All but two MLB teams are in action on Tuesday, with 14 games providing ample opportunities to form an MLB parlay. But why stop there, as one could form an MLB longshot parlay with the hopes of a huge return. From money line picks to home run props to alternate lines, there are several plus-money MLB picks one could seek out. Some of the top games today include Angels vs. Cubs (-146), Red Sox vs. Astros (-149) and Mariners vs. Yankees (-112).
Max Fried will take the mound for New York after going 6.1 scoreless innings on Opening Day. If you think another shutout performance is in order for Fried, then backing 0 ER allowed would result in a +290 payout. That could be a standalone MLB bet, or it could be one leg of a lucrative baseball longshot parlay.
