Expert Picks and Chances to use BetMGM Bonus Code WSNSPORTS for Nationals vs. Marlins

When using a sportsbook promotion, it is smart to understand how the specific bonus works to help you make your choices. Whether you are using the BetMGM Bonus Code WSNSPORTS for a safety net on a larger bet or trying to win a "Bet and Get" offer, here are a few ways to look at the game.

• For the First Bet Offer ($1,500): Since this offer gives you bonus bets back only if you lose, some people prefer taking a shot at an underdog or a plus-money play like the Nationals Moneyline (+105). If the Nats win, you keep the cash. If they lose, you get another chance with the bonus bets.

• For the Bet and Get Offer ($150): This offer requires your team to actually win the game to trigger the bonus. In this case, choosing a team with better odds to win outright, like the Marlins Moneyline (-125), might be a more direct path to seeing that bonus in your account.

• Considering the Pitching: With Foster Griffin pitching well for Washington, the Under 8.5 runs could be a focal point if you expect a low-scoring duel, though early season games in Miami can sometimes be unpredictable.
