I'm taking the Underdog promo code TOPACTION into Monday night's Phillies vs. Cardinals, and it's about as easy an entry point as fantasy gets. Sign up, make a $5 play, and Underdog hands you $50 in bonus entries. First pitch for this MLB matchup is 7:45 p.m. ET on FS1 from Busch Stadium in St. Louis.
Underdog is a daily fantasy app built around Pick'em, so you take player stat projections higher or lower and stack them into an entry, with no head-to-head lineup drafting to deal with. That's the format I want for a single game like this one, where I can build a slip around the arms and bats actually on the field instead of chasing a full slate. Enter the Underdog promo code TOPACTION at sign-up and the $50 in bonus entries appears in your account your first $5 submission.

How I'd Use Underdog Promo Code TOPACTION on Phillies vs. Cardinals
So how would I actually use the bonus entries from the Underdog promo code TOPACTION? With just one game to work with, I'd keep it simple and build a little Pick'em slip around the MLB picks I trust the most. The nice part about the $50 bonus is that you're not stuck riding one entry. You can run the same read across a few slips and give yourself more than one crack at winning.
Below is the kind of three-pick lineup I'd throw together tonight, and it leans into the Phillies since that's the side I already like. The projections shift all day, so check what they look like on the app before you make any MLB picks.
Sample Underdog Pick'em lineup (3-pick, Phillies vs. Cardinals):
- Andrew Painter to get Higher, 5.5 strikeouts. His velocity is back near 97 and swing-and-miss has always been his calling card, so I want the Ks on the higher side.
- Bryce Harper to get Higher, 1.5 total bases. Philly's best bat in a spot I'll happily pay up for against the Cardinals' righty.
- Trea Turner to get Higher, 1.5 total bases. He sets the table at the top of the order and adds a second Phillies bat without doubling up on the exact same outcome.
