CBB Parlay Picks Today - Friday, March 20

We've selected these picks using a combination of Dimers CBB best bets and game predictions to find a combination of value and probability that gives us the best chance to win our CBB parlay.

Today's parlay targets a pair of moneyline upsets on two teams predicted with a Dimers edge to cover the short spreads, and projected with a top probability among underdogs for the day.

CBB Parlay Bet: Santa Clara ML (+130)

Game: No. 10 Santa Clara vs. No. 7 Kentucky

Time: 12:15 PM ET

We start off in the first game of the day, when the Kentucky Wildcats face the Santa Clara Broncos, widely considered the most dangerous 10-seed in the tournament.

The Dimers model gives Santa Clara a 55.8% probability to cover the 3.5-point spread, the highest for any team on Friday, and they are just one of four underdog teams we give at least a 40% probability to win their game.

Santa Clara has a tenacious defense that ranked Top 15 in steals per game, averaging almost double digits, and can sink a team when they dial in from the three-point line.

With our projected final score an 81-79 victory and best bet on them to cover +3.5, we put Santa Clara in live upset territory, with their base +130 odds benefiting from the boost at bet365.

CBB Parlay Bet: Clemson ML (+112)

Game: No. 8 Clemson vs. No. 9 Iowa

Time: 6:50 PM ET

Our second upset is in the Clemson-Iowa game, where the Dimers model projects just a 1-point victory for Iowa and a significant 47% upset probability, the highest for an underdog today.

Another team with great value to cover, Clemson gets a 55.6% probability at the 2-point spread, signaling another Dimers model best bet.

Though Clemson is now without star Carter Welling due to a torn ACL, the Tigers bring a top defense into a game that projects with a razor-thin margin of victory where a lone possession could be the difference between the upset or not, with the Tigers covering in both scenarios.

The value is on the spread but the boost from bet365 brings the Clemson ML into fair odds territory in one of the day's tightest games.
