The 2026 NBA Playoffs are heating up, and Saturday, May 9, brings a fresh slate of prop betting opportunities you won't want to miss. With the Thunder holding a commanding 2-0 series lead over the Lakers, all eyes are on reigning MVP Shai Gilgeous-Alexander, who has been nothing short of spectacular from the field.

Gilgeous-Alexander is shooting an impressive 53.6% against Los Angeles, and his scoring prowess has been a key storyline. After finishing second in the NBA during the regular season with 31.1 points per game, his over/under for Game 3 sits at 29.5 points. According to the SportsLine Projection Model, which simulates each game 10,000 times, SGA is projected to surpass that mark with 32 points, making this one of the top prop bets to consider on Saturday.

But the action doesn't stop there. Cavaliers guard James Harden is also drawing attention for his rebounding consistency. Harden has grabbed 14 boards in the first two games against the Pistons, and his over/under for Game 3 is set at 5.5 rebounds. SportsLine NBA expert Doug Kralstein notes, "Harden now has at least six boards in each of his last five games, and has cleared this line in 4 out of 5 matchups against Detroit. The Cavs' defensive scheme keeps him away from primary action, freeing him up to crash the boards effectively."

The SportsLine Projection Model has a proven track record, returning over $10,000 in betting profit for $100 players on its top-rated picks over the past eight-plus seasons. Entering the second round of the 2026 playoffs, the model is on a hot 26-9 roll (74%) on top-rated NBA spread picks. Whether you're a seasoned bettor or new to the game, these insights can help you make smarter choices for Saturday's games.
