College basketball conference tournaments are in full swing, and Monday night’s schedule features several important matchups that could impact teams’ chances of reaching the NCAA Tournament. Fans will be watching closely as Oregon State faces Gonzaga, Detroit Mercy meets Robert Morris, and Santa Clara takes on Saint Mary’s in key semifinal games.   For new bettors looking to get involved in the action, BetMGM Sportsbook is offering a welcome promotion with up to $1,500 in bonus bets, including up to $150 in bonus bets if your first bet doesn’t win.     BetMGM Sportsbook Welcome Offer   The BetMGM bonus code welcome offer gives new players the chance to place their first wager with added protection.

Make your first deposit. Place your first bet on any eligible sporting event. If your first bet loses, receive up to $150 back in bonus bets.   With multiple conference tournament games taking place this week, bettors will have plenty of opportunities to use their bonus bets.     Oregon State vs Gonzaga - WCC Tournament Semifinal   The West Coast Conference semifinal begins at 6:00 PM ET, with Gonzaga entering as one of the tournament favorites.   The Bulldogs have been a dominant force in the WCC for years and once again bring a strong offense and experienced lineup into the postseason. Oregon State, however, has already shown resilience during the tournament and will be hoping to slow Gonzaga’s tempo while creating scoring opportunities of their own.   With a place in the conference championship on the line, both teams will be highly motivated to deliver their best performance.     Detroit Mercy vs Robert Morris - Horizon League Semifinal   Another important semifinal takes place at 6:30 PM ET, when Detroit Mercy faces Robert Morris in the Horizon League Tournament.   Robert Morris has been one of the most balanced teams in the conference this season, relying on strong defense and efficient scoring to reach the semifinal stage. Detroit Mercy, meanwhile, will look to create offensive momentum early and pressure Robert Morris throughout the game.   Because a championship game berth is at stake, expect a competitive matchup that could come down to the final minutes.     Santa Clara vs Saint Mary’s - WCC Tournament Semifinal   The second WCC semifinal tips off later tonight at 8:30 PM ET, featuring Santa Clara vs Saint Mary’s.   Saint Mary’s is known for its disciplined style of play and strong defensive approach, often controlling the pace of games and forcing opponents into difficult shots. Santa Clara will need an aggressive offensive strategy to keep the Gaels from dictating the tempo.   With Gonzaga potentially waiting in the championship game, both teams will be aiming to secure their spot in the WCC final.     Conference Tournament Week Brings Plenty of Action   Conference tournament week is one of the most exciting periods of the college basketball season. Teams are competing not only for conference titles but also for automatic bids to the NCAA Tournament.   Promotions like the BetMGM Sportsbook welcome offer with up to $1,500 in bonus bets give new bettors a chance to get involved while reducing the risk of their first wager.   Whether you’re backing Gonzaga in the WCC semifinal, picking an upset in the Horizon League, or betting on Santa Clara vs Saint Mary’s, tonight’s games offer plenty of opportunities to enjoy the excitement of college basketball postseason action.
