Ways to Use the Underdog Promo for March Madness
I’m looking closely at tonight’s matchups to build my entries. The markets have zeroed in on several elite scorers with serious offensive potential. Here are the five players with the highest points over/under lines on the board:
- Dominique Daniels Jr., California Baptist Lancers vs. Kansas Jayhawks — 21.5 points O/U
- Darryn Peterson, Kansas Jayhawks vs. California Baptist Lancers — 21.5 points O/U
- Mark Mitchell, Missouri Tigers vs. Miami (FL) Hurricanes — 18.5 points O/U
- Zuby Ejiofor, St. John’s Red Storm vs. Northern Iowa Panthers — 17.5 points O/U
- Malik Reneau, Miami (FL) Hurricanes vs. Missouri Tigers — 17.5 points O/U
The spotlight tonight is glaring on Viejas Arena in San Diego, where we have a must-watch matchup between No. 13 seed California Baptist and No. 4 seed Kansas. Fans are buzzing about a potential Cinderella story for the Lancers, led by their 5-foot-10 bucket-getter, Dominique Daniels Jr.
He’s fresh off a 41-point outburst in the WAC semifinal and shares a slate-high 21.5-point projection tonight. He’ll be going head-to-head with Kansas freshman Darryn Peterson, a projected No. 1 NBA Draft pick. This is going to be an explosive offensive showcase.
Over at the Enterprise Center in St. Louis, we’re handicapping a heavyweight clash of dynamic forwards. The No. 10 seed Missouri Tigers meet the No. 7 seed Miami (FL) Hurricanes in what promises to be a physical battle. Missouri’s Mark Mitchell (18.5 points O/U) has been on a tear with recent 32-point games, while Miami plans to use their All-ACC senior Malik Reneau (17.5 points O/U) to match his aggression inside.
Finally, don’t sleep on St. John’s forward Zuby Ejiofor. The Big East Player of the Year boasts a game-high 17.5-point line against the Northern Iowa Panthers. He’s been leading the Red Storm’s incredible hot streak under Rick Pitino, making him a fantastic anchor for any entry.
How to Activate Your Underdog Offer
Ready to build your postseason lineup and chase a nice pay day? Claiming this Underdog offer is a straightforward process. Follow these steps to unlock your bonus:
- Register your account: Create a new account here using your standard personal information. Remember, you must be a new user and meet all local age and region requirements to be eligible.
- Use the promo code: Make sure the promo code WTOP is applied during the registration process. This is the key to qualifying for the promotion.
- Fund your wallet: Make a first deposit of at least $5 using one of the platform’s secure payment methods.
- Submit your entry: Play a $5 entry on tonight’s college basketball slate (or any other sport) to officially activate your $50 in bonus entries.
When you’re putting together your picks, you have to decide how you want to structure your wager. This is where we can get a bit strategic. You have two primary options:
- Standard Entry: Select 2 or more picks to trigger the largest potential payout. Keep in mind, for a Standard Entry to win, all of your legs must hit. It’s a bit riskier, but the reward is fantastic if you key in on the right players.
- Flex Entry: If you build a lineup with 3 or more picks, you can choose the Flex option. I love this for complex bets because it provides a safety net—you can still receive some winnings even if one of the legs in your entry is incorrect. It’s a smart way to protect your bankroll while still going for a solid return.
