Underdog Promo Code TOPACTION: Create Winning Masters and NBA Lineup Now
Create a new DFS account with the Underdog promo code TOPACTION now and build your first lineup today.
The Underdog Fantasy platform offers two types of DFS lineups: Standard and Flex. The Standard lineup provides a 6x payout, where you must win all your picks to profit cash. On the other hand, a Flex lineup offers a 3x payout for a perfect entry or a 1x payout if you get two out of three picks correct.
For my lineup example, here’s what I’m looking at:
Tyrese Haliburton (Indiana Pacers) Higher Than 31.5 Points+ Rebounds+Assists: Haliburton has been the primary playmaker for the Pacers all season, consistently creating opportunities for his teammates. In a fast-paced game against the Grizzlies, expect him to rack up assists as he looks to facilitate the offense.
Anthony Edwards (Minnesota Timberwolves) Higher Than 9.5 Rebounds+Assists: Edwards has been filling up the stat sheet this season, and his rebounding numbers have been strong, especially in high-intensity games. With the Timberwolves facing the Grizzlies, expect him to step up on the glass and hit the rebound mark.
Brooks Koepka (2025 Masters) Higher Than 10.5 Fairways Hit: Koepka has been known for his accuracy off the tee, especially in major tournaments. On the challenging fairways of Augusta, expect him to stay consistent and hit more than 10.5 fairways as he positions himself for a strong performance. With his steady driving, Koepka should be able to control the course and exceed this number.
With the Underdog promo code TOPACTION, you have the opportunity to earn real cash by creating winning fantasy lineups today. Be sure to lock in your NBA picks for today’s action as well as the second round of the Masters Tournament tomorrow. Whether you're making a Standard or Flex DFS lineup, the rewards are substantial.
