Spurs Looking to Force Game 7

They now find themselves in a situation where a loss in either of the next two games ends their season. In Game 5, San Antonio led by eight midway through the first quarter but trailed by two at the end of the stanza. The Spurs tied the game early in the second quarter but quickly gave up 10 of the next 11 points. They never got even again and ended up falling. Stephon Castle led the way for San Antonio with 24 points, five rebounds and six assists in the loss.

Key Injury Report for Spurs:

Thunder vs. Spurs Prediction

Oklahoma City picked up the win in a critical Game 5 situation, giving them two shots at the one win they need to advance. It also restored home court advantage for the Thunder, who persevered slow starts in Games 3 and 5 to earn wins. Mitchell is out again here while Williams again carries the questionable tag. That might solely be for show as it seems unlikely that he’ll suit up. San Antonio needs a better showing from Wembanyama, who scored 20 points but went just four of 15 from the floor. The Spurs are the one team best suited to push the Thunder to the limit. Based on what we’ve seen in the series, expect just that to happen.

Our Prediction: Spurs -3.5 (-110, BetMGM)
