete gas can for lefty power this season and in his career, giving up a 2.52 HR/9 this season and 2.13 HR/9 last season. This ballpark is one of the best in the majors for power, and the weather should be good for hitting, with temps in the mid-80s. Freeman isn't the same power hitter he used to be, but he still has decent pop.
Pair these three with the $50 in bonus entries from the Underdog promo code TOPACTION rather than loading them onto a single card.
How the $5 Entry Unlocks $50 in Bonus Entries
Sign up, apply the code, then put $5 into a qualifying MLB pick'em contest. Here is how each outcome shakes out.
| Step | Action | Result |
|---|---|---|
| 1 | Apply TOPACTION at sign-up | Code attaches to the new account |
| 2 | Enter a $5 MLB pick'em contest | Offer requirement clears |
| 3 | First entry hits at 2x | Account shows $10 back, entry fee included |
| 4 | First entry misses | The $5 settles as a loss, then $50 in bonus entries posts |
Either way, the $50 arrives after settlement. Spread it out: five $10 entries or ten $5 entries across separate games.

Monday MLB DFS Notes
Start with lineup cards. Batting order spots move projections more than season-long numbers on a single Monday board.
Check pitcher workload next. Recent pitch counts, days of rest, and weekend bullpen usage matter most for the Cincinnati nightcap.
Pull the MLB weather report before locking anything. Wind direction in Chicago and Boston swings total bases and home run markets more than most players expect.
Then sort by park. Cincinnati, Chicago, and Denver play differently than Tampa Bay or New York, and those gaps show up in hits, total bases, and pitching outs.
Common stat categories on Monday's board include pitching outs, hits allowed, strikeouts, hitter total bases, and fantasy points. Underdog lists the exact markets in the app.
