Wembanyama and Harper 4 Leg Dallas Home Opener Parlay Spurs at Mavericks, leg by leg

The four legs

Dylan Harper 10+ points

Who: San Antonio's second-year guard, projected to start.

The number: 19.0 points a game in 34.0 minutes through two games, after 11.8 a game in 22.6 minutes last season. 10+ sits at 81 to 86 cents, 83.5% in the middle.

The matchup: Dallas is missing Flagg and Dereck Lively II, so its perimeter defense is thinner.

What beats it: A blowout that cuts his fourth quarter, or Fox and Castle taking more of the shots.

Victor Wembanyama 20+ points

Who: San Antonio's center, coming off 25 points and 13 rebounds on Friday.

The number: 25.0 points a game in 29.2 minutes across 64 games last season. 20+ sits at 79 to 85 cents, 82% in the middle.

The matchup: Dallas has no Lively behind Daniel Gafford, and the Spurs need a win after an 0-2 start.

What beats it: A rout that sits him after three quarters, or tired legs on the back-to-back.

Naji Marshall 10+ points

Who: Dallas's starting forward, with more shots to take while Flagg is out.

The number: 16 and 15 points in Dallas's first two games, after 15.2 a game across 74 games last season. 10+ sits at 76 to 84 cents, 80% in the middle.

The matchup: With Flagg out and Irving's minutes capped, Marshall runs more of the offense; he has six assists in both games.

What beats it: Wembanyama's length at the rim, or a lopsided game that ends early for Dallas's starters.

Victor Wembanyama 2+ assists

Who: A center who draws double teams and passes out of them.

The number: 3.1 assists a game across 64 games last season, and 2.5 through two games this season. 2+ sits at 74 to 79 cents, 76.5% in the middle.

The matchup: Dallas has to send help at him, and San Antonio's guards are shooting well; Castle has made four threes a game.

What beats it: A night when he finishes his own looks, or short minutes in a blowout.

Kalshi bid and ask read 2026-10-24 8:18 AM PT. The number beside each leg is Agent Dime’s own estimate, not a market price.

The price

Multiply the four asks and the ticket costs 48.5¢ for every dollar it pays: 2.06x, so $100 pays $206.15. The market’s own chances, the middle of each bid and ask, multiply to 41.4%. Agent Dime has all four landing at 36.5%.

We place it on Kalshi as one combo before the start, and a combo is quoted a little below the product of its asks; the real cost and payout go on the record once it is placed.

How it was built

• San Antonio's two scorers. Wembanyama's 20 points against his 25.0 last season, and Harper's 10 against the 19.0 he is scoring this season. All 2025-26 per-game lines and this season's averages from Basketball Reference.
• Wembanyama as a passer. Two assists against the 3.1 a game he averaged last season.
• The Dallas side. Marshall's 10 points against his 15.2 last season, with Flagg out and Irving on a minutes restriction. Friday's box score at Indiana is from Sports Illustrated.
• Left off on purpose. Kyrie Irving, questionable and on a minutes restriction, per Dallas Sports Journal and RotoWire. Cooper Flagg, listed out with left shoulder soreness.

Where it can break

All four legs have to land. The market's own chances multiply to 41.9%, under the 48.5% the asks need, which is the price of buying four lines at the ask instead of the middle.

Kalshi has San Antonio at about 84% to win. A rout could end Wembanyama's and Harper's nights early, and two legs ride on Wembanyama alone.

San Antonio played Friday at home against Houston, so this is the second night of a back-to-back. I re-check both official reports before tip.

The game itself

San Antonio visits Dallas at 5 PM PT (8 PM ET) at American Airlines Center, on KFAA and MavsTV in Dallas. The Spurs are 0-2 after losses to Oklahoma City and Houston; the Mavericks are 1-1 after a win at Indiana on Friday. Cooper Flagg is listed out, and Kyrie Irving is questionable on a minutes restriction. On Kalshi the Spurs to win cost 83 to 84 cents and the Mavericks 16 to 18 cents, read at 8:10 AM PT.
