Unlike the many of the nation's best sportsbooks, Underdog Fantasy is a DFS operator. This means you set a lineup rather than place traditional sports bets. With Underdog, you can have a lineup of up to five picks from any of the MLB playoff series, including the New York Mets vs. Milwaukee Brewers series or Detroit Tigers vs. Houston Astros series. Simply select "Higher" or "Lower" on specific statistical categories for each player pick. The more selections you make, the higher the potential payout.
As a DFS operator, the Underdog Fantasy promo code TOPACTION is available in AK, AL, AR, CA, DC, GA, IL, IN, KS, ME, MN, MS, NC, ND, NE, NM, NY, OK, OR, RI, SC, SD, TX, UT, VA, VT, WY, and WI.
How to Use the Underdog Fantasy Promo Code TOPACTION for the MLB Wild Card Picks
When you sign up with the Underdog Fantasy promo code TOPACTION and make your first deposit, you get bonus cash instantly. With the MLB Playoffs now underway, it's an excellent time to set a lineup for the Wild Card Round.
Before that, let's review the payout breakdown. Underdog Fantasy breaks lineups down into two categories: Flex and Standard. With the former (Flex), you get a payout even if all your selections don't hit. If you select the latter (Standard), every pick in your lineup must hit to get the payout.
Underdog Fantasy Standard Lineup Payout
- Two picks: 3x
- Three picks: 6x
- Four picks: 10x
- Five picks: 20x
So, if I deposit $300, I get $150 in bonus cash. From there, I put down $80 on a three-pick standard lineup:
- Tarik Skubal Higher than 6 Strikeouts
- Jose Altuve Higher than 1.5 Total Bases
- Bobby Witt Jr. Higher than 0.5 Home Runs
With a standard lineup, if all of those picks hit, I get a $480 payout. If just one pick misses, I lose my original stake.
To meet the playthrough requirement, I need to play $450 over the following 60 days to be able to withdraw any winnings.
