I’ve bet on MLB for a long time and tried 15+ different sportsbooks, compared the odds, done my research. I’d say the best is Mybookie sportsbook.
First off, they have better odds for MLB than others, you can compare their betting lines to others, you will see a difference.
Fees are low, so you keep more.
They have free live streaming for all MLB games along with live bets, which other bookmakers don’t have. A huge plus.
And a welcome bonus of $1000, which tops most sportsbooks.
