The Oklahoma City Thunder may have the upper hand in this heavyweight Western Conference finals slugfest, but you can be sure the San Antonio Spurs will come out swinging in tonight’s must-win Game 4.

While mounting injuries are taking a toll, there’s still more than enough available talent to deliver another classic installment of this rivalry.

My favorite Thunder vs Spurs props include another Shai Gilgeous-Alexander masterpiece and a bounce-back effort from Stephon Castle.

Read on for my Top 3 NBA picks ahead of this May 24 showdown.

Game 4 Prop #1: Shai Gilgeous-Alexander Over 29.5 points (-112)

The shooting efficiency numbers don’t reflect it, but Shai Gilgeous-Alexander is putting together an outstanding series.

He made all the right reads in Game 3, and it would be no surprise to see the San Antonio Spurs dial back the double teams and traps tonight after being picked apart by the Oklahoma City Thunder's 3-point shooters.

If that results in more one-on-one coverage, SGA has a path to easier mid-range jumpers — and I expect that to translate to his highest points total of these Conference Finals.

His 30-point effort in Game 2 provides a blueprint, and I’m picking Shai to sense the moment here with a chance to take a stranglehold on the series.

Game 4 Prop #2: Stephon Castle Over 23.5 points + assists (-120)

Stephon Castle brings so much to the table for the Spurs, but injuries to De’Aaron Fox and Dylan Harper have piled even more responsibility onto his plate. Predictably, it’s been a bumpy ride, but Castle isn’t backing down from the challenge.

San Antonio is going to load up all the minutes he can handle, and I expect a better shooting night here after his 1-for-8 dud on Friday, even if he doesn’t hit the heights of his 25-8-5 Game 2 stat line.

Castle has nailed this combo Over in three of his last four outings in these playoffs, and his connection with Victor Wembanyama is always a ticket to a few easy assists.

Game 4 Prop #3: Cason Wallace Over 11.5 points + rebounds (-120)

The Thunder’s depth shone through in Game 3, and they’ll need to shuffle those cards again here with Ajay Mitchell out and Jalen Williams still questionable.

That should mean even more minutes for Cason Wallace and Alex Caruso — and I love this Over for Wallace, who made a pair of huge 3-pointers on Friday.

He’s cashed this prop in all three games of this series, as well as two of the final three contests against the Los Angeles Lakers in the previous round.

With the Spurs leaning on guard-heavy lineups, Wallace’s tenacity on both ends of the floor stands out as an X-factor for OKC tonight.
