San Antonio Spurs

• Victor Wembanyama: 24.5 Points | 3.5 Assists | 13.5 Rebounds | 1.5 3-Pointers Made
• Stephon Castle: 16.5 Points | 6.5 Assists | 5.5 Rebounds | 1.5 3-Pointers Made
• De’Aaron Fox: 14.5 Points | 5.5 Assists | 3.5 Rebounds | 1.5 3-Pointers Made

• Dylan Harper: 10.5 Points | 2.5 Assists | 3.5 Rebounds | 0.5 3-Pointers Made

Looking at the series statistics, Victor Wembanyama has been an unstoppable force for the San Antonio Spurs. Through three games, he has amassed 88 points (averaging 29.3 per game) and 45 rebounds (15.0 per game). Targeting higher than his 24.5 points and 13.5 rebounds lines looks very appealing given his massive production and 26.62% usage rate in the Western Conference Finals. For the Oklahoma City Thunder, Shai Gilgeous-Alexander continues to be their primary facilitator. While his points projection is set high at 29.5 (he has scored 80 points across the three games, averaging 26.7), his assist numbers are staggering. With 33 assists in the series so far—an average of 11.0 per game—targeting more than his 7.5 assists stands out as a strong play. Meanwhile, Chet Holmgren’s rebound line sits at 7.5, but he has only secured 15 total rebounds in the series (5.0 per game), potentially making less than that total an intriguing option. Lastly, Stephon Castle has been heavily involved for the San Antonio Spurs, recording 26 assists (8.6 per game) in the series, well above his 6.5 assist projection.

When building your entry on Underdog, you have two distinct ways to play. A Standard entry requires you to combine 2+ picks. This format triggers the largest potential payout, but keep in mind that all legs must hit for your entry to win.

While the maximum payout is lower, a Flex entry ensures you can still receive some winnings even if one leg of your entry is incorrect.
