The San Antonio Spurs and the Oklahoma City Thunder duke it out in Game 1 of the Western Conference Finals at the Paycom Center on Sunday night.


San Antonio Spurs Betting Preview 


The San Antonio Spurs enter this matchup with plenty of confidence as they cruised past the Trail Blazers in the First Round before outlasting the Timberwolves in a six-game series in the Conference Semifinals. Victor Wembenyama has been sensational for the Spurs during these playoffs with averages of 20.3 points, 10.7 rebounds and 4.1 blocks per game, Stephon Castle is averaging 19.9 points, 4.9 rebounds and 6.1 assists per game, De’Aaron Fox is averaging 18.8 points and 5.8 assists per game while Dylan Harper is averaging 13.7 points, 5.1 rebounds and 2.2 assists per game. As a team, the Spurs are scoring 116.9 points per game while shooting 49.0 percent from the field and 38.4 percent from the 3-point line. The Spurs enter this matchup as the underdogs, but they will be quietly confident of their chances as they are the only team in the league to beat the Thunder four times out of five meetings during the regular season. 


Oklahoma City Thunder Betting Preview 


Meanwhile, the Oklahoma City Thunder head into this contest as the favorites which isn’t surprising given that they are the defending champions with the best record in the regular season. The Thunder have maintained their elite level of defense all season and they have yet to be truly challenged in these playoffs after sweeping the Suns and the Lakers to book their tickets to the Western Conference Finals. Shai Gilgeous-Alexander has been rock solid for the Thunder so far in these playoffs as he is averaging 29.1 points and 7.1 assists per game, Jalen Williams has played just two games with averages of 20.5 points and 5.0 assists per game, Chet Holmgren is averaging 18.6 points and 9.1 rebounds per game, while Ajay Mitchell has been a real gem for the Thunder as he is averaging 18.8 points, 4.0 rebounds and 4.9 assists per game. As a team, the Thunder are scoring 121.3 points per game while shooting 51.0 percent from the field and 38.4 percent from the 3-point line.


San Antonio v Oklahoma City Free Prediction


The Spurs could be shorthanded for the series opener as they are still keeping an eye on De’Aaron Fox and Luke Kornet who are both questionable, while the Thunder have ruled out Thomas Sorber again. The Spurs looked incredible in their last two games which resulted in blowout wins over the Timberwolves, but the Thunder have been absolutely rock solid from the very start and have yet to drop a game in these playoffs. The Spurs had plenty of success against the Thunder during the regular season as they were able to limit their turnovers which made it much harder for the Thunder to go on the big runs to take the game away. You can make an argument for either side in this one, but the line just seems a tad too high, so I will happily lean with the Spurs to pull off the upset or at least take this one down to the wire on the road.

Peter Tran's Pick: San Antonio +6.5
