NBA Finals Game 4 betting tips: San Antonio Spurs vs New York Knicks predictions and preview

Victor Wembanyama and the San Antonio Spurs breathed new life into the NBA Finals with a 115-111 victory in Game 3, cutting the New York Knicks' series lead to 2-1 ahead of Thursday's Game 4 clash at Madison Square Garden.

After two narrow defeats to open the series, the Spurs finally found their rhythm in key moments, while the Knicks will be looking to avoid letting a commanding advantage slip away on home court. 

Game 4 now shapes as one of the defining contests of the series.

The Knicks remain favourites with bookmakers, but San Antonio's response in Game 3 suggests the gap between these teams may be narrower than the market implies.

All betting lines provided per Betway.

Match winner: Momentum swings towards San Antonio

Winner (Including Overtime)

Knicks – 1.77

Spurs – 2.02

The market still favours New York, largely due to home-court advantage and its 2-1 series lead.

However, Game 3 revealed a few cracks.

Karl-Anthony Towns was limited to just 11 points after playing a major role in New York's first two victories, while Wembanyama delivered his best performance of the Finals with 32 points, eight rebounds and six assists. 

The Spurs also received meaningful contributions from Stephon Castle and Dylan Harper, making them far less reliant on their superstar than earlier in the series.

Jalen Brunson continues to produce points, but his efficiency remains a concern. Through three games, he has often required heavy volume to reach his scoring totals.

The Knicks deserve favouritism, but these odds suggest a wider separation than recent performances indicate.

Prediction: San Antonio Spurs to cause another upset.

Total points: Market expecting a tighter contest

Total Points

Over 215.5 – 1.89

Under 215.5 – 1.85

Game 3 produced 226 total points, while Games 1 and 2 finished on 200 and 209 points respectively.

That creates an interesting split.

The first two games were shaped by playoff intensity and defensive execution, while Game 3 opened up considerably as both teams traded scoring runs throughout.

Neither side has shot particularly well from three-point range in the finals, yet both continue to generate enough quality looks to threaten higher totals.

If Wembanyama maintains his aggressive approach and Towns responds after a quiet outing, this line appears attainable.

Prediction: Over 215.5 total points.

Special market: Overtime remains unlikely

Will There Be Overtime?

Yes – 14.00

No – 1.03

The first three games have all been decided by 10 points or fewer, including a one-point thriller in Game 2.

That naturally creates intrigue around the overtime market.

However, overtime remains a rare occurrence even in closely contested playoff games, and neither team has shown a tendency to play conservatively late in possessions. 

Both Brunson and Wembanyama are willing to take responsibility in decisive moments, often producing a winner before an extra period becomes necessary.

The value may look tempting on the "Yes" option, but probability still favours the game ending in regulation.

Prediction: No overtime.

Final verdict

The pressure sits squarely on New York.

A Knicks victory would restore control of the series and move them within two wins of a championship. 

A Spurs win would level the finals at 2-2 and completely shift momentum before the series returns to San Antonio.

With Wembanyama coming off his strongest performance of the finals and Towns needing a response, expect another tight contest under the lights at Madison Square Garden.

Best bet: Spurs to win (Including Overtime)

Value play: Over 215.5 total points
