Underdog Promo Code: Offer Details

The newest Underdog promo code is TOPACTION and unlocks $50 in fantasy bonus entries when you play your $5 first entry. Underdog is a leading DFS platform available in 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, and WY.

This offer fits Phillies vs. Dodgers well because the first pitch comes late (10:10 p.m. ET), giving you a second window to build pick’em entries after earlier MLB games wrap. It’s a strong match for new Underdog users and for anyone who prefers DFS pick sets over full lineups, especially if you want to pair one late-night baseball entry with daytime volume like the French Open.

After a $5 play, you unlock $50 in bonus entries, which lets you spread entries across multiple contests rather than forcing one large build. That flexibility is useful on a split-focus Friday when you may want different entry styles in the same fantasy app. Make sure to use the Underdog bonus code TOPACTION during account registration to lock in the offer.

How to Use Underdog Welcome Bonus on Phillies vs. Dodgers

Start with your $5 play to unlock $50 in Bonus Entries, then use those credits as entry-fee fuel for Phillies-Dodgers builds. Bonus Entries cover contest entry fees, but they’re separate from withdrawable cash, so treat it as more chances to test different pick sets, not cash added.

Here’s a clean way to allocate the $50 from the Underdog promo code TOPACTION for tonight, with simple math that keeps you flexible around a late 10:10 p.m. ET lock:

  • Path A: One focused $50 entry built around Phillies-Dodgers. Your $50 Bonus Entries cover the full $50 entry fee, and your out-of-pocket stays at $0 after the initial $5 play.
  • Path B: Five $10 entries split across MLB and the French Open to test different builds. Your $50 Bonus Entries cover all five $10 entry fees ($50 total). If you want to scale to $100 in total entries, add five more $10 entries and you’d pay the extra $50 out-of-pocket.

Timing works in your favor tonight: get your earlier tennis entries in first, then come back to finalize your Phillies-Dodgers picks closer to lock once lineups and any late news settle.
