Best BetMGM Sportsbook Round of 64 Prediction

In the Michigan vs. St. Louis matchup at 12:10 p.m. ET on CBS, the Wolverines are 12.5-point favorites. The massive spread surprises me, considering the Billikens were 28-5 going into the NCAA Tournament, plus Thursday's 25-point rout over an SEC opponent to boot.

Early on, we saw a lot of Billiken backing moving the spread slightly down from the opening -13. Nevertheless, I believe St. Louis keeps it under double digits, and covers the 12.5-point spread.

  • Michigan vs. St. Louis prediction: St. Louis +12.5 (-110)

A Billikens' spread would make you a slight $9.09 profit, but the $150 in bonus bets from the BetMGM bonus code ACTIONGET is the real prize we're looking for.

In addition to Michigan vs. St. Louis, you can pick which twin will win in the Haley vs. Hannah Cavinder matchup on BetMGM Sportsbook. Make the right pick to win your share of $2 million in bonus bets from BetMGM.
