The San Antonio Spurs wrapped up the Western Conference semifinals with a Game 6 victory over the Minnesota Timberwolves, but they’ll face a stiffer task when they face the undefeated Oklahoma City Thunder in the Western Conference Finals.
My Spurs vs. Thunder predictions call for a low-scoring matchup between two defensively gifted teams looking for a key opening victory.
Here are my best free NBA picks for Game 1 from Paycom Center on Monday, May 18.
Spurs vs Thunder Game 1 prediction
Spurs vs Thunder best bet: Under 219 (-110)
The San Antonio Spurs boast the best defensive rating in the playoffs at a paltry 102.2, and the Oklahoma City Thunder rank sixth at 109.3.
The Spurs have surrendered just 102.5 points per game, while the Thunder have given up 104.6. Opponents are shooting just 40.5% against the Spurs, the lowest mark in the NBA.
Oklahoma City ranks second in opponent turnovers and third in steals, and they can disrupt San Antonio’s rhythm and potent scoring attack.
I’ll take the Under as these powerhouses trade blows and make life difficult for one another on offense.

Spurs vs Thunder Game 1 same-game parlay
The Spurs have won and covered seven of their last 10 games, and all three of their losses came by five points or fewer. The Thunder are 5-3 ATS in the postseason, but they haven’t yet faced a team that is this familiar with them. The Spurs can keep things close on the road.
Victor Wembanyama has recorded 14+ rebounds in five of his last six games with at least 20 minutes played. Game 1 against the Thunder should be close, and Wemby’s rebounding will be needed against the Thunder’s two-headed monster of Chet Holmgren and Isaiah Hartenstein.
