How the Boom Fantasy Promo Code Works

To take advantage of this welcome offer, new Boom customers simply need to create an account and make a minimum deposit of $10. Once your account is funded, play 5 lineups to automatically secure your bonus. This extra boost provides plenty of firepower to tackle the upcoming MLB slate. You can use your $55 in free lineups to build entries around J.T. Ginn and the Athletics taking on Shota Imanaga and the Chicago Cubs, or deploy them on any other baseball matchups on the board.

Please note that this offer is strictly reserved for first-time players. To successfully claim the bonus, you must be 18+ and physically located in one of the eligible participating states listed above.

How to Use Your Boom Fantasy MLB Bonus Tonight

Once you have secured your welcome bonus, you can begin constructing your free lineups using some of the most popular player props on the board. Below is a look at the current hits and strikeouts lines for some of tonight’s biggest stars, including the starting pitchers taking the mound for Los Angeles and Arizona:

PlayerHitsStrikeouts
Shohei OhtaniO/U 1.5N/A
Mookie BettsO/U 0.5N/A
Freddie FreemanO/U 1.5N/A
Ketel MarteO/U 1.5N/A
Corbin CarrollO/U 0.5N/A
Ian HappO/U 0.5N/A
Brent RookerO/U 0.5N/A
Ryne NelsonN/AO/U 4.5
Justin WrobleskiN/AO/U 3.5
Shota ImanagaN/AO/U 6.5

When making your lineup decisions, it pays to see where the underlying data leans to uncover market inefficiencies. For instance, Shohei Ohtani sits at a 1.5 hits prop. It does stand to reason that a multi-hit performance is a tall order against Arizona’s pitching staff, and the sharp play might be the under. Meanwhile, we put a lot of stock in teammates Mookie Betts and Corbin Carroll. Both players are strongly backed by the projections to clear their 0.5 hits lines, representing solid foundational value for your entries to get at least one base knock.

On the pitching side, the starting duel between the Dodgers and Diamondbacks presents contrasting outlooks. Justin Wrobleski projects well to surpass his 3.5 strikeouts mark, while the data indicates Ryne Nelson might struggle to clear his 4.5 strikeout line against a disciplined Los Angeles lineup.

Looking beyond the prime matchup to the rest of the evening slate (keep in mind all first pitches are based on standard Eastern Time scheduling), Cubs starter Shota Imanaga leans toward the under on his 6.5 strikeouts prop. If you are hunting for reliable hitters in that game, both Ian Happ and Brent Rooker are heavily supported by the models to successfully go over their 0.5 hits projections.
