This is the moment we’ve all been waiting for. Tipping off Monday night, the reigning NBA champion Oklahoma City Thunder will host the San Antonio Spurs — the lone team to truly test them this season — in Game 1 of the Western Conference Finals at Paycom Center.

Oklahoma City remains undefeated this postseason after back-to-back sweeps of the Suns and the Lakers. Leading the charge is superstar guard Shai Gilgeous-Alexander, freshly crowned the league’s MVP for the second straight season. The Thunder will lean heavily on SGA in this heavyweight clash, looking to overcome their season-long kryptonite.

Tipoff is set for 8:40 p.m. ET. Oklahoma City is a 6.5-point favorite with -245 moneyline odds, while San Antonio is a +200 underdog. Ahead of Game 1, let’s dive into the top SGA prop bet on DraftKings Sportsbook.

Best Shai Gilgeous-Alexander Prop Bet for Spurs vs. Thunder Game 1

Best Bet: Shai Gilgeous-Alexander Under 4.5 Rebounds (-145)

Shai Gilgeous-Alexander heads into the Western Conference Finals, hot on the heels of becoming just the 14th player in NBA history to win back-to-back MVPs. Last season’s scoring champ averaged 31.1 points and 6.6 assists per game to orchestrate another brilliant campaign for Oklahoma City. However, Gilgeous-Alexander’s glass-cleaning numbers noticeably dipped from 5.0 boards per contest last season to just 4.3 boards in 2025–26. 

That number has continued to drop during the playoffs. 

The four-time All-Star, 27, is averaging just three rebounds across Oklahoma City’s eight playoff games. He has pulled down more than 4.5 boards in only one postseason matchup so far — Game 2 of the opening round against the Suns.

Phoenix and Los Angeles are not known for their interior presence, ranking 12th and 13th, respectively, in rebounds per game among the 16 playoff teams. Now, the Thunder will face a whole different beast in San Antonio, anchored by 7-foot-4 monolith Victor Wembanyama. The Spurs head into the Conference Finals with the top defensive rating and best rebounding numbers of any team to reach the postseason.

With SGA being largely a non-factor on the boards so far, don’t expect him to turn things around in this nightmare matchup against the formidable Spurs.
