Thunder Spurs Game 3: Jared McCain Drops 24 as OKC Bench Buries San Antonio 123-108

Seventy-six bench points. That is what the Oklahoma City Thunder hung on the San Antonio Spurs in a 123-108 Game 3 win at Frost Bank Center on Friday night, the franchise's highest playoff bench-scoring total since the team relocated to OKC in 2008-09. Without Jalen Williams (left hamstring, out), the defending champs leaned on a 24-point night from Jared McCain, 18 from Jaylin Williams, and a 26-and-12 line from Shai Gilgeous-Alexander to take a 2-1 series lead.

Victor Wembanyama countered with another monster stat line, but the Thunder's depth flipped the math. San Antonio's bench was outscored 76-23 in a series where margins are running thin. Game 4 is Sunday night in San Antonio, and the line has already moved.

What Happened

OKC trailed early. The Spurs jumped out in the first quarter and held a lead into the second behind a balanced attack from Wembanyama and Dylan Harper. Then the Thunder bench hit. McCain, the 22-year-old guard acquired from Philadelphia in a midseason swap for a 2026 first and three future seconds, scored 24 on efficient looks and stretched the floor in ways San Antonio could not match. Jaylin Williams added 18, Alex Caruso 15, and Cason Wallace chipped in 11.

The Thunder's reserves accounted for more than 60 percent of the team's scoring. That is unusual in a conference final. It is also a problem San Antonio has not solved through three games, and the Spurs are now staring at a Game 4 they must win at home to keep the series competitive.

Shai Gilgeous-Alexander finished 8-for-19 from the floor but 12-for-12 from the line, hunted his spots, and dished 12 assists. He took 14 free throws in a hostile building, and the Frost Bank crowd's "floop-er" chants did not faze him.

The Numbers

Game 3 box score highlights from ESPN and NBA.com:

1. Thunder bench 76, Spurs bench 23. A 53-point delta in a 15-point game. 2. Jared McCain: 24 points off the bench, his most as a Thunder player. 3. Jaylin Williams: 18 points, key stretch minutes when SGA sat. 4. SGA: 26 points, 12 assists, 12-of-12 from the line. 5. Wembanyama: still posted a heavy stat line, but the math did not work in his favor without secondary support. 6. McCain is shooting 39.1 percent from three across 30 regular-season games with OKC since the trade.

The bench production matters because the Thunder were 7-2 in regular-season games where Jalen Williams sat. Mark Daigneault keeps stacking minutes for the second unit, and they keep cashing.

Betting and DFS Impact

Series price moved hard. Going into Game 3, OKC sat around minus-185 to win the series at FanDuel. After Friday's result, books re-listed the Thunder at roughly minus-360 to advance, with San Antonio drifting to plus-260 (FanDuel, May 23 morning). The Game 4 spread opened with OKC favored by 2.5 to 3 in San Antonio, depending on book, with a total around 224.5.

Three angles worth flagging for the Sunday slate:

1. McCain over 12.5 points. He has cleared this in two of his last three playoff appearances, and the role is only getting bigger with Jalen Williams in street clothes. 2. Wembanyama assists prop. With San Antonio's bench torched in Game 3, Gregg Popovich may run more offense through Wemby as a hub. His assists over has been a quiet edge all series. 3. Live first quarter total under. OKC has started slow in two of three games this series, then run away after halftime. Live unders on the opening 12 have been printing.

Jalen Williams and the Game 4 Question

Jalen Williams was ruled out for Game 3 with a left hamstring strain, the second time in under a month he has aggravated the same injury (the first was April 22). The Thunder say he is day-to-day. Per [ESPN's report](https://www.espn.com/nba/story/_/id/48838099/

What to Watch Next

Game 4 is Sunday, May 24, in San Antonio at 8 p.m. ET on ESPN. Three things to track between now and tip:

1. Jalen Williams status. Even a partial return at reduced minutes would change OKC's closing lineups. 2. Spurs bench response. Pop has to find production from someone outside the starting five. Stephon Castle and Keldon Johnson are the most likely candidates. 3. The Wembanyama usage shift. If the Spurs run more through Wemby in the post and at the elbow, his counting stats stay big, but the lineups around him need to make threes.

OKC is now four wins from a repeat. San Antonio needs to win Sunday or the series likely ends in five.
