NBA Wednesday Night Player Props

Looking at the highest points props on the board, Jaylen Brown tops the list with an over/under of 27.5 points. He faces a Miami Heat squad looking to slow down the dynamic Boston offense. Brown will look to exploit this matchup, while Miami counters with Bam Adebayo, who enters averaging 20.1 PPG (prop set at 19.5 O/U).

Joel Embiid and Tyrese Maxey are also primed for massive performances against the Washington Wizards. Embiid’s 26.5 O/U and Maxey’s 25.5 O/U both offer serious statistical upside against a heavily outmatched defense. They will go up against Wizards center Alex Sarr, who is averaging 16.3 PPG on the season and has his points prop set at 13.5.

Finally, Jalen Brunson boasts a 24.5 points prop against the Memphis Grizzlies. The Grizzlies are currently decimated by 10 active injuries. With Memphis missing a massive portion of their core rotation, Brunson should find plenty of scoring opportunities in what projects to be a heavily tilted matchup.

How to Activate Sleeper Promo Code MHSXL

Unlocking your welcome offer ahead of the April 1, 2026, matchup between the Boston Celtics and Miami Heat is a simple process. Follow these steps to ensure you maximize your bonus value before tip-off:

  • Create an Account: Download the Sleeper app or visit their website, and register for a new account using your standard personal information.
  • Enter the Code: During the registration process, promo code MHSXL is required to qualify for the promotion.
  • Fund Your Wallet: Make your first deposit using one of Sleeper’s secure payment methods. A minimum transaction of at least $10 is required to activate the flat $20 bonus.

Maximizing Your Deposit Match

It is important to remember that Sleeper applies the 100% deposit match strictly to your first deposit. Do not make a $10 initial deposit unless that is the exact amount you want matched. While $10 is enough to secure the $20 sign-up bonus, making a first-time deposit of $100 is how you will receive the full $120 value of the potential Sleeper bonus.

Users do not have to deposit the full $100 to get the deposit match, that is simply the maximum amount Sleeper will match. The promotion scales to your preference. For example, if you decide to deposit $50 to build your Celtics vs. Heat DFS entries, Sleeper will match it with an additional $50 in bonus funds. Plan your initial deposit carefully to ensure you get the exact match amount you want for the NBA action.
