March Madness Betting Odds For 3/14

There are two college basketball betting games taking place on Tuesday, March 14. The two games, including their betting odds, are the following:

• 16 Southeast Missouri State Redhawks vs. 16 Texas A&M Corpus-Christi Islanders (-4, 155), 6:40 p.m. EST

The Redhawks and Islanders meet in this First Four matchup to determine who moves ahead in the South Region. The Redhawks have gone 19-16 so far this season, while the Islanders have a slightly better record at 23-10. 

It should be a competitive game, as indicated by the close betting line, but with the Islanders having the better record, they are favored to win the game.
