How to Use Your Underdog Bonus Tonight

The Oklahoma City Thunder (53-15, 1st in the Western Conference) will take on the Orlando Magic (38-29, 5th in the Eastern Conference) tonight at 07:00 PM EDT.

  • Oklahoma City Thunder Props:
    • Shai Gilgeous-Alexander: Higher/Lower 30.5 Points
    • Chet Holmgren: Higher/Lower 16.5 Points
    • Isaiah Hartenstein: Higher/Lower 8.5 Rebounds
    • Luguentz Dort: Higher/Lower 1.5 3-Point Field Goals Made
    • Alex Caruso: Higher/Lower 6.5 Points
  • Orlando Magic Props:
    • Paolo Banchero: Higher/Lower 21.5 Points
    • Desmond Bane: Higher/Lower 19.5 Points
    • Wendell Carter Jr.: Higher/Lower 10.5 Points
    • Jalen Suggs: Higher/Lower 5.5 Assists
    • Tristan da Silva: Higher/Lower 10.5 Points

When analyzing tonight’s lines to find some hidden value, Shai Gilgeous-Alexander’s points prop of 30.5 immediately jumps off the page. He is entering this matchup riding a historic 128-game streak of scoring 20 or more points. Down low, Isaiah Hartenstein’s rebounding total is set at 8.5. Even with ongoing calf injury management, he just grabbed 12 boards against Minnesota, and it does stand to reason that he is a strong candidate to go higher than this total once again.

On the Magic side, they are looking to bounce back after a tough loss snapped their impressive seven-game streak. Paolo Banchero is looking at a 21.5 points line. He has been averaging 24.2 points over his last 10 games, showing the consistent volume we love to see when projecting higher outputs. Desmond Bane, who has been a pivotal acquisition for Orlando, presents an interesting case with his 19.5 points line. He is averaging 20.6 points recently, making him a prime target.
