🏀 St. John's vs. Duke Prediction Tonight: March Madness Sweet 16 Odds & Picks
No. 1 Duke is a 6.5-point betting favorite in its Sweet 16 matchup tonight against No. 5 St. John's, but it’s the total that stands out for me. The Blue Devils’ top-ranked defense is likely to frustrate a St. John's offense that ranks outside the top 40 in efficiency. Tipoff from Capital One Arena in Washington, D.C., is scheduled for 7:10 p.m. ET (CBS).
My St. John's vs. Duke prediction tonight features a trio of Unders: the overall game total, St. John's team total, and Zuby Ejiofor’s scoring prop. These three bets combine for a +220 same-game parlay, capitalizing on Duke’s defensive dominance as part of our March Madness predictions.

🏆 Who will win St. John's vs. Duke?
See the latest March Madness odds for every team in the 2026 NCAA Tournament.
I'm taking Duke to win by seven points. The Blue Devils' top-ranked defense should lock down against a St. John's offense that isn't efficient enough to score with Duke given Duke's ability to limit the number of possessions in a game with a measured tempo.
Score prediction: Duke 70, St. John's 63
🚑 Will Duke's Caleb Foster play against St. John's in Sweet 16?
Duke's Caleb Foster is a game time decision for tonight's Sweet 16 matchup against St. John's. The team's starting point guard has missed the previous five games with a fractured foot.
He practiced on Wednesday. Foster started 30 of Duke's first 31 games and averaged 8.5 points, 3.6 rebounds and 2.8 assists, shooting 40.2% from 3-point range.

Under 142.5 (-110)
If you forced me into it, I'd lean Duke by a hair on this spread--but I'm just not touching this line with the number at 6.5. I prefer to attack what I consider to be a better edge on the total as St. John's (12-23 on Overs) and Duke (12-24 on Overs) both come into this matchup with some of the lowest Over rates in the nation.
Duke has the No. 1 defensive rating in the country, with the Johnnies inside the top 10, per KenPom. St. John's offensive rating is outside the top 40. The Red Storm just isn't efficient enough to get to a requisite point total against this suffocating Blue Devil defense.
We've seen Duke play to totals below 142.5 in 14 of its last 20 games. Even against a faster-paced team with a slightly lesser defense, St. John's mustered only 67 points in the Second Round win over Kansas.

Zuby Ejiofor Under 16.5 points (-120)
St. John's forward Zuby Ejiofor is in for a difficult matchup against Duke as Cameron Boozer's length and strength should mitigate the St. John's big man.
But beyond the specific challenges of that matchup, Ejiofor's scoring line sitting slightly above his season average (16.3 PPG) just feels like a misprice given St. John's team total down at 67.5.
Ejiofor has scored Under 16.5 points in 20 out of 36 games (55.5%), a rate slightly better than the rate of the implied probability (54.55%) associated with these -120 odds from bet365.

🚀 St. John's vs. Duke same-game parlay
Ejiofor's line at bet365 is 16.5 points (Under: -120), while FanDuel has it at 15.5 points (Under: -125). That made the sportsbook selection an easy choice for this parlay, as all three elements are strongly correlated with what I anticipate will be a dominant performance by the Duke defense.

Latest St. John's vs. Duke odds movement and betting splits via BetMGM.
| Market | St. John's | Duke | Betting splits |
|---|---|---|---|
| ↔️ Spread | +6.5 (-110) | -6.5 (-110) | 64% St. John's / 36% Duke |
| ↕️ Total (O/U) | O 140.5 (-110) | U 140.5 (-110) | 72% Over / 28% Under |
| 💵 Moneyline | +230 | -285 | 29% St. John's / 71% Duke |
Nearly two-thirds of spread tickets are on St. John's, but the line hasn't budged from Duke -6.5 - a sign that the money side is comfortable with the Blue Devils at this number. On the moneyline, 71% of tickets are on Duke, which is expected for the tournament's top overall seed.
Despite 72% of bets landing on the Over, the total has dropped two full points from 142.5 at open to 140.5. That's significant reverse movement and a strong signal that the Under side is where the larger wagers are landing.

💡 How I'm betting St. John's vs. Duke: March Madness strategy
I'm betting one unit each on the game total, St. John's team total, and the Ejiofor player prop. I'll allocate a half-unit to the SGP, which combines all three picks, as an attempt to juice up our winnings if we've read this game correctly.
The three picks correlate pretty strongly, so we’ve kept the parlay to a half-unit to limit the potential downside, as one wrong pick could very well imply three losing picks.
📊 Live St. John's vs. Duke odds: March Madness Sweet 16
Duke opened at -6.5 and hasn't moved off that number across our best sports betting sites, with the juice sitting close to even on both sides. A slight push toward Duke is possible, but this line looks locked in.
The total is where the action has been. After opening at 142.5, it's dropped to 140.5 - a two-point slide that aligns with how both teams have played all season. Both Duke (12-24 on Overs) and St. John's (12-23) rank among the lowest Over rates in the country, and the market is pricing that in.
