New users who sign up with Underdog promo code TOPACTION stake a $5 entry and collect $50 in bonus entries, win or lose.
First pitch already passed on much of Wednesday's MLB card, but Underdog keeps player projections open right up until each game starts. Late slate games and West Coast first pitches leave plenty of room to lock in a lineup.

Where Underdog Promo Code TOPACTION Works
Underdog's pick'em product covers a wider map than most operators, so the footprint looks nothing like the standard answer to where sports betting is legal. The code unlocks 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.
California and Texas players rank among the biggest winners here, since both states sit outside the legal sportsbook map entirely.
Wednesday MLB Picks: Three Home Run Swings
Home run projections carry the fattest multipliers on the board, which makes them a natural fit for bonus entries. These three MLB picks stack the sport's most dangerous power bats into one high-upside entry:
- Ronald Acuña Jr. Higher 0.5 Home Runs: Mets starter Zac Thornton is a prime negative-regression candidate, with a 4.63 xERA far above his 2.52 ERA and batted-ball luck masking his hard contact allowed. While Acuña has hit just .196 over the past 15 days, his elite 13.6% barrel rate and frequent 100-plus mph exit velocities suggest better results are coming, making him appealing against Thornton and a depleted Mets bullpen.
- Corey Seager Higher 0.5 Home Runs: Corey Seager’s poor batting average masks strong underlying contact, with a 14.4% barrel rate and multiple 98-plus mph hits suggesting a breakout is coming. He draws a favorable matchup against George Klassen, whose 26.9% walk rate, 13.8% barrel rate allowed and 7.80 xERA make him vulnerable to Seager’s power.
- Bobby Witt Jr. Higher 0.5 Home Runs: Bobby Witt Jr. has shown strong contact since returning from injury and appears due for positive regression, with a .303 xBA and .509 xSLG far exceeding his actual marks. He also excels against lefties and draws a favorable matchup against Eric Lauer, who has a 11.4% barrel rate and has allowed a homer in 15 of 18 appearances.
Stack all three in a single higher entry for the maximum payout, or split them across separate entries to spread the risk.
Why Underdog Ranks with the Top DFS Sites
Underdog's interface loads fast on mobile, the boards refresh throughout the day, and the higher/lower format skips the salary cap math that slows down traditional lineups. Same-game stacking on MLB DFS boards keeps things simple for anyone new to the format.
