If you are in MI, NJ, PA or WV, you can sign up to get the $150 bonus offer. The important part to take note of is that you have to win your initial $10 bet to get the bonuses. If you are in another eligible state, you can get the $1,500 first bet safety net. Wager any amount up to $1,500 knowing that you will get a bonus refund if your bet settles as a loss.

The first game today is Mariners-Tigers with Logan Gilbert and Jack Flaherty starting for their respective teams. The first two games were decided by one run, so it will be intriguing to see how the series plays out as it shifts to Detroit.

The Yankees’ season is on the line against the Blue Jays in Game 3. They turn to Carlos Rodon as the series shifts to the Bronx, while the Blue Jays hope Shane Bieber can help them clinch a spot in the ALCS.

A bet on either of these games, or even one on an NHL opening night game will qualify for your welcome offer.
